Task B and D I have completed and are correct. A1 and A2 are correct. I need help on the rest.

Introduction:

This task requires candidates to prepare a program evaluation and review technique (PERT) chart and apply critical path method (CPM) techniques.

Given:

Company A is installing a Web-based customer-feedback system to meet customer needs for quick response when rolling out new products. A new product line is rolling out in 34 weeks and the customer-feedback system must be installed and running in time for the new product launch.

Table 1.1 in the attached worksheet "PERT/CPM Tables" shows three estimates of the time it will take Company A to complete each of the activities and project tasks in the customer-feedback system project (optimistic, probable, pessimistic).

Company B is installing a similar feedback system to accompany a new product line and originally had the same time line as Company A. Company B just announced that its new product line is ahead of schedule and will be launched in 30 weeks instead of the initially projected 34 weeks. Because the Web-based customer feedback system must be installed and running in time for the revised date of the product launch, something must be done to shorten implementation time required for the customer-feedback system project. Refer to Table 1.2 in the attached worksheet "PERT/CPM Tables" that lists the expected time it will take to complete the activities if shortened as much as possible (crash time), the cost to complete the activity using normal resources (normal cost), and the cost of completing the activity on an accelerated basis (crash cost).

A. Prepare a PERT chart (network diagram) to identify the critical path for project completion.

1. Determine each of the following:

a. Expected duration of the entire project:

b. Slack for project task A:

c. Slack for project task H:

2. Determine the probability of completing this project in time for the product launch in 34 weeks:

B. Assume that Company B has the same expected completion times for project activities as Company A. Use your results from part A1 and the data in table 1.2 to determine the following:

Identify the following by using your results from part B:

1. Activities to be crashed in order to complete the project within 30 weeks:

2. Number of weeks each of these activities should be crashed to meet the deadline with the lowest possible increase in cost:

C. Determine the least increase in cost overall for crashing the project from 34 to 30 weeks:
