create network and a gantt chart for the paroject tasks

Final Exam

Question 1

Your team has been asked to test and document enhancements to a web application that allows buyers to purchase custom-printed canvas shoes. The tasks and dependencies are as follows:

  • Create a testing plan

Once the testing plan is ready, your team can:

  • Test the user interfaces
  • Test the database
  • Test the network
  • Write the documentation first draft

When the user interface tests are complete, you can:

  • Perform user testing—enlist some users to test the user interface

When the database and network testing are complete, you can:

  • Perform integration testing—network with the database

When the user testing of the user interface and the database testing are complete, you can:

  • Perform integration testing—database, network, and user interface

When all integration testing and user testing are complete, you can:

  • Perform system testing

Then you can:

  • Review and revise documentation

After all other tasks are complete, you can:

  • Obtain management approval

  • Create a network diagram and a Gantt chart for the project tasks. Ask your instructor if you are permitted to use software such as Microsoft Project to help you prepare your diagrams.
    • What is the planned duration for the testing project?
    • What is the critical path for the testing project?
    • For each task NOT on the critical path, calculate the amount of slack available.
    • If the user testing of the user interface takes 15 days, what will the impact be on the project duration?

Question 2

Wedding cost estimation: Given the following information, calculate the estimated costs for a wedding with 250 guests and a bridal party of six, using the methods indicated. Show your work.
Note that members of the bridal party are already counted as guests, you don’t need to add them twice.

  • Parametric estimate
  • Bottom-up estimate
  • Analogous cost estimate
  • You will probably notice some differences in the estimated values. Are these differences significant? What might cause the differences? If you were estimating a significant project in the future, which method(s) would you use and why?

Question 3

Cost reimbursable contract calculation.

  • A contract calls for a total payment of $800,000 with a guarantee. Essentially the contractor is guaranteed to make at least $200,000 above his costs. If the contractor can demonstrate his costs exceed $600,000, the project will pay the difference, with a $50,000 ceiling on the overage. The contractor demonstrates he spent $623,000. How much (gross) must the project remit to the contractor?
  • Another option for the same contract has the contractor guaranteed to be paid his costs plus 20%, for costs that exceed $600,000. With the same initial assumption—guarantee of $800,000 gross payment (no requirement to itemize costs), but if the contractor can show that costs exceed $600,000, the project will pay $800,000 plus the costs that exceed $600,000, plus 20% of those excess costs, with a ceiling of $900,000 gross. The contractor demonstrates he spent $623,000. How much (gross) must the project remit to the contractor?
  • Under option 3.2, at what dollar amount of total costs would the contractor be assuming all of the excess costs beyond that point?
  • In which option did the project assume more of the risk of a cost overrun? Explain.
