Critical Path Analysis

Sequencing of activities and identifying dependencies

Critical Path Analysis (CPA) is a project management technique that requires mapping out every key task that is necessary to complete a project. Also known as the Critical Path Method, CPA is used to set a realistic deadline for a project and to track its progress along the way.

In project management, a critical path is the sequence of dependent tasks that form the longest duration, allowing you to determine the most efficient timeline possible to complete a project.

  • The KEY – Letter refers to project activity, e.g. P Preparatory Phase
  • Top number –  time (months) taken for that activity
  • Bottom number –  month number when activity ends, e.g. M lasts for two months and ends in Month 5.
