However, the convention is that we don’t write in the dependency type unless there’s an exception, such as an FF dependencies (i.e. Which tasks should happen immediately after this task. In this diagram, all the tasks are linked by means of FS dependencies. that sequence of activities that determines the overall duration of the project. In most of the examinations, it is asked by the teachers. The text next to the arrow, FS+10d, is made up as follows: FS means Finish to Start. If an activity of this path is delayed, the project will be delayed. To compute the critical path, you must first calculate how long each of the individual paths will take to complete. No highlighting is needed. It would not be unusual to see two tasks linked by a Start-to-Start dependency, where the lag is indicated as SS+50% (i.e., the second task should begin only once the first task is already halfway). Although many projects have only one critical path, some projects may have more than one critical paths depending on the flow logic used in the project. In this case, we’re allowing for 10d lag between D1 and D2. Video: Network diagrams: Critical path. Therefore, Path 3 is the PMP critical path of this network diagram.
