PMI-SP Time Estimating & Resource Allocation 5

Question 1

Which estimating technique is MOST appropriate early in a project when detailed scope information is not yet available?

Accepted Answer

Analogous estimating

Answer

Analogous estimating uses expert judgment and historical data from similar projects, making it suitable when detailed information is limited in early phases.

Question 2

A project scheduler needs to assess schedule risk across multiple paths. Which technique uses duration probability distributions to simulate thousands of possible outcomes?

Accepted Answer

Monte Carlo simulation

Answer

Monte Carlo simulation runs thousands of iterations using statistical distributions of activity durations to produce a probability distribution of project completion dates.

Question 3

An activity requiring 160 hours of effort is assigned to two resources working in parallel at 100% capacity each. If each resource works 8 hours per day, what is the activity duration?

Accepted Answer

10 days

Answer

Two resources working in parallel provide 16 hours per day combined, so 160 hours / 16 hours per day = 10 days duration.

Question 4

What is the key difference between effort and duration in activity estimating?

Accepted Answer

Effort is the total work hours required; duration is the elapsed calendar time

Answer

Effort measures the total amount of work (person-hours) needed, while duration measures the calendar time from start to finish including non-working time.

Question 5

When applying the critical chain method, buffers are placed at the end of the project to protect which schedule element?

Accepted Answer

The project completion date

Answer

Critical chain adds a project buffer at the end of the critical chain to protect the project's final completion date from uncertainty in individual activities.
