Critical Path Without Specialized Software
Manually identify the longest sequential task chain determining total project duration — delaying any one delays the whole delivery.
Goal
Distinguish tasks that can safely slip from tasks whose delay inevitably delays the entire project delivery.
Steps
-
1
List every project task with its estimated duration and any predecessor (must finish before it starts).
Expected Outcome
Immediate
You discover a task you considered secondary is actually on the critical path and deserves more attention immediately.
Evidence base
School: Critical Path Method / Operations Research
Founders: James Kelley · Morgan Walker (1957)
James Kelley and Morgan Walker developed the Critical Path Method (CPM) in 1957 at DuPont for plant maintenance scheduling; it became the foundation of modern project scheduling.
