The High-Flight DC Graphic Novels special print production project. "Project: Retro" consisting of 13 activities, is described as follows:
a) prepare a network diagram for this project (use the AON format and calculate the ES, EF, LS and LF for each activity.
b) determine the critical path and project duration.
c) Calculate the free slack for each activity.
The table below show a set of activities of an IS project,its expected completion time (ET) and preceding activities.
