REPRESENTATION OF LEAD Designed and Developed by https://www.pmbypm.com 4 B(S) = A(F) – 1d Example Duration of A = 3 Days, Duration of B = 2 Days, Duration of Lead = n Days (nD) The scheduled Start(S) of B is 1 day before (-1d) the scheduled Finish(F) of B Mathematical Network Diagram A B-nD FS-nD A B Bar Chart
- 5. LAG • The amount of time whereby a successor activity is required to be delayed with respect to a predecessor activity. • Example • A – Lay ceiling for Floor I, B – Construct Columns for Floor II. • A – Ship goods to a customer, B – Check if shipment has been delivered.
