Expert Guide to Critical Path Analysis
Introduction & Importance
Critical Path Analysis (CPA) is a project management technique used to determine the longest sequence of tasks that must be completed on time for a project to be finished on schedule. It’s crucial for identifying tasks that, if delayed, will delay the entire project.

Formula & Methodology
The critical path is the longest sequence of tasks from start to finish, calculated as:
Early Start (ES) = max(ES of predecessor, 0)
Early Finish (EF) = ES + duration
Late Start (LS) = min(Late Finish of successor, EF)
Late Finish (LF) = LS + duration
