As obvious as it seems, customer value is defined by no one but the customer.
— Mark Rosenthal (2009)
After reading this chapter, you will be able to
- Define basic terms such as budget, estimate, price, cost, and value
- Discuss the relationship between scope changes and cost and budget overruns
- Explain basic concepts related to budgeting
- Identify different types of costs, and discuss issues related to contingency funds, profit, and cost estimating
- Explain the benefits of target-value design
- The project manager’s biggest job is delivering value as defined by the customer. A more geometric order focus on the project’s budget is also important, but never as important as delivering value as defined by the customer.
- Managing value and cost requires constant engagement with the customer, and a mutual understanding of basic terminology like budget and estimate.
- When creating an estimate, don’t confuse precision with accuracy.
9.1 Talking the Talk
Nearly all projects require money to pay for the required resources—labor, services, and supplies. Project success requires that project managers accurately identify the money needed for a project, acquire the commitment of those funds through a budgeting process, and then successfully manage the expenditure of those funds to achieve the desired outcomes. Your ability to manage stakeholder expectations and commitment related to project funds, combined with your ability to effectively manage the use of those funds to deliver results, will form the basis of your reputation as a reliable project manager.
An important step in ensuring that a project unfolds smoothly is to make sure everyone is using similar terminology. Terminology is important in any technical endeavor, but when it comes to a project’s overall value, miscommunications resulting from incorrectly used terms can result in misaligned expectations and erode trust among project participants. Unfortunately, this type of miscommunication is extremely common. So, let’s start with some basic terms:
- budget: The funds that have been allocated for a project.
- estimate: An assessment of the likely budget for a project. An estimate involves counting and costing and is based on ranges and probabilities. Throughout a project, managers and team members are asked to estimate remaining work, cost at completion, and required remaining time. An estimate is a forward projection, using what is known, to identify, as best as possible, the required effort, time, and/or cost for part or all of a project.
- price: “A value that will purchase a finite quantity, weight, or other measure of a good or service” (Business Dictionary). The price of a purchased unit is determined by the market.
- cost: “An expenditure, usually of money, for the purchase of goods or services” (Law 2016). Practically speaking, project cost (and its relationship to revenue or approved expenditures) is the thing management cares about most. Note that, like all terms, the meaning of “cost” varies somewhat from industry to industry. For example, in product development, the term has three specific meanings: 1) cost to create the product or project; 2) cost to establish a manufacturing cell capable of producing the product; and 3) cost of the final good or service to the market.
- value: “The inherent worth of a product as judged by the customer and reflected in its selling price and market demand” (Lean Enterprise Institute 2014). Project managers have to think about two kinds of value—target value, or the value the stakeholders hope to achieve, and delivered value, the value actually generated by the project. You’ll learn more about target value later in this lesson.
The following scenario illustrates use of these related concepts. Suppose you set $100 as your monthly gas budget at the beginning of the year. However, because the current price of gas is $5.50 a gallon, which is higher than normal, you estimate that you will actually spend $130 on gas this month. You won’t know your cost for gas until you make your final purchase of the month and add up all the money you spent on fuel. If you wind up having to take an unexpected out-of-town trip, then your cost could be quite a bit higher than your estimate. Or, if the price of gas drops suddenly, say to $1.60 per gallon, your cost will turn out to be lower. In any case, the cost is a simple summation you can do looking backwards. But the value of your month of travel is something only you can define. If your unexpected out-of-town trip results in some compelling new business opportunities, then you would likely value the trip very highly. But if the weather prevents you from reaching your destination, and then you get lost on the way home, you would probably assign a low value, as experienced, to your misbegotten adventure. Much like in a project, the delivered value may fall short of the target value.
In the real world, these terms do not always mean the same thing to everyone. Worse, people sometimes use them interchangeably or use them to mean different things in different situations. In particular, the terms budget and estimate are often incorrectly used as synonyms, as are the terms cost and price. The end result of this confusion can be a lack of clarity among project partners regarding project goals and constraints. It helps to keep in mind that a budget, an estimate, a target value, and a price are tools to help guide the project team, whereas cost and delivered value are project outcomes that help determine project success. Budgeting and estimating are tools we use to try gauge cost and create value. But they don’t cause cost. Project cost is driven by scope, required resources to accomplish the scope, and related prices.
Delivering value is your primary job as a project manager. But of all the terms related to budgeting a project, the meaning of “value” can be most difficult to grasp. The important thing to remember is that value is determined by the customer, and then flows back to all participants, shaping all project activities. As a project manager, you need to engage with the customer to identify the project’s real value. At the same time, you might also need to take a longer view of value. For example, your organization might be better able to offer value to future customers by carefully studying all projects at completion to capture lessons learned—information that can then be used to improve future projects. The value of this investment of resources may not be apparent to customers, who are only focused on their particular projects, as it mainly benefits future projects. But the overall process benefits all customers in the long run.
