If there are any common activities in both sequences, it will have a float of 0 since it is also on the critical path You can do this for all other sequences to determine floats for every activity. For example, in the diagram below, activities E, F, G, H, and I make up the cri...
Example 3: Critical Path Precedence Diagram The activity sequence that reflects the longest path across a project in the Precedence Diagram Method (PDM) is called the critical path. It establishes the quickest project duration feasible. The most important actions are those that have no float. The...
CPM works by creating a network diagram that shows the sequence of tasks in a project. Each task is assigned a duration and dependencies on other tasks. The critical path is the longest path through the network diagram, determining the project’s completion time. If any task on the critical ...
Using the network diagram, you can identify the longest path of any activity and the longest sequences. If you need to accelerate your project, you should reduce the time for critical path activities. If you have several critical paths, you will have a higher probability of the schedule chang...
Critical Path Method: a practical example If you have never used this methodology, let’s try to apply it to a simple example: imagine we have to install a shelf in the house. First, you need to split the project into phases:
We’ll use this critical path diagram to explain the elements that make up the critical path analysis process. To keep things simple, we’ve already done the calculations for this example using the CPM formula. The above critical path method example shows the critical path for getting a websi...
This activity network diagram shows three possible paths to do the project from start till completion. The green, yellow and red arrows indicate how the activities need to be sequenced in each respective path Example: MS Excel Spreadsheet for CP Method ...

What Is a Critical Path Template? A critical path template is an Excel document that has a network diagram, which shows the tasks as nodes or boxes. They’re connected by arrows that represent the dependencies between tasks. The arrows show the proper sequence of tasks and each task is assi...
Steps to Calculate the Critical Path for Efficient Planning STEP 1. Divide the Project into Tasks STEP 2. Order and Identify Dependencies STEP 3. Create the Network Diagram STEP 4. Estimate Duration STEP 5. Perform Resource Leveling STEP 6. Determine the Critical Path ...
