In project management, what does lack of slack time signify for events on the critical path?

1. DELAY WILL EXTEND THE PROJECT END DATE

2. EVENTS CAN BE MOVED WITHOUT PENALTY

3. EVENTS ARE NON-ESSENTIAL FOR COMPLETION

4. DELAY CAN BE BUFFERED WITH EXCESS RESOURCES

The correct answer is: DELAY WILL EXTEND THE PROJECT END DATE

In project management, particularly when using the critical path method (CPM), the concept of slack time (or float) is essential for understanding project scheduling. A lack of slack time for events on the critical path indicates that these activities are crucial for the timely completion of the project. They are tightly scheduled, and any delays in these tasks cannot be absorbed without impacting the overall project timeline. When there is no slack time available, it means that the duration of those activities is fully committed, and any delay will directly lead to an extension of the project end date. This is because the critical path dictates the shortest time possible to complete the project; thus, each task on this path must be completed exactly as planned. If any event on this path is delayed, it delays the entire project. This principle is fundamental to effective project management, as it highlights the importance of monitoring tasks on the critical path closely and ensuring they are completed on time to avoid cascading delays throughout the project schedule. Consequently, while other non-critical tasks may have slack time that allows for flexibility and potential movement without impacting the overall timeline, tasks on the critical path do not enjoy this leeway. The other options reflect scenarios that apply to non-critical path activities or misunderstand the implications of slack