As you work on the project’s budget, and perhaps face difficult decisions, you need to focus on tasks that create value. According to the Lean Lexicon, a good test for identifying a value-creating task “is to ask if this task could be left out without affecting the product. For example, rework and queue time are unlikely to be judged of any value by customers, while actual design and fabrication steps are” (Lean Enterprise Institute 2014). This article walks through an example of a home construction project that could have turned out much better for the home owners—who were forced to live in a trailer with no running water during the project—if the builder had focused on providing “chunks” of immediately usable value, such as a working bathroom (Lloyd 2015): http://project-management.com/understanding-lean-project-management/. As you’ve learned in earlier lessons, that’s exactly what Agile project management does in the world of IT. At the end of each sprint, the customer is in possession of a piece of working software.
Throughout any project, you need to do all you can to get stakeholders to focus on the success of the whole project, and not just their individual parts. One way to do this is to make sure everyone understands what the project value is, and then encourage them to optimize the flow of the project. As the project evolves, the project team should continue to refine its understanding of project value; refine its estimate of required resources; and, if necessary, modify the approved budget or adjust scope so that costs do not exceed the budget.
In product development, it is helpful to think of value as an attribute or feature for which customers will pay a premium. Customers may pay more for smaller size, longer life, better aesthetics, or more durable products. Depending on the use of the product being created, these may be more or less important. Susan Ottmann, program director for Engineering Professional Development at the University of Wisconsin-Madison, points out that “Schneider Electric produces two types of load centers for the U.S. market. (A load center is the box in your home that houses circuit breakers.) The QO brand is differentiated from the Homeline brand by a higher level of durability and quality. Although both perform the same function, the technology inside the breakers is slightly different. Presumably, QO has made the calculation that some customers will be willing to pay more for a higher quality product” (pers. comm., June 6, 2018).
9.2 Keeping an Eye on Scope
A project’s budget, estimate, and cost are all affected by the project’s scope. Anyone who has ever remodeled a bathroom in an old house is familiar with the way scope can change throughout the course of a project. The fact is, you can’t really know how much the project is going to cost until you tear up the floor and get a look at the state of the old plumbing. Boston’s Big Dig—which was estimated to cost $2.8 billion, but ultimately cost $14.6 billion—is a more extreme example of the same principle at work: It is difficult to precisely predict the cost of any endeavor at its outset.
A good rule of thumb is to assume that whatever can go wrong probably will go wrong. For example, to return to the remodeling example—rather than naively hoping for the best, you’d be wise to assume that everything old will have to be replaced when you begin pulling up the floor in a fifty-year-old bathroom. Overly optimistic assumptions about risk and scope are a leading cause of unrealistic estimates. Assuming everything will have to be replaced would help set an estimate for the upper bound of a likely range of costs for the project. Estimates should include a range, which can be narrowed as more is learned about actual project conditions.
Examples of cost and time overruns are easy to find. Here are just a few sources to give you a sense of the magnitude of the problem, which is especially acute in massive megaprojects:
- A report on overruns in the energy industry: http://www.ey.com/Publication/vwLUAssets/EY-spotlight-on-oil-and-gas-megaprojects/$FILE/EY-spotlight-on-oil-and-gas-megaprojects.pdf
- A Forbes article describing the vast costs of hosting the Olympic games: http://www.forbes.com/sites/niallmccarthy/2016/08/04/the-massive-cost-of-hosting-the-olympic-games-infographic/#66c9ad79ddf7
- A slide collection from MSN.com documenting budget-busting megaprojects in a variety of industries: https://www.msn.com/en-us/money/markets/budget-busting-megaprojects-coming-soon-%E2%80%93-or-are-they/ss-BBQ7nf5?li=BBnb7Kz&ocid=UP97DHP
When asked to defend mounting costs, project managers will sometimes argue that the cost increased because the scope evolved, when in fact the real culprit is scope creep. As discussed in Lesson 4, scope evolution, or managed change, is a natural and rational result of the kind of learning that goes on throughout the course of a project. It is a conscious, managed choice caused by externalities that forces you to reconsider project essentials in order to achieve the intended project value.
Scope creep, by contrast, is caused by unmanaged changes to the project scope. It might add value from the customer’s perspective, but the time, money, and resources consumed by the change of scope lead to additional overruns. Scope creep tends to happen when no one is paying attention to the project’s scope.
The key to managing scope changes is a process for early identification, review, and approval of requested changes to project scope. A Scope Change Request—or a Project Variation Request (PVR) as it is sometimes called— is a form that must be signed by all affected stakeholders prior to implementation. This article by Tom Mochal provides some helpful guidelines for managing scope changes: http://www.techrepublic.com/article/follow-this-simple-scope-change-management-process/. You can download a sample Scope Change Request form here: http://www.demo.projectize.com/pmf/templates/63.doc
9.3 Understanding Budgets
Budgeting is an exercise in refining your focus. You start with a wide-angle estimate, in which the details are necessarily fuzzy, and bit by bit zero in on a sharper picture of project costs. You might be temperamentally inclined to try to nail down every figure in an early draft of a budget, but in fact you should only develop a budget at the precision needed for current decisions. Your overall precision can and should advance as the project advances.
This is especially important in the earliest stages of the budgeting process, when you are working out rough estimates. Take care to estimate at the appropriate level of precision: Don’t make the mistake of thinking you can estimate costs to the exact penny or dollar. $378,333.27 is not a realistic or intelligent estimate. Ultimately, overly precise budgets represent a communication failure. By proposing a budget to the customer that contains overly precise figures, you risk giving a false sense of accuracy regarding your understanding of and knowledge about the project.
