Project Planning and Monitoring Schedule Management & Time Planning 1

Question 1

What does the Critical Path Method (CPM) determine in a project schedule?

Accepted Answer

The longest sequence of dependent activities that determines the minimum project duration

Answer

CPM identifies the longest path through the project network, which determines the earliest possible project completion date and shows which activities have zero float.

Question 2

In project scheduling, what is 'float' (also called slack)?

Accepted Answer

The amount of time an activity can be delayed without delaying the project end date

Answer

Float represents scheduling flexibility for a non-critical activity — it can be delayed by that amount without affecting the overall project completion date.

Question 3

Which scheduling tool displays project tasks as horizontal bars plotted against a timeline?

Accepted Answer

Gantt chart

Answer

A Gantt chart represents tasks as horizontal bars across a calendar timeline, making it easy to visualize durations, start/end dates, and task sequencing at a glance.

Question 4

What is a 'finish-to-start' dependency in project scheduling?

Accepted Answer

A successor activity can only start after the predecessor activity has finished

Answer

Finish-to-start is the most common dependency type, where the successor activity cannot begin until the predecessor activity is fully complete.

Question 5

Which duration estimation technique uses the formula (Optimistic + 4 × Most Likely + Pessimistic) ÷ 6?

Accepted Answer

PERT (Program Evaluation and Review Technique)

Answer

PERT applies a weighted average formula that gives four times the weight to the most likely estimate, producing an expected duration that accounts for uncertainty.
