Late Finish Time (LF)

Late Finish Time (LF) is a term used in project management to refer to the latest possible time that a task can be completed. It is one of the key elements of Critical Path Method (CPM), which is a technique used to analyze and plan projects. The LF is determined by taking into account the duration of each task, the dependencies between tasks, and any external constraints that may affect the completion of the project.

Float/CPM

Float, also known as slack, is the amount of time that a task can be delayed without affecting the overall completion date of the project. Float is calculated by subtracting the Early Start (ES) and Late Start (LS) times from the Early Finish (EF) and Late Finish (LF) times respectively. CPM stands for Critical Path Method and it is a technique used to analyze and plan projects. It involves creating a network diagram that shows all of the tasks involved in a project and their dependencies on each other. The CPM then calculates the shortest path through this network, which is known as the critical path.

Conclusion

Late Finish Time (LF) is an important element of project management and it is used to determine when a task should be completed in order to meet deadlines. Float/CPM are two techniques used to analyze and plan projects, with float being used to calculate how much time a task can be delayed without affecting the overall completion date. By understanding these concepts, project managers can better manage their projects and ensure they are completed on time.
