WGU Project Management C722: Comprehensive Guide to Unit 7,
Modules 23 & 24
Project management often uses the term ________ to describe the number of time periods required to
complete some portion of the work.
a. resource estimation
b. duration
c. project schedule - correct answer ✔✔b. duration
Duration is used to describe the number of time periods required to complete a portion of the work.
Because the activity durations will be integrated with the activity sequencing to become the approved
schedule, who should have primary input into the duration estimates?
a. The project manager
b. Stakeholders
c. The project sponsor
d. The team member doing the work - correct answer ✔✔d. the team member doing the work
The team member doing the work will have a better idea of how long an activity should take.
The problem with using the _______ estimation method is that the people providing the estimate can be
too optimistic or too pessimistic, which results in unreliable duration estimates.
a. probabilistic
b. deterministic
c. triangular - correct answer ✔✔b. deterministic
, Deterministic estimation relies on one-point estimating, so it is dependent on the expertise of the person
providing the estimate rather than on multiple inputs.
You are your own project manager for a renovation project on your kitchen. Your contractors have given
you the following duration estimates for the work that needs to be done:
Optimistic Estimate = 12 days
Most Likely Estimate = 22 days
Pessimistic Estimate = 40 days
What is the simple average (rounded to the nearest day)?
a. 25 days
b. 23 days
c. 22 days
d. 28 days - correct answer ✔✔a. 25 days
Using the formula (O + M + P)/3, the simple average is 24.7 days, rounded up to 25.
What is the weighted average or beta distribution method estimate of duration (rounded to the nearest
day)?
Optimistic Estimate = 12 days
Most Likely Estimate = 22 days
Pessimistic Estimate = 40 days
What is the simple average (rounded to the nearest day)?
a.22 days
b. 25 days
