Critical Path Analysis Practice
Practise CPA by filling in the EST and LFT directly on the network diagram. Change the level below before starting a new question.
Easy
The durations are already shown on the paths. Students work out the EST, LFT and critical path.
Hard
The durations are hidden. Students must use the task table and type the duration values onto the paths before working out EST, LFT and the critical path.
Mode: Easy
Project
Fill in the diagram directly.
Project duration: ?
Hint: Start at node 1 with 0 and work forwards first.
Task Table
All scenarios are linked to business projects. In Hard mode, use this table to work out the durations and type them onto the paths.
Critical Path
Enter like A-B-D-F
Score
–
Project duration
?
Total Float
Float = LFT of end node − EST of start node − Duration. Enter 0 for critical activities.
