Question

The main difference between CPM and PERT is

a. ​the use of different activity time estimates.
b. ​PERT analysis is less expensive to conduct.
c. ​PERT lends itself to computerization while CPM networks must be constructed manually.
d. ​CPM integrates time and cost performance while PERT is based solely on time performance.

Answer 1

The correct answer is letter "A": ​the use of different activity time estimates.

Step-by-step explanation:

PERT (Project Evaluation Review Technique) and CPM (Corporate Performance Management) are both methods that allow managers to calculate the real-time it will take to finish a project. Though, PERT uses 3-time estimates for each activity while CPM requires only 1-time factors for each activity.
