OPERATIONS MANAGEMENT REDUCING PROJECT DURATION EXERCISE

Answer the following 10 questions based on the attached excel screenshot...

1. What is the precrash critical path of the project? Input the critical path activities in alphabetical order....example JLTZ.

2. What is the precrash project duration(weeks)?

3. What is the precrash project cost?

4. What is the cost slope for activity F?

5. Which task(s) would you shorten to reduce project duration by 1 week? If you chose to shorten a single task...input the task name. Example - G. If more than one task, input tasks in alphabetical order. Example...EQ.

6. What is the revised project cost?

7. Which task(s) would you shorten to reduce project duration by 1 more week? If you chose to shorten a single task...input the task name. Example - G. If more than one task, input tasks in alphabetical order. Example...EQ.

8. What is the revised project cost?

9. Which task(s) would youshorten to reduce project duration by 1 more week? If you chose to shorten a single task...input the task name. Example - G. If more than one task, input tasks in alphabetical order. Example...EQ.

10. What is project cost now?

\begin{tabular}{|c|c|c|} \hline 12 & E & 20 \\ \hline 0 & \multicolumn{2}{|c|}{ Task E} \\ \hline 12 & 8 & 20 \\ \hline \end{tabular} \begin{tabular}{|c|c|c|} \hline 20 & F & 24 \\ \hline 0 & \multicolumn{3}{|c|}{ Task F } \\ \hline 20 & 4 & 24 \\ \hline \end{tabular} Process to shorten project duration. 1. calculate the cost slope for each activity 2. identify the critical path or paths 3. shorten a critical path activity or activities with lowest cost slope by 1 time unit. Shortening a critical path activity or activities will also shorten project duration by 1 time unit - if done correctly. 4. regenerate the project network. Check that project duration declined by 1 time unit. Look to see if another critical path has emerged. 5. shorten again - yes then go to step 2 and repeat process. No then- finished
