Bob Heckman, manager of the MIS department at ASW Publishing, has received a request from Virginia Griner, the head of Human Resources, to develop an interactive icon- and menu-driven software package to be used by the benefits specialists in her department. Based on preliminary discussions with Virginia, Bob has identified two basically different types of functions that the package will have to serve, so he is planning on having it written in two modules. Based on this initial information, Bob has broken the project down into eight basic activities, listed in Table 1.1 along with their immediate predecessors and estimated times.
a. Draw the project network.
b. Determine the early and late start and finish times and the slack times for the activities. Identify the critical path. How long will the project take if there are no problems or resource limitations?
