Refer to Snapshot from Practice 6.1. Which of the following statements about the Yellow Sticky Approach is true?

ANSWER: All of these alternatives are correct. All of the yellow stickers are placed in easy view for all team members. This methodology sensitizes team members early to the interdependencies among activities of the project. This methodology empowers team members by giving them input to the important decisions that they must implement later. Small project networks are frequently developed using yellow Post-it® stickers.

Refer to Snapshot from Practice 6.2. Which of the following is not a reason why the critical path of a project is important?

ANSWER: All of these alternatives are reasons why the critical path of a project is important. The critical path helps you assign appropriate people to different tasks. The critical path helps you determine how to spend your time monitoring a project. The critical path helps you determine when it is appropriate to loan personnel to another project. The critical path helps you determine how to accelerate the completion of the project.

Draw a project network from the following information. What activity(s) is a burst activity? What activity(s) is a merge activity?What type of activity is each of the following?

Answer attached.

Refer to Snapshot from Practice 6.3. ________ has led to a dramatic increase in the speed in which new products are developed.

Concurrent engineering

All of the following are true of a hammock activity EXCEPT:

It is used to identify resources but does not use any.

Why is slack important to the project manager?

Slack is important to the project manager because it represents the degree of flexibility the project manager will have in rearranging work and resources. A project network with several near critical paths and hence, little slack, gives the project manager little flexibility in changing resources or rearranging work.

According to Snapshot from Practice 6.3, what is the driving force behind why companies have abandoned the sequential approach to product development and have adopted a concurrent engineering approach?

Speed to market

According to Snapshot from Practice 6.3, concurrent engineering, which has dramatically reduced the development time for new products, relies on what kind of lag?

Start-to-start.

All of the following statements about a WBS or project network are correct EXCEPT:

The WBS sets all project work, resource needs, and budgets into a sequential time frame.

How are WBS and project networks linked?

The network uses the time estimates found in the work packages of the WBS to develop the network. Remember, the time estimates, budgets, and resources required for a work package in the WBS are set in time frames, but without dates. The dates are computed after the network is developed.

K. Nelson, project manager of Print Software, Inc., wants you to prepare a project network; compute the early, late, and slack activity times; determine the planned project duration; and identify the critical activities. His assistant has collected the following information for the color printer drivers software project:

The project is expected to take 162 days. The critical activities are: A, D, G, I, J, K, L Early start for Activity E is: 10 Late finish for Activity F is: 100 Slack for Activity C is: 90

From the following information, develop an AON project network. Complete the forward and backward pass, compute activity slack, and identify the critical path. How many days will the project take?

The project will take 18 days. The critical path is A, B, C, E .The late start on Activity C is 10 days. The slack on Activity C is 0 days. The slack on Activity D is 1 days. The early start on Activity E is 14 days.

You are creating a customer database for the Hillsboro Hops minor league baseball team. Given the information below, complete the forward and backward pass, compute activity slack, and identify the critical path.

The project will take 24 days. The early start on Activity D is 6 days. The late start on Activity E is 10 days. The late finish on Activity I is 17 days. Calculate the free slack and total slack for all noncritical activities = There is no total slack and no free slack on any activity. How sensitive is the network schedule? Very sensitive. There are three paths that make up the critical path.

You have signed a contract to build a garage for the Simpsons. You will receive a $500 bonus for completing the project within 30 working days. The contract also contains a penalty clause in which you will lose $100 for each day the project takes longer than 30 working days. Given the information below, complete the forward and backward pass, compute activity slack, and identify the critical activities.

The project will take 32 days. The critical activities are A, B, C, D, H, J, K. The early start on Activity D is 13 days. The late start on Activity E is 17 days. The slack on Activity E is 4 days. The slack on Activity F is 1 days. Do you expect to receive a bonus or a penalty on this project? You will have to pay a penalty

The project information for the custom order project of the Air Control Company is presented here. Compute the early and late activity times and slack times. Identify the critical path. How many days will the project take?

The project will take 59 days. The critical activities are A, D, F, G, H. The late start on Activity C is 7 days. The slack on Activity C is 1 days. The slack on Activity D is 0 days. The early start on Activity E is 6 days.

All of the following are true of lags EXCEPT:

They are used to reduce free slack.

All of the following are true of free slack and total slack EXCEPT:

Total slack is the same as float

According to Snapshot from Practice 6.2, if the project schedule begins to slip, it is the ________ you should focus on to get the project back on schedule.

critical activities

According to Snapshot from Practice 6.2, the ________ is important because the activities on it impact project completion time.

critical path

According to Snapshot from Practice 6.2, when you have got money to spend to reduce risks, it usually gets spent on ________.

According to Snapshot from Practice 6.3, General Motors used the ________ approach to design the very first American hybrid car, the Chevy Volt.
