Question 1

Planning must be done before performing any function. A schedule is a time-phased plan. The principal uses of schedules in the implementation process are outlined in the textbook. The list below contains items from the section entitled, During Project. One does not belong. Which one is incorrect?

Accepted Answer

Tracking expenses, both direct and indirect costs, is not a principal use of schedules during the project phase. It is an important function but not directly related to the use of schedules. The other items listed are valid uses of schedules during the project phase.

Question 2

Planning must be done before performing any function. A schedule is a time-phased plan. The principal uses of schedules in the implementation process are outlined in the textbook. The list below contains items from the section entitled, Before Starting Project. One does not belong. Which one is incorrect?

Accepted Answer

While a schedule does help to establish costs associated with manpower, materials, and machines, it does not specifically identify those expenses. Rather, cost estimates must be developed separately as part of the project planning process.

Question 3

ecause of its impact on the entire project, _____________ analysis is an important aspect of project planning.

Accepted Answer

Critical path analysis involves identifying the sequence of activities that must be completed on time for the entire project to be completed on schedule. This analysis allows project managers to determine the minimum amount of time needed to complete the project, identify potential bottlenecks, and prioritize activities accordingly. Therefore, critical path analysis is a crucial component of project planning. Financial, organizational, human resources, and performance analyses are also important aspects of project planning but may not have as direct an impact on the entire project as critical path analysis.

Question 4

___________ is described as follows: CPM is usually used for projects with predictable task times. CPM is a deterministic model that does not take into account variation in the completion time, so only one number is used for an activity's time estimate.

Accepted Answer

The description given specifically mentions that CPM involves estimating completion times for each activity, so the best choice is E. Choices A, B, C, and D are all related to other aspects of project management, and are not directly mentioned in the CPM description given.

Question 5

___________ is described as follows: Once the activities and their sequencing have been defined, the CPM diagram can be drawn.

Accepted Answer

The statement mentions drawing the CPM diagram, which is also known as the network diagram. Therefore, the best choice is A.

Question 6

The __________ is a robust logical system for planning and scheduling using bar charts. _____ is a graphical representation of the interrelationships of the various project activities. With _____ the contract administrator can assess the status of the project at any time, and it enables the contract administrator to monitor and revise scheduling during the project to meet the desired completion date.

Accepted Answer

The critical path method (CPM) is a widely used logical system for planning and scheduling using bar charts. CPM is a graphical representation of the interrelationships of the various project activities. With CPM, the contract administrator can assess the status of the project at any time, and it enables the contract administrator to monitor and revise scheduling during the project to meet the desired completion date. None of the other choices accurately describe the common system of planning and scheduling using bar charts.

Question 7

One of the tasks involved in a typical complex project is given below:CC charts or PAT grafts should be used to assess progress.

Accepted Answer

The statement seems to be referring to project management tools, but "CC charts" or "PAT grafts" are not recognized terms in project management for assessing progress. Common tools include Gantt charts, Critical Path Method (CPM), or Program Evaluation and Review Technique (PERT) charts.

Question 8

___________ is described as follows: The work breakdown structure, a listing can be made of all the activities in the project. This listing can be used as the basis for adding sequence and duration information in later steps.

Accepted Answer

The task of creating a work breakdown structure involves specifying each individual activity in the project. This listing will be later used to add sequence and duration information.

Question 9

___________ is/are identified as the longest-duration path through the network.

Accepted Answer

The longest-duration path through the network is known as the critical path. Therefore, the correct answer is option E - "The critical path".

Question 10

Progress curves are useful tools when a project is under way. Progress curves:
.Monitor progress. You can immediately see what should have been achieved at a point in time.
.Allow you to see how proactive action may keep the project on course.

Accepted Answer

The answer of Progress curves are useful tools when a...

Question 11

Planning must be done before performing any function. A schedule is a time-phased plan. The principal uses of schedules in the implementation process are outlined in the textbook. The list below contains some items which might have come from the section entitled, After Completion of Project. Which one(s) is/are correct?

Accepted Answer

The items listed relate to the benefits of schedules after the completion of the project. The schedule allows for a review and analysis of the actual project which can be used for improving future planning and estimating. Therefore, options A and C are correct while option B is not accurate as it refers to tracking budgeted expenses and not actual expenses. So, the best choice is "E" which includes options A and C only.

Question 12

S - earliest start time can be defined as:

Accepted Answer

The earliest start time is the earliest time at which the activity can start given that its precedent activities must be completed first. It takes into account the dependencies and sequencing of activities in a project.

Question 13

F - earliest finish time can be defines as:

Accepted Answer

Earliest finish time is equal to the earliest start time for the activity plus the time required to complete the activity.

Question 14

One of the tasks involved in a typical complex project is given below:
The master schedule is generally a logical network-type schedule that reflects perfect execution plans, the strategy, equipment delivery estimates, and engineering plans. Project milestones must be reviewed and assessed.

Accepted Answer

The task mentioned is true. The master schedule is an important part of a complex project that involves a logical network-type schedule, perfect execution plans, strategy, equipment delivery estimates, and engineering plans. It is essential to review and assess the project milestones to ensure the project is on track and progressing as planned.

Question 15

The critical path can be identified by determining the following four parameters for each activity:
.ES – earliest start time
.EF – earliest finish time
.LF – latest finish time
.LS – latest start time

Accepted Answer

The four parameters mentioned (S, F, LF, LS) are used to determine the critical path of an activity network.

Question 16

___________ is described as follows: Some activities are concurrent with other activities. A listing of the immediate predecessors of each activity is useful for constructing the CPM network diagram.

Accepted Answer

Sequencing the activities involves determining the order in which activities should be performed, including identifying which activities can be done concurrently and which are dependent on the completion of others. This is essential for constructing a CPM network diagram.

Question 17

The steps in the CPM project planning process are:
1.	Specify each individual activity.
2.	Sequence the activities.
3.	Draw a network diagram.
4.	Estimate the completion time for each activity.
5.	Identify the critical path (longest path through the network).
6.	Update the CPM diagram as the project progresses.

Accepted Answer

These are the correct steps in the CPM project planning process.

Question 18

Gantt charts (or Bar charts) are useful tools for planning and scheduling projects. Gantt charts:
.Allow you to assess how long a project should take.
.Lay out the order in which tasks need to be carried out.
.Help manage the dependencies between tasks.
.Determine the resources needed.

Accepted Answer

Gantt charts are indeed useful tools for planning and scheduling projects, and they allow for assessing project timelines, task order, task dependencies, and resource requirements.

Question 19

The CPM network consists of arcs and nodes. The ______ represent the actual activities while the ______ (events) represent when the activity starts and finishes.

Accepted Answer

In the Critical Path Method (CPM) network, the arcs represent the actual activities that need to be completed, and the nodes (events) represent the points in time when an activity starts or finishes.

Question 20

The CPM establishes:

Accepted Answer

The Critical Path Method (CPM) is a project management tool that helps to establish the quantity of work for each activity (A), the startup and sequence or order in which the work or the activity is to be done (B), and the rate at which the work will be performed to reach completion (C). Therefore, all of the statements A, B, and C are correct, making D the correct choice.