In the early stages of the budgeting process, when you are still working out estimates, it’s helpful to include an uncertainty percentage. A typical approach is to include a +/- percentage, such as $400,000 +/- 10%. The percentage may initially be large but should gradually decrease as the project progresses and the level of uncertainty declines. For IT projects, which are notoriously difficult to estimate, consider going a step further and adding an uncertainty percentage to every line item. Some items, such as hardware, might be easy to estimate. But other items, such as labor to create new technology, can be extremely difficult to estimate. These line item variances can influence the total estimate variance by a significant amount in many projects.
But even when you have a final budget in hand, you need to prepare for uncertainty by including an official contingency fund, which is a percentage of the budget set aside for unforeseen costs. Contingency funds are described in more detail later in this lesson.
Successful project managers use the budgeting process as a way to create stakeholder buy-in regarding the use of available resources to achieve the intended outcome. By being as transparent as possible about costs and resource availability, you’ll help build trust among stakeholders. By taking care to use the right kinds of contracts—for example, contracts that don’t penalize stakeholders for escalating prices caused by a changing economy—you can create incentives that keep all stakeholders focused on delivering the project value, rather than merely trying to protect their own interests. The relationship between costs and contracts is discussed in more detail later in this lesson.

9.4 Understanding Cost
Ultimately cost, the number management typically cares about most in a for-profit organization, is determined by price. For many projects, it’s impossible to know the exact cost of an endeavor until it is completed. Stakeholders can agree on an intended value of a project at the beginning, and that value has an expected cost associated with it. But you may not be able to pin down the cost more precisely until you’ve done some work on the project and learned more about it.
To estimate and manage costs effectively, you need to understand the different types of costs:
- direct costs: “An expense that can be traced directly to (or identified with) a specific cost center or cost object such as a department, process, or product” (Business Dictionary n.d.). Examples of direct costs include labor, materials, and equipment. A direct cost changes proportionately as more work is accomplished.
- direct project overhead costs: Costs that are directly tied to specific resources in the organization that are being used in the project. Examples include the cost of lighting, heating, and cleaning the space where the project team works. Overhead does not vary with project work, so it is often considered a fixed cost.
- general and administrative (G&A) overhead costs: The “indirect costs of running a business,” such as IT support, accounting, and marketing” (Investing Answers n.d.).
The type of contract governing your project can affect your consideration of costs. As explained in Lesson 4, the two main types of contracts are fixed-price and cost-plus. Fixed price is the more predictable of the two with respect to final cost, which can make such contracts appealing to the issuing party. But “this predictability may come with a price. The seller may realize the risk that he is taking by fixing a price and so will charge more than he would for a fluid price, or a price that he could negotiate with the seller on a regular basis to account for the greater risk the seller is taking” (Symes 2018).
Many contracts include both fixed-price and cost-plus features. For example, they might have a fixed price element for those parts of the contract that have low variability and are under the direct control of the project team (e.g., direct labor) but have variable cost elements for those aspects that have a high degree of uncertainty or are outside the direct control of the project team (e.g., fuel costs or market driven consumables).
If money is not available from other sources, then cost overruns typically result in a change in the project’s scope or a reduction in overall quality. To prevent this, organizations build contingency funds into their budgets. Technically, a contingency fund is a financial reserve that is allocated for identified risks that are accepted and for which contingent or mitigating responses are developed. The exact amount of a contingency fund will vary, depending on project risks; a typical contingency fund is 10% to 15% of the total budget but depends on the risks associated with the project.
From the Trenches: John Nelson on Cost Planning and Living Order
John Nelson summarizes his thoughts on cost planning, based on his decades of work on capital projects, as follows:
Conceptual planning takes place in living order. Cost management, when done right, starts out in living order, but moves into a very strict geometric order. Unfortunately, it is rarely done right. Between 2/3 and 3/4 of all projects worldwide end up costing more than originally planned. Getting the costs wrong during the planning stage can result in huge consequences for a project, and possibly for your career. Major cost busts can follow you around for the rest of your working life. If you cost something incorrectly, you’ll have to make corresponding downgrades in scope and quality. For example, many college campuses have new buildings with two or three empty floors because the money ran out before they could be finished. You really don’t want to be the project manager responsible for a costing error of that magnitude, which is sometimes referred to as a CLM, or career limiting move.
Even worse, companies that get costs wrong and underbid a project sometimes try to salvage a profit by illegal means—perhaps by using cheap materials or cutting corners on safety. On public projects, such as highways or schools, huge costing errors can result in loss of public trust, making it more difficult for the public agency to do more work in the future. In that case, a cost bust can be an OLM—an organizational limiting move.
