How to calculate critical path manually

 · The Ultimate Guide to the Critical Path Method Step 1: Specify Each Activity. Using the work breakdown structure, you need to identify each activity (or task) involved Step 2: Establish Dependencies (Activity Sequence). Some activities will depend on .  · To calculate the critical path, the longest sequence of critical tasks, you first need to estimate the duration of each activity. To estimate the duration, try: Making educated guesses based on experience and knowledge. Estimating based on previous project .  · For you to find the critical path, you need to look for the longest sequence of important tasks. Finding the longest sequence of tasks also requires you to estimate the duration for each task.
