Question 1

It is common to progressively elaborate the network diagram

Accepted Answer

Progressive elaboration is a project management approach where the project team continuously updates and improves project deliverables as more information becomes available. In the case of network diagrams, it is natural to start with a high-level overview at the beginning of the project and then add more detail as the project progresses and more information becomes known or clear. Therefore, the best choice is C.

Question 2

The responsibility assignment matrix may use a P to designate ____ responsibility and an S to indicate ____ responsibility for a specific work item.

Accepted Answer

The responsibility assignment matrix typically uses a P to designate primary responsibility and an S to indicate support responsibility for a specific work item. This makes Choice A the correct answer. Choice B is incorrect as permanent and sometimes are not typically used to describe responsibilities in a responsibility assignment matrix. Choice C is also incorrect as personnel and supply do not accurately describe different levels of responsibility. Choice D is partially correct as primary is used in the responsibility assignment matrix, however, secondary is not typically used to describe responsibilities.

Question 3

The ____ shows all the individuals associated with each work item in the work breakdown structure, as well as all the work items associated with each individual.

Accepted Answer

The responsibility assignment matrix (RAM) shows all the individuals associated with each work item in the work breakdown structure, as well as all the work items associated with each individual. It is commonly used in project management to clarify who is responsible for what tasks and to ensure clear communication and accountability within a project team. The network diagram is a visual representation of project tasks and their dependencies, while the work breakdown structure is a hierarchical breakdown of the project deliverables and tasks. The project scope document defines the project's objectives, scope, and boundaries.

Question 4

An activity in a network diagram cannot start until

Accepted Answer

An activity in a network diagram cannot start until all of the preceding activities that are linked to it by arrows are finished. This is because the arrows represent dependencies between activities, indicating that one activity must be completed before the next one can begin. Therefore, in order for an activity to start, all of the activities that it depends on must be finished.

Question 5

Standard subnetworks should be developed for those portions of projects for which

Accepted Answer

Standard subnetworks should be developed for those portions of projects for which the logical relationships among the activities have been well established through historical practice. This will help to streamline the planning process and ensure consistency across projects. Repeat once or twice in the project, need to be fast tracked or take up too much space on the network diagram are not the primary factors for developing standard subnetworks.

Question 6

A network diagram is a tool for arranging the specific activities in the ____ and defining their ____.

Accepted Answer

A network diagram is a visual representation of the sequence and dependencies of activities involved in a project. It helps to understand the critical path of a project and plan the project timeline accordingly. Therefore, the tool is used for arranging the specific activities in the appropriate sequence and defining their dependent relationships. Option (D) appropriately describes these aspects and is hence the best choice.

Question 7

The ____ is a roadmap that displays how all the specific activities fit together to accomplish the project work scope.

Accepted Answer

The network diagram is a visual representation that shows the sequence of activities and their interdependencies, illustrating how they fit together to accomplish the project work scope.

Question 8

To draw a ____, start by drawing the activities in boxes in their logical sequence and connecting them with arrows to show the required dependent relationships, as the project should be performed from start to completion.

Accepted Answer

The network diagram is a tool used for project scheduling and management. It is a graphical representation of the project activities shown in boxes connected with arrows to show the dependencies between them. It helps to identify the critical path, which is the sequence of activities that cannot be delayed without delaying the overall project completion time. Therefore, the network diagram is the best choice for drawing a project plan or workflow. The work breakdown structure is a hierarchical decomposition of the project into manageable components, the responsibility assignment matrix is a tool used for defining and assigning roles and responsibilities, and the acceptance criteria chart is a tool used for defining the conditions that must be met for the project to be accepted. While these tools are essential in project management, they do not provide a visual representation of the project plan like the network diagram.

Question 9

____ contains a small number of higher-level activities rather than a large number of detailed activities.

Accepted Answer

A summary network is designed to represent a simplified version of a project by showing only the major activities or phases, rather than detailing every single task. This makes it easier to understand the project's overall flow without getting bogged down in minutiae.

Question 10

Each activity in a network diagram is represented by a box in the ____, and the ____ of the activity is written within the box.

Accepted Answer

The answer of Each activity in a network diagram is...

Question 11

Activities should ____ the time intervals at which actual project progress will be reviewed and compared to planned progress.

Accepted Answer

Activities should not be longer in estimated duration than the time intervals at which actual project progress will be reviewed and compared to planned progress. This is because longer activities can hide potential issues or delays in the project, making it difficult to detect and address them in a timely manner. By keeping activities shorter in duration, it allows for more frequent progress reviews and helps to ensure that the project stays on track.

Question 12

Arrows linking the activity boxes in a network diagram show the ____ of the dependent relationship.

Accepted Answer

Arrows in a network diagram always show the direction of the dependent relationship, indicating which activity must be completed before the next can begin. Option A is incorrect as it refers to a different concept in project management. Option C is also irrelevant as the arrow only shows direction, not the strength of the relationship. Option D is incorrect as it refers to slack, which is a measure of flexibility in the schedule and not related to the direction of the dependent relationship.

Question 13

In preparing a network diagram, drawing activities in a ____ is not acceptable because it portrays a path of activities that perpetually repeats itself.

Accepted Answer

A loop in a network diagram is not acceptable because it indicates a never-ending cycle of activities, which is not possible in any project.

Question 14

Designating ____ as having primary responsibility can cause confusion and increase the risk that some work will "fall through the cracks," because each may assume that the other is going to do it.

Accepted Answer

When two or more individuals are designated as having primary responsibility, confusion and miscommunication can easily arise. Each individual may assume that the other(s) is taking care of a certain task, resulting in the work being neglected and not completed. Designating clear and specific roles and responsibilities can prevent this issue.

Question 15

The description of an activity in a network diagram usually starts with a ____.

Accepted Answer

The description of an activity in a network diagram usually starts with a verb, which describes the action that needs to be accomplished. For example, "Install software," "Test system," "Write report," etc.

Question 16

____ in a network diagram will allow the project to be completed in the shortest possible time while making the best use of available resources (the experts).

Accepted Answer

Laddering is a technique used in project management where activities are partially overlapped to reduce the project duration, making efficient use of resources without waiting for each task to be fully completed before starting the next one. This approach allows for a shorter project timeline while optimizing resource utilization.

Question 17

A change in responsibility, that is, a different person or organization takes over responsibility for continuing the work, it should define

Accepted Answer

A change in responsibility marks the end of one activity and the start of other activities in the network diagram. It does not necessarily affect the predecessor or concurrent activities, nor does it mandate serial completion.

Question 18

Each box for an activity in a network diagram is assigned

Accepted Answer

Each box for an activity in a network diagram is assigned a unique activity number to differentiate it from other activities in the network. This is necessary for identifying and tracking each activity throughout the project.

Question 19

A ____ shows their appropriate sequence and defines the dependent relationships indicating how the activities need to be performed to accomplish the overall project work scope and produce the deliverables.

Accepted Answer

A network diagram shows the sequence of activities and their dependent relationships in a visual format, which is essential for managing the project schedule. A responsibility assignment matrix identifies roles and responsibilities, a work breakdown structure breaks down the project scope into smaller, manageable components, and a project scope document defines the project's objectives, deliverables, and constraints. However, none of these documents specifically show the sequence of activities and their dependencies.

Question 20

Activities in a network diagram have ____, that is, they are linked in a logical sequence to show which activities must be finished before others can start.

Accepted Answer

Activities in a network diagram have a dependent relationship, meaning that the completion of one activity is dependent on the completion of another activity before it can start. This logical sequence of dependent relationships is what allows for effective project planning and scheduling.
