IFC Project Planning & Scheduling 1 — Questions and Answers
Question 1: What is the purpose of a project work breakdown structure?
- To decompose the project into manageable, defined work packages (Correct answer)
- To list all project team members
- To create the project budget
- To schedule all project meetings
Correct answer: To decompose the project into manageable, defined work packages
A work breakdown structure decomposes the project into manageable work packages, enabling accurate estimation, assignment, and tracking of all project work.
Question 2: Which scheduling method identifies the longest path through a project?
- Critical Path Method determines the minimum project duration (Correct answer)
- Gantt chart visual representation
- Simple task listing
- Calendar-based scheduling
Correct answer: Critical Path Method determines the minimum project duration
The Critical Path Method identifies the longest sequence of dependent tasks, determining the minimum project duration and highlighting tasks that cannot be delayed.
Question 3: What factor most commonly causes project cost overruns?
- Inadequate scope definition and uncontrolled scope changes (Correct answer)
- High material costs
- Bad weather
- Equipment failure
Correct answer: Inadequate scope definition and uncontrolled scope changes
Inadequate scope definition and uncontrolled scope changes (scope creep) are the most common causes of cost overruns, as they add work beyond original estimates.
Question 4: How should project risks be incorporated into scheduling?
- By adding contingency time to critical activities and overall project duration (Correct answer)
- By ignoring risks to maintain aggressive schedules
- By adding contingency only to the final milestone
- Risks should not affect the schedule
Correct answer: By adding contingency time to critical activities and overall project duration
Incorporating contingency time for critical activities accounts for the impact of potential risks, creating more realistic and achievable project schedules.
Question 5: What is earned value management?
- A method to measure project performance by comparing planned versus actual progress and cost (Correct answer)
- A way to calculate employee bonuses
- A pricing strategy for services
- A method for tracking material deliveries
Correct answer: A method to measure project performance by comparing planned versus actual progress and cost
Earned value management integrates scope, schedule, and cost metrics to objectively measure project performance and predict future trends.
Question 6: Why is stakeholder communication important in project management?
- It ensures expectations are managed and decisions are informed and timely (Correct answer)
- It is only required at project start and completion
- It delays decision-making
- It is only important for large projects
Correct answer: It ensures expectations are managed and decisions are informed and timely
Regular stakeholder communication manages expectations, enables informed decision-making, and builds support for the project throughout its lifecycle.
