What is the difference between crashing and fast-tracking in PMP?

Crashing adds additional resources to critical path activities to reduce duration, which increases cost. Fast-tracking performs sequential activities in parallel, which is free but increases the risk of rework and errors.

How do you identify the critical path in a project schedule?

The critical path is the longest sequence of dependent activities with zero total float. It determines the shortest possible project duration. Use forward pass (ES/EF) and backward pass (LS/LF) calculations to identify all activities with zero float.

When should you use schedule compression techniques?

Use schedule compression when the project is behind schedule and the sponsor or constraints require the original completion date. Always analyze the critical path first — compressing non-critical activities does not shorten the project.

What is management reserve and how is it used in PMP?

Management reserve is a buffer controlled by the project manager (or sponsor) for unknown-unknowns. It is not part of the cost baseline. It can be used for schedule compression costs like crashing, subject to sponsor approval.

Critical Path Method and Schedule Compression Techniques for PMP

Scenario

Your construction project has a planned duration of 18 months. After a 3-week delay in the foundation phase, the sponsor demands the original completion date be preserved. The critical path runs through foundation → structure → MEP → finishing. You have $200,000 in management reserve. What schedule compression technique should you evaluate first, and what are the trade-offs?