Accurately and precisely predicting the cost of a project is very difficult. You need to start with humility and curiosity, expending a great deal of effort to get the numbers right, especially when it comes to parts of the project you don’t understand. This is true for small projects, like a bathroom renovation in an old house, where you simply don’t know what you’re going to find until you start opening up the walls. It’s also proven true for huge undertakings like the Big Dig, Boston’s tunnel megaproject, which ended up with a cost overrun of 190%. (2017)
Contingency funds are often available to pay for an agreed-upon scope change. However, some project managers make a practice of treating a contingency fund as a “Get Out of Jail Free” card that they can use to escape any cost limitations. Some, as a practical matter, will artificially inflate a contingency fund to ensure that they have plenty of resources to draw to manage any unforeseen future risks. But that is never a good idea because if you wind up with a large contingency fund that you ultimately don’t spend, you have essentially held that money hostage (i.e., lost opportunity costs) from the rest of the enterprise. That can be as damaging to your organization’s mission as a cost overrun that prevents you from finishing a project.
As explained in Lesson 8, contingency funds are a form of risk management. They are a necessary tool for dealing with uncertainty. Unfortunately, as necessary as they are, it’s not always possible to build them into your approved budget. For example, if you are competitively bidding on a contract that will be awarded on the lowest cost, then including a contingency fund in your estimate will almost certainly guarantee that your company won’t win the contract. It is simply not practical to include a contingency fund in a lump sum contract.
In the living order approach to this problem, the owner maintains a shared contingency fund instead and makes it available, upon justification, for all project stakeholders. This approach helps ensure that project participants will work collaboratively with the project sponsor to solve any problems they might notice, confident that there is money available to address problems that threaten project value or to leverage opportunities that will provide greater project value. For example, in a lecture on Lean and integrated project delivery, David Thomack, a long-time veteran of the construction industry, explained how the Boldt Company and other stakeholders involved in a $2 billion healthcare project protected millions of dollars in contingency funding, which was then ultimately shared among all stakeholders (Thomack 2018). Such shared contingency funds are typically spelled out in the project contract and are an effective tool to manage risk and uncertainty. Although some organizations only manage out-of-pocket project costs, best practice is to manage total cost, including costs associated with staff (engineering, purchasing, testing, etc.) working on the project.
In private enterprise, cost management is directed toward maximizing profit. A private or publicly-traded organization cannot stay in business unless they are profitable. But that doesn’t mean that every project is primarily a profit-maximizing undertaking. Certainly, individual projects (such as developing a new product or completing a design for a client) may have a goal of generating profit. However, some projects (such as deploying an enterprise software system or meeting a regulatory compliance requirement) may not in themselves generate profit, but rather support the broader organization in generating profits. Within governmental and non-profit organizations, projects are not designed to generate profits but might be launched to reduce costs or generate net revenues that can be used to cover other costs within the organization.
As a project manager, you need to understand the financial expectations for your projects. Make sure you know how the financial performance of your project affects the financial performance of the associated project portfolio and the overall organization. This understanding will help you advocate for your proposed project. It will also enable you to better justify changes to the project’s scope and budget, based on the project’s proposed value.
As a general rule, chasing profits at the expense of both your organization’s larger mission and the value your organization wants to offer to customers is not sustainable. A relentless focus on profit alone can wreak havoc on a project as project managers are forced to reduce quality or slow the schedule to meet a carved-in-stone budget that will supposedly ensure profitability. In such situations, however, profitability is nearly always defined in the short-term. A fixation on short-term profits can, paradoxically, lead to spiraling losses in the long term—perhaps because unsatisfied customers take their business elsewhere. Likewise, chasing excessive quality or accelerated schedules can be equally elusive.
Ideally, some kind of financial metric is associated with the success of any project and is spelled out in the contract. A collaborative approach to contracts and procurement helps keep all stakeholders focused on the project’s intended value rather than simply on short-term profits.
Estimating costs accurately is essential to any organization’s success. In fact, in many industries, the knowledge involved in cost estimating is actually a valuable form of intellectual property. The ability to estimate costs is part of a company’s overall competitive advantage and a skill required in most industries. There are two basic types of estimating:
top-down estimates: Estimates that “usually are derived from someone who uses experience and or information to determine the project duration and total cost. However, these estimates are sometimes made by top managers who have very little knowledge of the component activities used to complete the project” (Larson and Gray 2011, 134). A top-down estimator generates an expected total for the entire project and then divides up that total among the various project tasks.
- bottom-up estimate: “A detailed cost estimate for a project, computed by estimating the cost of every activity in a work breakdown structure, summing these estimates, and adding appropriate overheads” (Business Dictionary n.d.). A bottom-up estimator divides the project into elements and tasks, estimates a cost for each, and then sums all estimated costs to create a total for the project. A common problem with simple bottom-up estimates is that they often overestimate costs that cannot be justified by market conditions. Total projected costs need to be compared with market realities, and task estimates of planned work and associated costs may have to be adjusted to reach a feasible budget for the overall project. Note that pressure to make such adjustment can encourage the sponsor to try to make the numbers work any way possible, perhaps by overstating the benefits of the project (e.g., higher sales volume than the market forecast predicts) or planning for the project team to do more work faster than is realistic. Ultimately, this is an ethical issue and could end up costing your reputation. It’s essential that you remain truthful about the realities of your projects as you estimate their costs.
