Chapter 19, Problem 1CQ
A project has four activities that take 4, 3, 6, and 7 days, respectively. What is the total completion time for the project?
- a. 3 days, because this is the minimum time
- b. 7 days, because this is the maximum time
- c. 20 days, because this is the sum of the times
- d. It is not possible to determine the total completion time from the given information.
Expert Solution & Answer
Summary Introduction
To determine: The total completion time for the project.
Answer to Problem 1CQ
D. It is not possible to determine the total completion time from the given information.
Explanation of Solution
Given information:
Four activities of a project take 4, 3, 6 and 7 days respectively.
The given scenario lacks basic information to find the completion time of the project. Details like precedence relationship is not given which makes it impossible to find the sequence of activities in which the project must be done.

A project has 92 activities, but only 13 of them are analyzed here.
Activity P, 9 days, IP = not given
Activity W, 10 days, IP = not given
Activity S, 6 days, IP = not given
Activity A, 25 days, IP = P, W
Activity F, 24 days, IP W, S
Activity N, 21 days, IP S
Activity E, 28 days, IP = A
Activity M, 13 days, IP A, F
Activity B, 40 days, IP N
Activity H, 10 days, IP = E, M
Activity K, 14 days, IP = E, M, B
Activity D, 11 days, IP = B
Activity R, 10 days, IP = B
It has been calculated that LS(K) = 118, LS(D) = 109, LS(H) = 124, LS(R) = 116.

You are interested in completing your project as soon as possible. You have only one option. Suppose you could assign Employee A, currently assigned to activity G, to help Employee B, currently assigned to activity F. Each week that Employee A helps Employee B will result in activity G increasing its time by one week and activity F reducing its time by one week.

- John, Jack and Jill are project managers for Jusco Company. All three of them lead their own team, with two supervisors working under them. John’s team has 10 members, Jack has 8 members in his team and Jill has 11 members under his care. Both John and Jack completed their projects on time with the same amount of allocated budgets from top managers. But Jill didn’t manage to complete the project on time this time round. (i) Assuming all three projects have the same scale in terms of size, quality,and complexity, what can we conclude about the effectiveness and efficiency of these three project managers based on the informationabove?

- You are in charge of a project at the local community center. The center needs to remodel one of the rooms in time for the start of a new program. Delays in the project mean that the center must rent other space at a nearby church at additional cost. Time and cost data for your project are contained in the table. Your interest is in minimizing the cost of the project to the community center. a. Using the normal times for each activity, what is the earliest date you can complete the project? b. Suppose the variable overhead costs are $50 per day for your project. Also, suppose that the center must pay$40 per day for a temporary room on day 15 or beyond.
