Chapter 10 Exercise 2. I need an unconstrained critical path and its length. (Just how to start?) I am confused

project management kloppenborg 4th ed

• Determine the unconstrained critical path and its length.
  • Note: Use days for Question 2 and 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 resource-constrained yet resource-leveled critical path.
• Prepare a figure similar to Exhibit 10.9 in the text, illustrating a cumulative cost curve

• 	Activity	Immediate Predecessor	Duration in Days	Resource	Hourly Costs	Work Hours per Day
  A	Evaluate Freezer		2	Alcides	$45	6
  B	Chart Temperature		6	Joan	$50	4
  C	Review Service Record		2	Alcides	$45	6
  D	Consult with HVAC Engineer	A, B, C	3	Alcides	$45	6
  E	Develop Construction Plan	D	10	Joan	$50	6
  F	Complete IC Assignment	E	2	Alcides	$45	2
  G	Complete ROI Analysis	E	5	Joan	$50	4
  H	Conduct Regulatory Review	E	4	Joan	$50	2
  I	Obtain Construction Approval	F, G, H	2	Alcides	$45	2
