1. Draw the project network diagram clearly showing the precedence structure of the various activities. (see below)

2. Compute the Early Start (ES), Early Finish (EF), Late Start (LS) and Late Finish (LF) times of each activity using the Critical Path Method (CPM) and identify the critical activities as well as the project completion time. (see below)

For example, Integrate Code (Task H) cannot start until the Web/Interface Development work for both Features 1 and 2 (1.e. Tasks D and G) is complete 3 For example, Feature 1 component duration can be reduced to 9 days if the component developer is authorized to work an equivalent of four workdays in overtime. However, the task cannot be shortened beyond 9 days
