The two main forms of float are free float and total float. Duration estimation can also accompany the creation of an activity network. 4 Creating an Activity Network Diagram. Pessimistic, Optimistic and Most likely estimates. The ability to determine total floats and the critical path for the as-built portion of a schedule (left of the data date) is solved by the graphical path method (GPM). The former is called “free float”, and the latter is called “total float”. In a small office construction project, the following activities are scheduled in sequence. The CPM method, also known as critical path analysis (CPA), consists in using the CPM formula and a network diagram to visually represent the task sequences of a project. 95. I'm also attaching a downloadable PDF file that illustrates the two concepts using a network diagram. It is like a built in safety. Here's a post explaining the difference between the two, with an example: Total Float vs Free Float. Negative float occurs in Primavera P6 when the total float is less than Zero, which means that the critical activities in the original plan (activity with zero total floats) are being delayed and the original project completion date is delayed.

Free Float (FF) = the maximum amount of time an activity can. The timeline for work can be postponed without impacting the program's deadline. The Backward Pass also establishes the total float in the network. It is the flexibility or buffer time available within an activity. There is no extra time to spare on these tasks, and if one is delayed, then the project is delayed too. To fix this issue, find the milestones that have late date less than the early dates and total float equal zero, and dissolve these milestones. Float = Slack, and Slack = Float. Zero float in project management is when there is no time between activities, tasks. Event slack is defined as the difference between the latest event and the earliest event times.
