Chapter 5 Estimating Project Times and Costs 163
management estimate; this represented about a 20 percent overrun! Furthermore, the
bottom-up time estimate based on the project network was four months longer than the
top management time estimate. Another meeting was scheduled with the significant
stakeholders to check the estimates and to brainstorm for alternative solutions. At this
meeting everyone agreed the bottom-up cost and time estimates appeared to be accurate. Following are some of the suggestions from the brainstorming session.
∙ Change scope.
∙ Outsource technology design.
∙ Use the priority matrix (found in Chapter 4) to get top management to clarify their
∙ Partner with another organization or build a research consortium to share costs and
to share the newly developed technology and production methods.
∙ Cancel the project.
∙ Commission a break-even study for the laser printer.
Very little in the way of concrete savings was identified, although there was consensus that time could be compressed to the market launch date, but at additional costs.
Lauren met with the marketing (Connor), production (Kim), and design (Gage)
managers, who yielded some ideas for cutting costs, but nothing significant enough to
have a large impact. Gage remarked, “I wouldn’t want to be the one to deliver the message to top management that their cost estimate is $1,250,000 off! Good luck, Lauren.”
1. At this point, what would you do if you were the project manager?
2. Was top management acting correctly in developing an estimate?
3. What estimating techniques should be used for a mission-critical project such as this?
Josh and Mike met as roommates during freshman year at Macalester College in St. Paul,
Minnesota. Despite a rocky start they became best friends. They are planning a two-week
adventure together to celebrate their graduation in June. Josh has never been to Europe
and wants to visit France or Spain. Mike spent a semester abroad in Aarhus, Denmark,
and traveled extensively in northern Europe. Even though Mike has never been to France
or Spain, he wants to go to someplace more exotic, like South Africa or Vietnam. For the
past week they have been arguing over where they should go. Josh argues that it will cost
too much to fly to South Africa or Vietnam, while Mike counters that it will be much
cheaper to travel in Vietnam or South Africa once they are there. They agree that they
can spend no more than $3,500 each on the trip and could be gone for only two weeks.
One evening when they were arguing with each other over beers with friends, Sara
said, “Why don’t you use what you learned in your project management class to decide
what to do?” Josh and Mike looked at each other and agreed that made perfect sense.
1. Assume you are either Mike or Josh; how would you go about making a decision
using project management methodology?
2. Looking first at only cost, what decision would you make?
3. After cost, what other factors should be considered before making a decision?

A5-1 Use learning curves to improve task estimates.
Learning Curves for Estimating
Use learning curves to
improve task estimates.
A forecast estimate of the time required to perform a work package or task is a basic
necessity for scheduling the project. In some cases the manager simply uses judgment and
past experience to estimate work package time or uses historical records of similar tasks.
Most managers and workers intuitively know that improvement in the amount of
time required to perform a task or group of tasks occurs with repetition. A worker can
perform a task better/quicker the second time and each succeeding time she performs
it (without any technological change). It is this pattern of improvement that is important to the project manager and project scheduler.
This improvement from repetition generally results in a reduction of labor hours for
the accomplishment of tasks and results in lower project costs. From empirical evidence across all industries, the pattern of this improvement has been quantified in the
learning curve (also known as improvement curve, experience curve, and industrial
progress curve), which is described by the following relationship:
Each time the output quantity doubles, the unit labor hours are reduced at a constant rate.
For example, assume that a manufacturer has a new contract for 16 prototype units
and a total of 800 labor hours were required for the first unit. Past experience has
indicated that on similar types of units the improvement rate has been 80 percent. This
relationship of improvement in labor hours is shown below:
800 × .80 =
640 × .80 =
512 × .80 =
410 × .80 =
By using Table A5.1 unit values, similar labor hours per unit can be determined. Looking across the 16 unit level and down the 80 percent column, we find a ratio of .4096. By
multiplying this ratio times the labor hours for the first unit, we obtain the per unit value:
.4096 × 800 = 328 hours, or 327.68
That is, the 16th unit should require close to 328 labor hours, assuming an 80 percent
Obviously a project manager may need more than a single unit value for estimating
the time for some work packages. The cumulative values in Table A5.2 provide factors
for computing the cumulative total labor hours of all units. In the previous example,
for the first 16 units, the total labor hours required would be
800 × 8.920 = 7,136 hours
