Final answer:
MS Project records longer actual task durations without assumptions; users determine the cause, which could be delays, dependencies, or inefficiencies.
Step-by-step explanation:
When you enter an actual duration of a task in MS Project that is longer than the planned duration, MS Project does not automatically assume increased efficiency, overtime work, a delayed start, or a task dependency issue. Instead, it simply records the fact that the task took longer than initially planned. The user may then assess the reason for this discrepancy, which could be due to any number of factors, including a delayed start, unforeseen task dependencies, the need for overtime, or inefficiencies in the task completion process.
