What is the critical path in project management?
In project management, a critical path is the sequence of project network activities which add up to the longest overall duration, regardless if that longest duration has float or not. This determines the shortest time possible to complete the project.
Calculating the Length of Your Project. In project management, a critical path is the sequence of project activities that add up to the longest overall duration. This determines the shortest time possible to complete the project. Also, you determine the approximate start time for each task on the critical path.
- The project duration is the basic project management characteristic that is usually expressed in terms of working time units (hours, days, weeks, months, years). For example, a project's duration can be equal to 40 hours, or 5 days, or 1 workweek.
- In the project management world, critical tasks are the jobs your team must complete to finish a project. The critical path is the sequence of critical tasks, identifying which order to complete them and how long each task will take. The length of the critical path tells you the timeline for completing your project.

There are six steps in the critical path method:
- Step 1: Specify Each Activity.
- Step 2: Establish Dependencies (Activity Sequence)
- Step 3: Draw the Network Diagram.
- Step 4: Estimate Activity Completion Time.
- Step 5: Identify the Critical Path.
- Step 6: Update the Critical Path Diagram to Show Progress.
- Highlight the critical path
- Click the View tab.
- In the Task Views group, click the arrow beneath Gantt Chart, and then click More Views.
- In the More Views dialog box, in the Views list, select Detail Gantt, and then click Apply. By default, the critical task Gantt bars and link lines are red.
- In project management, float or slack is the amount of time that a task in a project network can be delayed without causing a delay to: subsequent tasks ("free float") project completion date ("total float").
- PERT is a method used to analyze project tasks and time needed to complete them. Also, each task has three time estimates: optimistic time, normal time and pessimistic time estimate. The optimistic time is the fastest possible time needed to complete the task and usually involves additional cost.
The critical path method (CPM) is a step-by-step project management technique for process planning that defines critical and non-critical tasks with the goal of preventing time-frame problems and process bottlenecks. Determine the expected completion or execution time for each task.
- The Certified Public Manager₢ (CPM) is a United States professional designation established in 1979 for the purpose of improving performance and advancing best practice standards for public sector managers. The CPM is a comprehensive management development program based upon a selected set of competencies.
- They can be different based on its predecessor and/or successor activity relationships. By definition: Total Float (TF) = the maximum amount of time an activity can be delayed from its early start without delaying the entire project.
- A work-breakdown structure (WBS) in project management and systems engineering, is a deliverable-oriented breakdown of a project into smaller components. A work breakdown structure is a key project deliverable that organizes the team's work into manageable sections.
