Question

In PERT analysis, a critical activity has:

• A. Maximum float
• B. Zero float
• C. Maximum cost
• D. Minimum cost

Answer 1

Answer:

B. Zero float

Critical activity in PERT analysis has zero float and lies on the critical path. Float is the relaxation or delay provided to any activity. Total Float (TF) is the maximum delay, Free Float (FF) is the relax or delay without affecting EST (Earliest start time) of successor activity and Independent Float (IF) is relax or delay without affecting EST of successor activity and LFT (Latest Finish Time) of predecessor activity.
