Question 7

A project manager ascertained that five different resources are needed to complete a project that has been estimated to last 37 days. Just to be on the safe side, the project manager told the client that the project would definitely be delivered in 40 days and 40 nights and arranged to rent the resources for that period of time. The project manager goes to the local rental center at the start of day 1 of the project, signs a 40-day lease agreement for all five resources, and brings them to the site to begin the project. Analyze the Gantt chart and resource list (activity durations are in parenthesis) and determine how much money is being wasted with this rental plan. If each resource could be rented for just the time it takes to complete each activity, what would the charge to the project be?

Accepted Answer

The project manager has paid for 40 days

Question 8

The heir to the throne was due 60 days from now and the first-time father had a serious construction project on his hands converting his man cave into a nursery. The seven activities, their normal and expedited times (in days) and costs appear in the table. Just to be on the safe side, he decided to bring the project in at 53 days in case the delivery was a week early. Tell him what the least expensive 53-day project is; which activities should be reduced in duration, by how many days, and at the total cost, so he can roll up the sleeves on his "World's Greatest Dad" sweatshirt, and get to work.

Accepted Answer

The project before any expediting takes

B)  Resource 2 
C)  Resource 3 
D)  Resource 5

C)  Resource 3 
D)  Resource 5

Question 10

AON networks have an advantage over AOA networks:

Accepted Answer

A)  If the project under study is complex. 
B)  Because they don't need dummy activities. 
C)  In the construction industry because they are the norm. 
D)  When it is critical to highlight milestones. 
A)  If the project under study is complex. 
B)  Because they don't need dummy activities. 
C)  In the construction industry because they are the norm. 
D)  When it is critical to highlight milestones.

Question 11

What are four criticisms and caveats to bear in mind as you develop a project activity network?

Accepted Answer

There are several criticisms and caveats

Question 12

Crashing costs for a project are governed by the function:
50t2 + 100t
where t represents the number of days crashed (see graph). The project manager wants to crash the project, and is willing to pay up to $1,000 per day saved. How many days can be saved before the per-day cost is too high?

Accepted Answer

We can crash the project to the point wh

Question 13

A project has the activity duration and cost information indicated in the table where all times are in weeks. What is the lowest total cost for completing this project in 33 weeks?

Accepted Answer

$12,250 is the least expensive 33 week p

Question 14

What is the minimum cost completion time for this project if the activities have normal and crash costs as indicated and there is a $1,000 fixed cost for each day on site plus a $500 penalty for each activity that is crashed? The crash costs represent the cost of a fully expedited activity. For example, reducing activity Y from 13 days to 12 days costs an extra $100 on top of the $500 expediting cost for a total cost of $2,600. Reducing Y from 13 days to 10 days costs an extra $300 on top of the $500 expediting cost, for a total activity cost of $2,800.

Accepted Answer

The project before any expediting takes

Question 15

A project has the activity duration and cost information indicated in the table where all times are in weeks. There is a penalty of $4,000 per week for every week the project exceeds 37 weeks. What is the lowest total cost for completing this project?

B)  $184,000 
C)  $187,000 
D)  $192,500 
A)  $172,000

D)  Can have all of the features described in A-C above.

Question 17

AOA networks have an advantage over AON networks:

Accepted Answer

A)  If the project is complex. 
B)  Because they are easier to read for novices. 
C)  When it comes to software packages for project management. 
D)  When the task of network labeling is considered.
