Question 1

Project time includes all the required processes to manage and complete the project in a timely fashion.

Accepted Answer

Project time management is one of the key aspects of project management that includes all the necessary processes required to manage, schedule, and complete the project in a timely fashion. It involves determining the project timeline, sequencing of project activities, estimating activity durations, developing a project schedule, monitoring and controlling the project schedule, and ultimately delivering the project on time. Therefore, the statement is true.

Question 2

PDM uses time as a common factor to analyze other project success factors like scope,resources,cost,performance,and value.

Accepted Answer

PDM (Project Development Methodology) is a project management technique that uses time as a common factor to analyze and coordinate other project success factors such as scope, resources, cost, performance, and value. PDM helps to determine the project timeline, identify critical path activities, manage dependencies, and track progress against planned schedules.

Question 3

One very important purpose of constructing and using PDM is to determine how much time is needed to complete a project.

Accepted Answer

PDM (Project Dependency Management) is a method used to represent the sequence of activities in a project and their dependencies. By using PDM, it is possible to estimate the duration of a project and to determine the critical path, which is the sequence of activities with the longest duration and no slack time. This information is crucial to determine the project schedule and to allocate resources effectively. Therefore, it is true that one very important purpose of constructing and using PDM is to determine how much time is needed to complete a project.

Question 4

An activity on the critical path has several days of free float.

Accepted Answer

If an activity is on the critical path, it means it has no free float. Free float refers to the amount of time an activity can be delayed without affecting the early start date of the following activity. If an activity on the critical path has free float, it means it is not truly on the critical path and could potentially be delayed without affecting the project timeline.

Question 5

PERT is inexpensive to maintain and primarily used for small to medium sized projects.

Accepted Answer

PERT (Program Evaluation and Review Technique) is a project management tool that is primarily used for large and complex projects. While it can be used for small to medium sized projects as well, it is not considered to be an inexpensive tool to maintain.

Question 6

A significant disadvantage of PDM and PERT is that they should not be used in times of uncertainty.

Accepted Answer

PDM (Precedence Diagramming Method) and PERT (Program Evaluation and Review Technique) are often used precisely when there is uncertainty in a project's timeline. They help to identify critical paths, estimate project completion times, and manage risks.

Question 7

Capacity measures how early or late an activity can start or finish.

Accepted Answer

Capacity measures the maximum amount of work that a system or resource can handle, whereas early or late start or finish times are measured in terms of duration, slack, or float.

Question 8

In PDM,an activity can have successors with no predecessors.

Accepted Answer

In PDM (Precedence Diagramming Method), activities can have successors without any predecessors. These activities are called initial activities or starting activities.

Question 9

Before any successor activity can be initiated in PDM,all the activities that precede that activity have to be completed.

Accepted Answer

PDM (Precedence Diagramming Method) is a network diagramming technique used in project management. It uses arrows to show the relationships between different activities in a project. In PDM, each activity has a predecessor and a successor. The successor activity cannot start until the predecessor activity is complete. Therefore, before any successor activity can be initiated in PDM, all the activities that precede that activity have to be completed.

Question 10

In PDM,an activity can have predecessors with no successors.

Accepted Answer

In PDM (Precedence Diagramming Method), an activity can have predecessors with no successors. This is because PDM diagrams show the dependencies between activities, and some activities may have dependencies on activities that are not followed by any other activities in the project. These activities can still be shown on the PDM diagram with no successors.

Question 11

Project Evaluation and Review Technique is a project management tool used to schedule,organize,and coordinate tasks within a project.

Accepted Answer

Project Evaluation and Review Technique (PERT) is used to effectively manage and plan projects by analyzing and sequencing tasks, estimating the time and resources required for each task, identifying critical path and controlling the project schedule. PERT is a widely used project management tool in various industries.

Question 12

In PDM,a project will have one start activity and at least two finish activities.

Accepted Answer

In PDM, a project can have multiple start and finish activities.

Question 13

A work breakdown flowchart is useful for all stakeholders to track the project from beginning to finish.

Accepted Answer

The answer of A work breakdown flowchart is useful for...

Question 14

Causing a delay to the whole project is called free float.

Accepted Answer

Causing a delay to a specific activity without affecting the overall project schedule is called free float.

Question 15

The earliest finish time is the total of the earliest start time and the activity duration.

Accepted Answer

The answer of The earliest finish time is the total...

Question 16

Free float is an early warning and an indicator that corrective measures to scheduling have to be taken.

Accepted Answer

Free float refers to the amount of time that a schedule activity can be delayed without delaying the early start date of any immediately following activities, not necessarily an indicator that corrective measures need to be taken.

Question 17

Primary advantages of PERT are that it is flexible and easy to use.

Accepted Answer

PERT (Program Evaluation and Review Technique) is known for its ability to handle uncertainty in project schedules by using probabilistic time estimates, but it is often considered complex and more difficult to implement compared to simpler project management tools, due to its reliance on statistical methods and the need for detailed analysis.

Question 18

If the early start for an activity is 7 and the late start is 12,then the activity's slack is 84.

Accepted Answer

The slack of an activity is calculated by subtracting the duration of the activity from the difference between the late start and early start times. Therefore, the slack for this activity would be:

Slack = (Late start - Early start) - Duration
Slack = (12 - 7) - Duration
Slack = 5 - Duration

There is not enough information given to calculate the duration of the activity, so we cannot determine the slack. Therefore, the statement is False.

Question 19

SAP PS is a free,web-based project software package.

Accepted Answer

SAP PS (Project System) is a project management module within SAP ERP system, which is not a free software package and requires a license to use.

Question 20

When making a forward pass through a network,the earliest start time of a successor activity is the earliest finish date of a predecessor.

Accepted Answer

This is true according to the concept of forward pass in project management. When performing a forward pass, the earliest start time for each activity is calculated based on the earliest finish time of its predecessor activity.
