What is the primary purpose of a business using Critical Path Analysis (CPA) during the planning phase of a large-scale construction project?

In a Critical Path Analysis network, if Activity C has an Earliest Start Time (EST) of 12 days and a duration of 5 days, and the succeeding Activity D has an EST of 20 days, what is the total float for Activity C?

Which of the following is a significant limitation of using Critical Path Analysis for a business entering a highly uncertain and dynamic global market?

Which of the following best describes an activity that lies on the critical path of a project network?

A project involves four sequential activities: A, B, C, and D.
- Activity A: duration 4 days, no predecessors.
- Activity B: duration 6 days, follows A.
- Activity C: duration 5 days, follows A.
- Activity D: duration 3 days, follows both B and C.

What is the Earliest Start Time (EST) for Activity D?

In a project network diagram, what is the meaning of the Earliest Start Time (EST) for a specific activity?

A project includes Activity C, which has a duration of 5 days. The Earliest Start Time (EST) for Activity C is day 8, and its Latest Finish Time (LFT) is day 15. Calculate the total float for Activity C.

In a complex network diagram, an activity has an EST of day 10 and an EFT (Earliest Finish Time) of day 14. Its LFT is day 18. Determine the duration of the activity and its Latest Start Time (LST), showing your working.
