The primary computations for the scheduling variables would be as follows: ESB = EETJ + lag A - B - durationB = EFA + lag A - B - durationB EFB = EETJ + lag A - B = EFA + lag A - B LSB = LETN - lag B - C - durationB = LFC - lag B - C - durationB LFB = LETN - lag B - C = LFC - lag B - C.

The contract may state that the contractor is to make the request for payment by the 30th of each month and that payment will be made to the contractor by the 10th of the following month. Since the link lag value of E–H is 4, this is the number of days that Activity F could be shortened before this link lag value becomes 0. The least costly option is to shorten Activities B and C. Note that if only B or only C were to be shortened, the project duration would remain the same. As one reviewer, fromoz, noted on is Amazon review, it finally enabled him to "back my theoretical understanding with real life practical uses derived from the book.
