Project scheduling: interpretation of negative slack/float When an activity shows negative slack (negative float) in a network schedule, what does it indicate for the overall program status and resources? Choose the most accurate statement.

Difficulty: Easy

Correct Answer: The programme is behind schedule and additional resources are required to finish on time

Explanation:

Concept
Slack (float) is the allowable delay of an activity without affecting project dates. Negative slack means the required finish date is earlier than the earliest achievable finish—indicating the schedule is already behind.


Implications
Negative float typically requires acceleration measures (e.g., crashing, fast-tracking, or allocating more resources) to meet deadlines.


Final Answer
The programme is behind schedule and additional resources are required to finish on time
