The Critical Path Method determines the critical path for project, i.e. when it will be completed. The CPM also determines which activities make up the critical path – shorten the duration of critical-path activities and the project gets done sooner.
In order to prepare a critical path for a project, the following information must be put together –
- a list of the activities required to complete the project
- the estimated time required to complete each of the above activities
- for each activity, the preceding activities that must be finished before the activity-at-hand can start
