Part $3$

Remember the old saying, $$A project plan is not a schedule until resources are committed.$$

This exercise illustrates this subtle, but very important, difference.

Part A

Using your files from Part $2$ input resources and their costs if you have not already

done so$.$ All information is found in Tables A$2\mathrm{.}10$ and A$2\mathrm{.}11.$

Assembly$/$test R&D $(1$ team$)70$

Purchasing Procurement $(1$ team$)40$ Prepare a memo that addresses the following questions:

$1.$ Which if any of the resources are overallocated?

$2.$ Assume that the project is time constrained and try to resolve any overallocation

problems by leveling within slack. What happens?

$3.$ What is the impact of leveling within slack on the sensitivity of the network?

Include a Gantt chart with the schedule table after leveling within slack.

$4.$ Assume the project is resource constrained and resolve any overallocation

problems by leveling outside of slack. What happens? What are the managerial

implications?

$5.$ What options are available at this point in time?

Include a Gantt chart with the schedule table after leveling outside of slack.

Note: No splitting of activities is allowed.

Note: No partial assignments $($e$.$g$.,50$ percent$).$ All resources must be assigned $100$
