Positive slack in PERT indicates

• A. Ahead of schedule
• B. Beyond of schedule
• C. As per schedule
• D. Critical Path

Answer 1

Answer:

A. Ahead of schedule

Positive slack indicates that the project is ahead of schedule and has excess resources. It is the difference between the latest allowable occurrence time and the earliest expected time. The equation for slack is Slack = TL - TE. When TL is greater than TE, the slack is positive. Zero slack means the project is on schedule, while negative slack indicates the project is behind schedule due to a lack of resources.
