CPE Project Planning & Scheduling Techniques 4

Question 1

Which probabilistic scheduling technique uses repeated simulations to model the range of possible project completion dates?

Accepted Answer

Monte Carlo Simulation

Answer

Monte Carlo Simulation runs thousands of iterations with varied activity durations to produce a probability distribution of project completion dates.

Question 2

In a Linear Scheduling Method (LSM) or Time-Chainage diagram, the slope of an activity line represents:

Accepted Answer

The production rate or velocity of the activity

Answer

The slope of a line in a time-chainage diagram represents the rate of production (e.g., meters per day), enabling planners to visualize crew movement along a linear project.

Question 3

In the context of schedule baseline management, what must occur before a schedule change is formally incorporated into the baseline?

Accepted Answer

Approval through the Integrated Change Control process

Answer

All changes to the schedule baseline must go through Integrated Change Control (ICC) to ensure changes are reviewed, approved, and documented.

Question 4

Which type of schedule reserve is held by the project manager to address identified risks?

Accepted Answer

Contingency Reserve

Answer

Contingency Reserve is allocated by the project manager for known-unknown risks identified during risk analysis, while Management Reserve is for unknown-unknowns.

Question 5

What is the primary benefit of using the Critical Chain Method (CCM) over CPM?

Accepted Answer

It addresses resource dependencies and student syndrome by using project and feeding buffers

Answer

CCM accounts for resource constraints and human behavior (Parkinson's Law, student syndrome) by removing individual task buffers and replacing them with project and feeding buffers.
