1. Using a project start time of 0 (or January 1) and a required project completion time of 180 days (or June 30), calculate the ES, EF, LS, and LF times and total slack for each activity. If your calculations result in a project schedule with negative total slack, revise the project scope, activity estimated durations, and/or sequence or dependent relationships among activities to arrive at an acceptable baseline schedule for completing the project within 180 days (or by June 30). Describe the revisions you made.

Responses could be presented in a network diagram or in the schedule table format. The project should finish in 180 days. If the original plan is not completed by 180 days, the responses should describe what tasks were revised to meet the required completion date.

2. Determine the critical path and identify the activities that make up the critical path.

Responses can be presented in a list of activity names, highlighted in the network diagram, or highlighted in the schedule table.


You are required to make at least two comments on the responses posted by your classmates with a minimum of 50 words. Make sure you design your response with your own words. Your responses to your classmates must be of substance; not just “I agree” or “Good Post.” The purpose of the responses is to convert the discussion forum into a quality academic environment through which you improve your knowledge and understanding. Read and review all assigned course materials and chapters before you start working on your assignments.
