How are they linked?
An activity is an element in the project that consumes time, work packages from WBS are used to build activities found in the project network
Why bother creating a WBS?
Because WBS forces you to identify all tasks, deliverables, and rank in importance, they reinforce each other
Free Slack VS Total Slack
Free slack - the amount of time an activity can be delayed without delaying any immediate following activity total slack - how long it can be delayed without delaying the total project
Why are lags used in developing project networks?
It's the minimum amount of work time a dependent activity must be delayed to begin or end, and occurs with long duration activities, and constrain the start/finish of an activity
Why is slack important to project manager?
PM pay close attention to the critical path activities to make sure they are not delayed, slack tells us amount of time an activity can be delayed and not delay the project
WBS vs Project Network
