,Section A - Project Initiation AND Scope Definition
Q1.
A project manager is developing a cost-loaded schedule and must decide how to handle a
risk with a 30% probability of causing a 10-day delay and a 70% probability of no impact. If
the risk materializes, a mitigation strategy costing $15,000 can reduce the delay to 2 days.
The project's daily overhead is $2,000. Which option represents the optimal decision
based solely on expected monetary value (EMV) and schedule risk?
A. Do not implement mitigation; expected B. Implement mitigation; expected total cost
cost of risk is $6,000. is $18,000, which is less than the expected
delay cost without mitigation.
C. Implement mitigation only if the risk D. Do not implement mitigation; the
probability exceeds 50%. expected delay cost is $6,000, which is less
than the mitigation cost of $15,000.
Correct: D - Do not implement mitigation; the expected delay cost is $6,000, which is less
than the mitigation cost of $15,000.
Rationale:Without mitigation, expected delay cost = 0.30 * 10 * $2,000 = $6,000. With
mitigation, cost = $15,000 + 0.30 * 2 * $2,000 = $16,200. Since $6,000 < $16,200, not
implementing is optimal. Option A incorrectly omits the mitigation cost comparison; B
miscalculates the expected cost; C uses an arbitrary threshold not based on EMV.
Q2.
In a CPM network, activity X has a duration of 8 days and total float of 5 days. Its
successor Y has a free float of 3 days. If X is delayed by 4 days, which of the following
accurately describes the impact on the project and on Y's start?
A. Project delay of 0 days; Y's start delayed B. Project delay of 4 days; Y's start delayed
by 1 day. by 4 days.
C. Project delay of 0 days; Y's start delayed D. Project delay of 1 day; Y's start delayed
by 0 days. by 4 days.
Correct: A - Project delay of 0 days; Y's start delayed by 1 day.
Rationale:X has total float of 5 days, so a 4-day delay consumes only part of that float,
leaving 1 day of total float; hence project delay is 0. However, Y's free float is 3 days,
meaning Y can be delayed up to 3 days without affecting its successors. Since X's delay is 4
days, Y's early start is delayed by 4 - 3 = 1 day. Options B and D incorrectly treat total and
free float as the same; C ignores the free float constraint.

Q3.
A project manager is using a three-point estimate (PERT) for an activity: optimistic = 10
days, most likely = 14 days, pessimistic = 30 days. Which of the following is the correct
standard deviation of this activity's duration, and how would it be used in schedule risk
analysis?
A. Standard deviation = 3.33 days; it is used B. Standard deviation = 4.00 days; it is used
to calculate the variance of the critical path. to determine the probability of completing
the activity on time.
C. Standard deviation = 3.33 days; it is used D. Standard deviation = 4.00 days; it is used
to calculate the expected duration of the to calculate the contingency reserve for the
project. activity.
Correct: A - Standard deviation = 3.33 days; it is used to calculate the variance of the
critical path.
Rationale:PERT standard deviation = (P - O) / 6 = (30 - 10) / 6 = 3.33 days. This is used to
compute the variance of the critical path (sum of variances) to estimate project completion
probabilities. Option B gives the correct calculation but wrong application; C confuses
standard deviation with expected duration; D uses a different formula (P - O)/4, which is not
PERT.
Q4.
In a project with a deadline, the project manager must compress the schedule. Which of
the following techniques is most appropriate when the critical path has multiple activities
with varying costs to reduce duration, and the project has limited budget?
A. Fast tracking all critical path activities in B. Crashing the activity on the critical path
parallel, regardless of dependencies. with the lowest crash cost per unit time,
iteratively.
C. Adding resources to all non-critical D. Reducing the scope of non-critical
activities to increase their float. activities to free up resources for critical
ones.
Correct: B - Crashing the activity on the critical path with the lowest crash cost per unit
time, iteratively.
Rationale:Crashing involves adding resources to critical activities to reduce duration, and the
optimal approach is to crash the activity with the lowest crash cost per unit time first, then
re-evaluate the critical path. Fast tracking may not be feasible if dependencies are rigid, and
adding resources to non-critical activities does not shorten the project. Reducing scope is a
form of scope change, not schedule compression.
