- Prepare a plan for a small project of moderate complexity (at least 12 activities, with some interdependencies between activities). Your plan should identify the activity by their beginning and ending nodes and by short, descriptive titles. Estimate the times to complete the activities. Prepare a PERT/CPM network. Determine critical path and the expected time for completing the project (Activity Analysis and Event Analysis). Choose a project of some personal interest and knowledge (e.g. building a house, selling a house, political campaign etc.) Your project will be judged by how completely it identifies all activities, the reasonableness of your time estimates and the correctness of your analysis.
