7. Working out the critical path

In order to calculate the critical path the following must be done:

• Identify all of the activities for the whole project
• Prioritise the activities in order of importance
• Identify which activities must be completed before another one can begin
• Identify the Earliest Start Time (EST) for activities
• Identify the Latest Finish Time (LFT) for activities
• Identify the FLOAT - those tasks which can be completed outside the critical path
• Identify the critical path