A third type, iterative estimating, combines the best of top-down and bottom-up estimating. Iterative estimating is a process of refining an estimate by taking into account information typically used in a top-down estimate (such as past history of similar projects) and detailed information generated by bottom-up estimating. Iterative estimating takes place in living order and relies on negotiation and coordination among the project stakeholders. It only works if past work is representative of future work, which you can really only determine if you are producing small batches. One type of iterative estimating, phase estimating, is “used when the project is large or lengthy or is developing something new or untried for the organization. In phased estimates, the near-term work is estimated with a high level of accuracy, ±5 – 15%, whereas future work is estimated at a high level with ±35% accuracy” (Goodrich n.d.). As the project advances through major phases, the budget for subsequent phases is intentionally reviewed and refined in light of knowledge gained to date.
According to David Pagenkopf, IT project managers use yet another type of estimating called parametric estimating, which is a way to “use experience from parts of other projects to come up with estimates for work packages that are similar to past work, but not the same.” For example, he explains that “if a ½ ton Ford pick-up gets 20 mpg on the highway then I can estimate that a ½ ton GMC pick-up may get 20 mpg on the highway. That information may be helpful in determining the entire cost of a trip that involves the use of multiple rented trucks. Actual mileage will vary, but without testing the GMC truck and collecting data, I can reasonably estimate mpg for it” (pers. comm. June 1, 2018).
9.5 Target-Value Design
Despite all the effort organizations put into cost management, cost overruns remain a fact of life. For example, in a study of 1,471 IT projects, Flyvbjerg and Budzier found
The average overrun was 27%—but that figure masks a far more alarming one. Graphing the projects’ budget overruns reveals a “fat tail”—a large number of gigantic overages. Fully one in six of the projects we studied…[had] a cost overrun of 200%, on average, and a schedule overrun of almost 70%. This highlights the true pitfall of IT change initiatives: It’s not that they’re particularly prone to high cost overruns on average, as management consultants and academic studies have previously suggested. It’s that an unusually large proportion of them incur massive overages. (2011)
Cost overruns occur for many reasons, including lack of sufficient knowledge about the project, inability to obtain funding for the full scope of the desired work, uncertainty about the feasibility of the project, and conflicting priorities. Using only the traditional, geometric approach to cost management fails to encourage broad on-going stakeholder engagement and collaboration that can prevent these problems. You will get far better results by incorporating the living order principle of target-value design, a cornerstone of Lean project delivery in the construction field which has applications in nearly all areas of project management. A target value is the output stakeholders want the project to generate. Target-value design focuses on creating the best possible target value for the customer without exceeding the project’s target costs. It requires a fundamental shift in thinking from “expected costs” to “target cost.” The target-value design process is collaborative and iterative, typically requiring frequent refinement and conversation among project stakeholders.
For a quick, thirty-second introduction to target-value design, see this video:
In the traditional budget process, the estimate is based on a detailed design and project plan. In target-value design, you start with the intended value of the project, and then design and plan a project that will deliver the intended value for the targeted cost. In other words, the project’s value and associated budget determines the project’s design, and not the other way around. This is nothing new for product development teams, who nearly always have to design their products for particular price points. But the degree of engagement with the customers required in target value design to find out what customers really want is not something most product development teams are used to. In any industry, the goal of target-value design is hitting the sweet spot of what you can get for the right price, schedule, and quality. For example, the whole point of Agile software development is continually refocusing the project in an attempt to achieve the desired target-value.
Thinking About Value
According to John Nelson, you can’t get the costs right on a project until you understand what the customer values. To do that, you need to understand what value really means:
We make value-based decisions all the time. But different people value different things. For instance, in Wisconsin, you might choose to drive an inexpensive car, so you don’t have to worry about it getting damaged on icy winter roads. A realtor, who has to drive clients around in her car, might choose a more comfortable, expensive vehicle. There’s no right or wrong in these decisions. You’re both right.
Keep in mind that a moral value is different from a project value. Moral values are about right and wrong. Project value is concerned with the worth of something—and the only person who can determine that is the customer. The only time an engineer can object to the customer’s definition of project value is when the customer asks for something that is a threat to human safety or is illegal.
When costing a project, you need to figure out what your customer’s value threshold is. You don’t want to build the best thing ever built if that’s not what they want. So, the first step in the target value process is to get the customer to explain her definition of value. To do that, you need to have open conversations in which you keep asking questions, all the while making it clear you are eager to learn what the customer wants. At this stage, it’s essential to resist the temptation to over-promise what you can deliver. One way to avoid this is to continually engage with the customer about value, budget, and schedule. (2017)
According to John Nelson, in capital projects, a target value cost model is “a framework of estimates and budgets that changes over time” (2017). The process entails “many conversations about price, cost, budget, and estimate, and at the same time discussions with the customer about what they really value.” When done right, it transforms “cost management from a calculation performed in isolation by professional estimators, to a process of ongoing, collaborative learning about the project in which team members and the customers all have a role. It avoids the pitfall of having one person responsible for calculating a total cost, and another person responsible for delivering the project at that number” (2017).
The ultimate goal of target-value design is to reduce the waste and rework that normally arises in the design/estimate/redesign cycle. It necessarily involves cross-functional teams because no one party in isolation has the necessary knowledge to define project value and develop a project plan that most efficiently delivers that value. Target-value design integrates the definition of the project’s product/deliverables with the process used to deliver the project and with the associated project costs.
