Module 24- Duration estimating

Question 1

Deterministic Estimate

Answer 1

Also called One point Estimate; appropriate when the activity durations are very predictable; requires that the team expert provide a reliable estimate of the time necessary to complete the activity. the expert provides a single estimate for an activity based on either his or her own knowledge or historical information.

Question 2

Triangular Distribution

Answer 2

“Simple average; Activity Duration=(O+M+P)/3
The simple average gives equal weight to all three estimates. In this case, the optimistic (O) and pessimistic (P) are treated equally with the most likely estimate (M).”

Question 3

Beta Distribution

Answer 3

optimistic+ 4 times the most likely +pessimistic / 6 Developed by PERT

Question 4

learning curves

Answer 4

suggests that as a person repeats a task, the time required to complete the task decreases.

Question 5

Standard deviation

Answer 5

a statistical measure of how much the actual activity duration is likely to vary.

Question 6

deterministic estimate

Answer 6

appropriate when the activity durations are very predictable;requires that the team expert provide a reliable estimate of the time necessary to complete the activity. This method is also called the one-point estimate method because the expert provides a single estimate for an activity based on either his or her own knowledge or historical information.

Question 7

Probabilistic estimate

Answer 7

used when there is uncertainty in how long an activity will take.

Question 8

Learning Curve

Answer 8

suggests that as a person repeats a task, the time required to complete the task decreases.
