Critical Path Estimator
Estimate critical path duration and potential schedule compression gains.
Critical Path Estimator identifies the dependency chain that determines total project duration. In project scheduling, the critical path is the longest sequence of dependent tasks from start to finish; if any task on that path slips, the project end date usually slips as well. Slack or float is the amount of time a noncritical task can move without changing the final date. Parallel work can shorten schedules only when dependencies allow it, while buffers absorb uncertainty from testing, review, handoffs, and rework. This tool is useful for rough delivery planning and explaining schedule risk, but real critical-path analysis should include all dependencies, resource constraints, calendars, external approvals, and changing scope.
