# Implications of Change and Expense Analysis using PERT

September 29, 2018

Scenario 3-412-a
McGee Carpet and Trim installs
carpets in commercial offices. Andrea McGee has been very concerned with
the amount of time it took to complete several recent jobs. Some of her
workers are very unreliable. A list of activities and their optimistic
completion time, the most likely completion time, and the pessimistic
completion time (all in days) for a new contract are provided in a given
table. Following are the activities that are required to install the
carpets in the offices: Activity 1 (Measure office room
dimensions),Activity 2 (Estimate cost), Activity 3 (Material
Requisition), Activity 4 (Workforce Requisition), Activity
5 (Special Tool Requisition),Activity 6 (Installation), Activity
7 (Inspection and customer acceptance).

Activity 2starts immediately after Activity 1. Activity 3, Activity
4, and Activity 5start concurrently after Activity
2. Activity 6does not start until after Activity 3, Activity
4,and Activity 5are completed. The carpet
installation project is complete after Activity 7 is
completed. If OT= Optimistic Time, MT= Most
Likely Time, and PT = Pessimistic Time, use Program Evaluation
Review Estimate (PERT) to compute the statistical time for each activity in the
table shown below.

Also, (a) Determine the expected
completion time and the variance for each activity (b) Determine the total
project completion time and the critical path for the project. (c)
Determine Early Start (ES), Early Finish (EF), Late Start (LS), and slack for
each activity. What is the probability that McGee Carpet and Trim
will finish the project in 40 days or less?

Define project management and
the necessary requirements.
Analyze implications of changes
in project scheduling.
Evaluate application of project
management techniques in terms of the firm’s business operational goals
and requirements.
