what is a critical path activity
What are critical path activities? Critical path activities are the project tasks that must start and finish on time to ensure that the project ends on schedule. A delay in any critical path activity will delay completion of the project, unless the project plan can be adjusted so that successor tasks finish more quickly than planned. You can choose between two options for identifying activities as critical: float and longest path. Float is a measure of schedule flexibility. P6 Web Access uses the Critical Path Method (CPM) to generate a project schedule.