To help you implement target-value design in your organization, the Lean Construction Institute recommends nine “foundational practices.” These principles apply to all types of projects:
- Engage deeply with the client to establish the target-value. Both designers and clients share the responsibility for revealing and refining concerns, for making new assessments of what is value, and for selecting how that value is produced. Continue engaging with the client throughout the design process to uncover client concerns.
- Lead the design effort for learning and innovation. Expect the team will learn and produce something surprising. Establish routines to reveal what is learned and innovated in real-time. Also expect surprise will upset the current plan and require more replanning.
- Design to a detailed estimate. Use a mechanism for evaluating design against the budget and the target values of the client. Review how well you are achieving the targets in the midst of design. When budget matters, stick to the budget.
- Collaboratively plan and re-plan the project. Use planning to refine practices of coordinating action. This will avoid delay, rework, and out-of-sequence design.
- Concurrently design the product and the process in design sets. Develop details in small batches (lot size of one) in tandem with the customers (engineer, builders, owner, users, architect) of the design detail. Adopt a practice of accepting (approving) completed work as you design.
- Design and detail in the sequence of the customer who will use it. This maintains attention to what is valued by the customer. Rather than doing what you can do at this time, do what others need you to do next. This leads to a reduction in negative iterations.
- Work in small and diverse groups. Learning and innovation arises socially. The group dynamics of small groups—8 people or less—is more conducive to learning and innovating: trust and care for one another establish faster; and communication and coordination are easier.
- Work in a big room. Co-locating design team members is usually the best option. Design is messy. Impromptu sessions among design team members are a necessary part of the process. So are regular short co-design sessions among various specialists working in pairs.
- Conduct retrospectives throughout the process. Make a habit of finishing each design cycle with a conversation for reflection and learning. Err on the side of having more retrospectives not fewer. Use plus|deltas at the end of meetings. Use more formal retrospectives that include the client at the end of integration events. Instruct all team members to ask for a retrospective at any time even if they just have a hunch that it might uncover an opportunity for improvement. (Macomber and Barberio 2007)
Costs in Practice
John Nelson’s work on the Discovery Building at the University of Wisconsin-Madison included an interesting example of the kind of value trade-off that occurs in target value design:
It turned out that the owner expected extremely high-quality lighting in the building, which put pressure on the target value for electrical. To that, we said, “Ok, we can increase the target value for electrical, but we can’t increase the project budget. So what system will we offset that with?” In the end, we used a flat slab concrete structure system that allowed us to take four feet out of the height of the building. We also used digital-integrated design, designing the entire building in AutoCAD, working out all the interferences before we went in the field. Taking four feet out of the height of the building allowed the skin price to come down, which offset the cost of the higher quality lighting. This is an example of the kind of give-and-take required to manage costs.
Value is at the heart of target-value design and is ultimately defined by the client. However, as a project manager, it’s sometimes your job to expand the client’s notion of what constitutes a project’s overall value, perhaps by encouraging the client to think about the project’s entire life cycle, from planning, to construction/manufacturing/implementation, to operation and support, and to product or facility retirement/ decommissioning.
So, what does target-value design look like in practice? Appendix A in The Design Manager’s Handbook (which is available online here: http://onlinelibrary.wiley.com/doi/10.1002/9781118486184.app1/pdf) includes some helpful examples (Mossman, Ballard and Pasquire 2013). Figure 9-1, created by The Boldt Company, provides a graphical representation of key milestones in a target-value design project.
This diagram shows that:
- The target cost was set at $13,100,000 by board approval.
- The initial estimated costs, exclusive of contingencies, were slightly above the target cost.
- The design was modified to enable estimated costs, including contingencies, to approach the target cost.
- The final design included owner-initiated changes that were covered by contingency allowances. As the project advanced, contingency funds were used as needed, although they were reduced as the team managed actual costs to align with estimates, with the goal of keeping total costs within the target budget.
- Unused contingency funds were available at the end to share among project partners.
- Throughout the project, participants took care to check in on the project’s scope, cost, and schedule. In any project, it’s essential to have some process for defining the project scope, identifying potential scope changes, and identifying the cost and schedule tradeoffs necessary to make those changes possible.
- When it comes to project costs, don’t try to be all things for all customers: Some organizations do better on low-cost projects, others on high-cost projects. Few can do both. If discussions about value during the planning stage tell you that the customer has a Mercedes appetite with a Chevrolet wallet, then you probably don’t want to work for that customer because you won’t be able to please them.
- Be prepared to learn: Throughout a project, you move along on a continuum of living order to geometric order, where things get more predictable as you proceed. But you never know the total cost of a project until it’s finished.
- Engage stakeholders throughout the budgeting process: It’s essential to keep the conversation going with stakeholders as you make trade-offs, so the stakeholders own all the value decisions
- Don’t shrug off a costing mistake by saying I could only estimate what I knew: To the customer, that means I didn’t know enough. Or worse, I didn’t take the time to learn enough. Be honest and humble about what you do and do not know about costs at any given point, avoid giving the impression that you know more than you do, and never be more precise than is justified.
- Avoid the jargon guaranteed maximum price with qualifications: This phrase, which is very common in the construction industry, is an oxymoron. Something can’t be both guaranteed and qualified.
