CST Time Management & Resource Allocation 4

Question 1

A project schedule shows a Schedule Performance Index (SPI) of 0.75. This means the project is:

Accepted Answer

25% behind schedule — only 75 cents of work done per $1 planned

Answer

SPI = EV / PV; an SPI of 0.75 means only 75% of the planned work has been earned, indicating the project is behind schedule.

Question 2

In resource allocation, 'leveling' differs from 'smoothing' primarily because leveling:

Accepted Answer

May extend the project end date to resolve overallocations

Answer

Resource leveling may change the project end date by delaying activities beyond their float, whereas smoothing respects the current end date.

Question 3

A scheduler is managing a project where one activity has a total float of -5 days. The MOST appropriate immediate response is to:

Accepted Answer

Compress the schedule through crashing or fast-tracking to eliminate the negative float

Answer

Negative float indicates the project end date will be missed; schedule compression techniques must be applied to recover the lost time.

Question 4

What is the primary purpose of a resource breakdown structure (RBS) in project scheduling?

Accepted Answer

To categorize and organize project resources by type and category

Answer

The RBS is a hierarchical structure that organizes resources by category and type, facilitating resource planning and allocation.

Question 5

Which scheduling technique uses three-point estimates and calculates the standard deviation of the critical path to predict schedule risk?

Accepted Answer

PERT analysis

Answer

PERT uses optimistic, pessimistic, and most likely estimates to calculate expected durations and uses standard deviation to quantify schedule uncertainty.
