	Critical activities don’t have float, or have zero float, which means that they cannot be delayed. This sequence of tasks creates the critical path. The ‘’’total float’’’ can be calculated by the formula: Latest Start (LS) - Early Start (ES).		Critical activities don’t have float, or have zero float, which means that they cannot be delayed.

	Identifying the float is beneficial to project managers because it helps understand in which activities, they must focus the resources on, and which ones can be delayed (if necessary) in order to complete the project on time.

			Nowadays, it is one of the most popular project management tools as it is even more accessible to project managers thanks to the numerous software tools that have been created over the years to construct and manage them.

	One of the benefits of using this tool is that allows to identify the most critical activities of the project. Moreover, if one of these is delayed, the project itself is compromised. Thus, it helps project managers to have a good overview in which task they must put more focus on. Nonetheless, CPM also has its limitations. In this article these disadvantages will be described and how to deal with them will be explained.

	The final step is to calculate the float of each activity. This will help to identify how much a specific task can be delayed without delaying the final date of the project. In other words, it shows the flexibility that the project has.		The final step is to calculate the float of each activity.
