In a project network, a delay in an activity that has a total float of 6 days is 4 days. Assuming no other change, what is the effect on the project completion date?

The project completion date is unchanged because total float of 6 days can absorb the 4-day delay. Only the delay exceeding the float would push out the project end date, and here the activity merely uses up 4 days of its float.

  1. AThe project is delayed by 4 days
  2. BThe project is delayed by 2 days
  3. CThe project completion date is unchangedCorrect
  4. DThe project is delayed by 6 days

Explanation

Total float is the delay an activity can absorb without delaying project completion. A 4-day delay is less than the 6-day float, so the project end date does not change. The remaining float falls to 2 days. Option 'delayed by 2 days' wrongly subtracts float from the delay.
