V. Reddy Dondeti, Professor School of Business - Norfolk State University BUS 476 Production/Operations Management Homework#7 Problem #1: The data related to the activities of a project are given in Table 1. Draw a project network, and do all your calculations for the Forward Pass and Backward Pass in the necessary Tables. Then show the values of LF, EF, and the slacks for the activities in a Table. Answer questions 1 through 25.
