Duration Estimation Methods	• Past experience • Expert opinion • Mathematical derivation – Beta distribution – Most likely (m) – Most pessimistic (b) – Most optimistic (a)
Constructing the Critical Path	• Forward pass – an additive move through the network from start to finish • Backward pass – a subtractive move through the network from finish to start • Critical path – the longest path from end to end which determines the shortest project length
Rules for Forward pass	Forward Pass Rules (ES & EF) – ES + Duration = EF – EF of predecessor = ES of successor – Largest preceding EF at a merge point becomes EF for successor
Rules for Backward Pass	Backward Pass Rules (LS & LF) – LF – Duration = LS – LS of successor = LF of predecessor – Smallest succeeding LS at a burst point becomes LF for predecessor
Reducing the Critical Path	• Eliminate tasks on the CP • Convert serial paths to parallel when possible • Overlap sequential tasks • Shorten the duration on critical path tasks • Shorten – early tasks – longest tasks – easiest tasks – tasks that cost the least to speed up
