Problem #1 (8 points) 41 Given a table of activities associated with a project, their durations and preceding activities: activityDuration Precedes ol ne : A (start) 1 wks B,C D.E F.G 1 wk 3 wks 2 wks 1 wk 1 wk 2 wks 2 wks 2 wks (end) 2 points Draw an Activity on Nodes (AoN) diagram of the project, including activity durations. 2 points How many paths through the project exist? Identify the Critical Path by listing all critical activities in chronological order 2 points What is the project duration? -2 points What is the slack (in weeks) associated with any and all non-critical paths through the project? Identify the path by the activities listed in chronological order and fill in the associated slack. BONUS 3 points What activities, if any, can be delayed (and by how many weeks) without causing delays to either an overall project completion or any other activities?

Answer 1

PERT refers to Program evaluation and review technique where networks are used to plan and control the project and CPM refers to critical path method where shortest path is taken to plan the project. The objectives of PERT/ CPM are: -

• Plan is made visually that help the project team to understand the progress and direction.
• Project completion time can be determined.
• Brainstorming what needs to be done.
• To identify the task that require tight control.
• To identify task that is critical for completion time.
