The Critical Path Method incorporates how many time estimates for activities__________________
Show answer Hide answer
Answer: A. one time estimate
Explanation
The standard Critical Path Method uses single-point deterministic time estimates for activities. Each activity is assigned one specific expected duration based on historical data or calculations. This deterministic approach distinguishes standard CPM from probabilistic scheduling methods. Critical Path Method determines the longest sequence of dependent tasks in a project network. Deterministic time estimates assume activity durations are known with reasonable certainty. Project scheduling algorithms calculate earliest and latest start times using these single estimates.
Construction scheduling software relies on deterministic CPM to establish baseline project deadlines. Project managers monitor critical path tasks closely to prevent overall project delivery delays. Single time estimates simplify schedule calculations for well-defined repetitive engineering tasks. Two time estimates are not used in standard Critical Path Method network calculations. Three time estimates are characteristic of PERT probabilistic scheduling rather than standard CPM. CPM requires valid time estimates to calculate critical paths and cannot operate with nil time.
