The critical path is the path in the project network diagram with the longest duration. In project management, a critical path is the sequence of project network activities which add up to the longest overall duration. This determines the shortest time possible to complete the project. Any delay of an activity on the critical path directly impacts the planned project completion date (i.e. there is no float on the critical path). In this instance path ACGIJ is the longest as it takes 23 days.

Answer options C and D are incorrect. These paths take 13 days.

Answer option A is incorrect. This path only takes 19 days.

An activity is an individual element of work that is logically linked to other activities to form the schedule. Its primary characteristics include an overall duration based upon the resources applied to it (manpower, material, and equipment), as well as a start and completion date that is tied to a work calendar. It also has a relationship with other activities (predecessors and successors).

Activity E has four days of float. The entire project will take 19 days to complete. Float, also called slack, is the amount of time an activity can be delayed without affecting any subsequent activities. There are two types of floats available: Free Float: It is the amount of time a schedule activity can be delayed without delaying the early start date of any immediately following schedule activities. Total Float: It is the total amount of time that a schedule activity may be delayed from its early start date without delaying the project finish date, or violating schedule constraint. Float is calculated by using the critical path method technique.

Answer option D is incorrect. Activity E is not on the critical path.

Answer options C and B are incorrect. These are incorrect calculations of the amount float available for Activity

E.
