Calculating Float
Backward pass
Late finish (LF) Latest a task can finish Late start (LS) Latest a task can start LS = LF - duration + 1 Float: LS - ES or LF - EF
Work backward from end to begining
Forward pass
Early start (ES) Earliest a task can begin Early finish (EF) Earliest a task can finish EF = ES + duration - 1
Work from beginning to end
Schedule flexability
Monitor closely
Identify the critical path
Any change impacts the endpoint
Determines the project endpoint
Based on dependencies
Forward, backward, sideways
Conditions, branches, loopbacks
Allows for "What if?" analysis
