Create a table and calculate the ES, EF, LS, and LF times and the slack for each activity in the figure below. Identify the critical path for the project. Can the project be completed in 30 weeks? How long will it take to complete? Assume that Systems Analysis actually finished at 8 weeks, Design Input & Output actually finished at 15 weeks, and Design Database actually finished at 19 weeks. Create another table and recalculate the expected project completion time. What is the new completion time? Which activities would you focus on to get the project back on schedule?
