Respond to the following questions:
Determine the unconstrained critical path and its length (use days for Question 2, use weeks for question 3; use project days only, no weekends).
Determine the total hours and the hours per person required to complete the work?
Determine the total labor cost and the labor cost per person?
Prepare a Gantt chart illustrating the project length using constrained resource assignments and illustrating logical precedence diagramming for each activity (e.g., show finish-start relationships). Include color-coding by resource for each bar of the Gantt chart.
Develop a responsibility histogram for each resource over the length of the project and describe what adjustments, if any, were made to the project schedule to effectively deal with resource overloads or other schedule conflicts related to precedence (logic) requirements
Prepare a resourced-constrained (yet resource-leveled) critical path and its length.
Prepare a figure similar to Exhibit 9.9 (CPM) illustrating a cumulative cost curve.

Explanation / Answer
Q.2.
Critical Path - B-D-E-G-I and it takes 26 days.
b. Total hours and the hours per person required to complete the work-
Duration - (2+6+2+3+10+5+2+4+2) * 8 = 288 total hours
Hours of Alcides = (2+2+3+2+2) * 8 = 88 hours required to complete the work
Hours of Joan = (6+10+5+4) * 8 = 200 hours required to complete the work
c. Total labor cost and the labor cost per person
Total labor cost = (88 * 45) + (200 * 50) = $13,960
Labor cost of Alcides = 88 * 45 = $3,960
Labor cost of Joan = 200 * 50 = $10,000