- Cultivate informed intuition: Developed through experience, informed intuition can be a huge help in estimating. Your informed intuition will improve as you repeat similar projects. In the early stages of your career, seek out mentors who can help speed up your acquisition of informed intuition.
- Don’t make the mistake of waiting to look at costs, budgets, and estimates until you reach a milestone: At that point it’s usually too late. To avoid surprises, check in with the numbers throughout the project. Strive to get the big things right at the beginning, using informed intuition for unknowns. Throughout the project, be prepared to adjust, reset, or stop proactively if a budget bust or estimate overrun seems likely.
- Remember that production/construction costs are not the end of the story: You also need to be upfront about the difference between the production/construction costs, and the total cost of ownership. For example, the total cost of ownership for an engine would include maintenance and replacement parts. In capital projects, this includes fees, furniture, and contingency funds, which can add 30% to 40%. In IT, the life-cycle cost includes maintenance, which is typically 20% of the purchase price.
- Understand the difference between costs in public and private domains: Sometimes, in the public domain, in a very rigid design-bid-build situation, you are given a number for the amount of money you are able to spend. In that case, you simply have to design the project to meet that number. That’s not target valuing. That’s reverse engineering to meet a specific cost at a minimum level of quality.
- Be realistic about your level of uncertainty: At all times, avoid misleading stakeholders into thinking your current level of accuracy is higher than it actually is. Be honest about the fact that the project team’s ability to be accurate will improve over time, as the team gains more information about the project.
- Learn about the financial environment in which your project will unfold: Make sure you understand the financial planning methods of your business. In some companies, costs of test facilities are considered overhead and are part of general and administrative fixed costs. In other companies, the same internal costs are charged directly to each individual project on a “per use” basis. This can drastically affect final project cost viability. Understanding how your company allocates costs and what needs to be included in the project budget is essential for good planning. A best practice way to do this is to have your project plans and budgets audited by a project manager experienced in the company processes.
- Manage contingency funds at a project level: In the same way that a gas expands to fill the available space, spending expands to match the available budget. For this reason, contingency is best managed at a project level, not a task level.
- Create a shared contingency fund: Whenever possible, create a shared contingency fund for the project, so that all stakeholders benefit from staying on budget or are hurt by cost overruns.
- Remember that, in product development, a lower-than-expected volume can affect profitability: In product development, the cost of a product at launch is often higher than expected due to lower volumes. This may impact profitability. Make sure your team understands the path to reaching the target cost at the target volume with contingencies if anticipated volumes are not attained. This is especially true in industries with high fixed costs and low manufacturing costs, such as the pharmaceutical industry.
- Think about possible tradeoffs: Scope, costs, and schedule will typically change as a project advances. As project circumstances evolve, keep asking yourself, “What trade-offs can my team make that are in the project’s best interests?”
- Be prepared to work with a predefined budget: A budget negotiation process in which the team is free to discuss the project and make suggestions is ideal, but sometimes an organization’s leader creates a budget for a project, and the assigned team is charged with making it work one way or the other. In that case, you will need to assess the feasibility of achieving the project’s goals with the assigned budget and either: 1) lead the team in developing an appropriate project strategy and plan; or 2) negotiate with the project sponsor to modify the scope and/or budget to enable your team to confidently commit to delivering the project’s value.
- Terminology is important in any technical endeavor, but when it comes to a project’s overall value, miscommunications resulting from incorrectly used terms can result in misaligned expectations and erode trust among project participants. Make sure you understand the difference between budgets and estimates, and the difference between price and cost. Of all the terms related to budgeting a project, the meaning of “value” can be especially difficult to grasp. The most important thing to remember is that value is determined by the customer and then flows back to all participants, shaping all project activities. Delivering value is your primary job as a project manager.
- A project’s budget, estimate, and cost are all affected by the project’s scope. When asked to defend mounting costs, project managers will sometimes argue that the cost increased because the scope evolved, when in fact the real culprit is scope creep. The key to managing scope changes is a Scope Change Request—or a Project Variation Request (PVR) as it is sometimes called—which is a form that must be signed by all affected stakeholders prior to implementation.
- Budgeting is an exercise in refining your focus. You start with a wide-angle estimate, in which the details are necessarily fuzzy, and bit by bit zero in on a sharper picture of project costs. Take care to estimate at the appropriate level of precision: Don’t make the mistake of thinking you can estimate costs to the exact penny or dollar. Successful project managers use the budgeting process as a way to create stakeholder buy-in regarding the use of available resources to achieve the intended outcome. By being as transparent as possible about costs and resource availability, you’ll help build trust among stakeholders.
- To estimate and manage costs effectively, you need to understand the different types of costs, including direct costs, direct project overhead costs, and general and administrative (G&A) overhead costs. The type of contract (for example, fixed-price versus cost-plus) governing your project can affect your consideration of costs. If money is not available from other sources, then cost overruns typically result in a change in the project’s scope or a reduction in overall quality. To prevent this, organizations build contingency funds into their budgets. The exact amount of a contingency fund will vary, depending on project risks; a typical contingency fund is 10% to 15% of the total budget but depends on the risks associated with the project. Shared contingency funds can encourage stakeholders to focus on the well-being of the project as a whole rather than their individual stakes in the project.
