Ch 5 appendix And Ch 6

Question 1

True or false: in order to calculate the probability of finishing a project by it’s required completion time, It is necessary to have three time estimates for each activity and the required completion time for the project

Answer 1

True

Question 2

Give some examples of resources

Answer 2

People, equipment, machines, tools, facilities, and space

Question 3

Why do resources need to be considered when developing a schedule?

Answer 3

Because if sufficient resources are not available, some activities may have to be rescheduled for a later time when resources are available

Question 4

Describe how resources can be considered when creating a network diagram

Answer 4

If three resources are needed and are available simultaneously, the three activities can be performed simultaneously. However, if three resources are needed, but are available only sequentially, the three activities must be done sequentially. The diagram should be drawn to reflect these relationships

Question 5

What are technical constraints? Give some examples.

Answer 5

Technical constraints or activities that must be performed in a certain order to meet the project objective. For example, three house building activities- build foundation, build a frame and put on the roof- must be done in a sequence

Question 6

What are resource constraints? Give some examples.

Answer 6

Resource constraints are resources that are limited and available in a particular time frame. For example, if three rooms of a house need to be painted, but only one painter is available, the project is constrained by the personnel resource

Question 7

Describe what is meant by resource leveling or smoothing. why is it used? When is it used?

Answer 7

Resource leveling, or smoothing, is a method for developing a schedule that attempts to minimize the fluctuations and requirements for resources. This method levels the resources so that they are all applied as uniformly as possible without extending the project schedule beyond the required completion time. it is used when there’s variation in resource requirements among activities.

Question 8

Does resource leveling keep a project on schedule? If so, how?

Answer 8

Resource leveling only keeps the project on schedule because activities are delayed only to the point where all the positive Slack is used up, since any further delays would cause the project to extend beyond the project due date

Question 9

Describe what is meant by resource limited scheduling. Why it used? When is it used?

Answer 9

Resource limited scheduling is a method for developing the shortest schedule when the number or amount of available resources is fixed and cannot be exceeded. This method will extend the project completion time if necessary in order to keep within the resource limits.

Question 10

Does resource limited scheduling keep a project on schedule? If so, how?

Answer 10

Resource limited scheduling does not necessarily keep a project on schedule. It may extend the schedule in order to keep within the resource limits