- As a project manager, you need to understand the financial expectations for your projects. In private enterprise, cost management is directed toward maximizing profit. But that doesn’t mean that every project is primarily a profit-maximizing undertaking. Within governmental and non-profit organizations, projects are not designed to generate profits but might be launched to reduce costs or generate net revenues that can be used to cover other costs within the organization. A collaborative approach to contracts and procurement helps keep all stakeholders focused on the project’s intended value, rather than simply on short-term profits. Estimating costs accurately is also essential to any organization’s success, and you should be familiar with the two basic types of estimates—top-down estimates and bottom-up estimates—as well as iterative estimates, which combine the best features of top-down and bottom-up estimates.
- Target-value design, a cornerstone of Lean project delivery in the construction field, has applications in nearly all areas of project management. Target-value design focuses on creating the best possible value for the customer without exceeding the project’s target costs. It requires a fundamental shift in thinking from “expected costs” to “target cost.” The target-value design process is collaborative and iterative, typically requiring frequent refinement and conversation among project stakeholders. The ultimate goal of target-value design is to reduce the waste and rework that normally arises in the design/estimate/redesign cycle.
- bottom-up estimate—“Detailed cost estimate for a project, computed by estimating the cost of every activity in a work breakdown structure, summing these estimates, and adding appropriate overheads” (Business Dictionary n.d.). A bottom-up estimator starts by dividing the project up into tasks, then estimates a cost for each task, and sums the total costs for all the project tasks.
- budget—The funds that have been allocated for a project.
- contingency fund—A financial reserve that is allocated for identified risks that are accepted and for which contingent or mitigating responses are developed. Contingency funds are also often available to pay for an agreed-upon scope change.
- cost—“An expenditure, usually of money, for the purchase of goods or services” (Law 2016). Note that, like all terms, the meaning of “cost” varies somewhat from industry to industry. For example, in product development, the term has three specific meanings: 1) cost to create the product or project; 2) cost to establish a manufacturing cell capable of producing the product; and 3) cost of the final good or service to the market.
- direct costs—“An expense that can be traced directly to (or identified with) a specific cost center or cost object such as a department, process, or product” (Business Dictionary n.d.). Examples of direct costs include labor, materials, and equipment. A direct cost changes proportionately as more work is accomplished.
- direct project overhead costs— Costs that are directly tied to specific resources in the organization that are being used in the project. Examples include the cost of lighting, heating, and cleaning the space where the project team works. Overhead does not vary with project work, so it is often considered a fixed cost.
- estimate—An assessment of the likely budget for a project. An estimate involves counting and costing and is based on ranges and probabilities. Throughout a project, managers and team members are asked to estimate remaining work, cost at completion, and required remaining time. An estimate is a forward projection, using what is known, to identify, as best as possible, the required effort, time, and/or cost for part or all of a project.
- general and administrative (G&A) overhead costs—The “indirect costs of running a business, such as IT support, accounting, and marketing” (Investing Answers n.d.).
- iterative estimating—A combination of top-down and bottom-up estimating, which involves constant refinement of the original estimate by taking into account information typically used in a top-down estimate (such as past history of similar projects) and increasingly detailed information generated by bottom-up estimating.
- parametric estimating—A way to use experience from parts of other projects to come up with estimates for work packages that are similar to past work but not the same.
- phase estimating—A type of iterative estimating that is “used when the project is large or lengthy or is developing something new or untried for the organization. In phased estimates, the near-term work is estimated with a high level of accuracy ±5 – 15% whereas future work is estimated at a high level with ±35% accuracy” (Goodrich n.d.). As the project advances through major phases, the budget for subsequent phases is intentionally reviewed and refined in light of knowledge gained to date.
- price—“A value that will purchase a finite quantity, weight, or other measure of a good or service” (Business Dictionary).
- Project Variation Request (PVR)—See Scope Change Request.
- Scope Change Request—A document that describes a proposed scope change, including its potential benefits and the consequences of not implementing the change. A Scope Change Request must be signed by all affected stakeholders prior to implementing a scope change. Also known as a Project Variation Request (PVR).
- scope creep—Changes to a project’s scope without any corresponding changes to the schedule or cost. The term is typically applied to changes that were unapproved or lacked sufficient knowledge about the project and potential assessment of risks and costs when they were approved. Simply put, scope creep is unmanaged change.
- scope evolution— An alteration to the project scope that occurs as the project participants learn more about the project. Scope evolution results in an official change in the project scope, and therefore to the project budget or schedule, as agreed to by all project participants. In other words, scope evolution is managed change.
- target value—The output stakeholders want the project to generate.
- target-value design—A design process that focuses on value as defined by the customer, with the project’s overall design involving stakeholder engagement and collaboration.
- top-down estimates—Estimates that “usually are derived from someone who uses experience and or information to determine the project duration and total cost. However, these estimates are sometimes made by top managers who have very little knowledge of the component activities used to complete the project” (Larson and Gray, 134). A top-down estimator generates a total for the entire project and then divides up that total among the various project tasks.
- value—“The inherent worth of a product as judged by the customer and reflected in its selling price and market demand” (Lean Enterprise Institute 2014).
