### How is float calculated?

• A.

Latest finish date – duration

• B.

Latest start date – earliest start date

• C.

Earliest start date + duration

• D.

None of the above

B. Latest start date – earliest start date
Explanation
The correct answer is "Latest start date - earliest start date". This calculation determines the amount of time between the earliest possible start date and the latest possible start date for a task. By subtracting the earliest start date from the latest start date, we can determine the flexibility or float in the schedule. This float represents the amount of time that a task can be delayed without affecting the overall project timeline.

### What does Goldratt’s theory of constraints focus on?

• A.

Pouring resources into minimizing the major constraints facing a project.

• B.

Pouring resources into activities on the critical path.

• C.

Estimating the duration of tasks.

• D.

None of the above

A. Pouring resources into minimizing the major constraints facing a project.
Explanation
Goldratt's theory of constraints focuses on identifying and addressing the major constraints that limit the overall performance of a project. By pouring resources into minimizing these constraints, the theory aims to optimize the project's efficiency and effectiveness. This approach helps to ensure that the project's critical path is not hindered by bottlenecks or limitations, ultimately leading to improved project outcomes.

### What are the limitations of using software to help plan projects?

• A.

It might add to the confusion of the project team and waste time, particularly in multi-national teams.

• B.

Improves visibility of planning among the project team.

• C.

More difficult to use when there are large numbers of tasks and resources.

• D.

None of the above

A. It might add to the confusion of the project team and waste time, particularly in multi-national teams.
Explanation
Using software to help plan projects can have limitations, such as adding to the confusion of the project team and wasting time, especially in multi-national teams. This is because different team members may have varying levels of familiarity and comfort with the software, leading to miscommunication and inefficiencies. Additionally, the complexity of managing large numbers of tasks and resources can make it more difficult to effectively use the software for planning purposes.

### Which of the following is the preferred way of ‘chunking’ a project to create a work breakdown structure?

• A.

Activity breakdown.

• B.

Functional breakdown.

• C.

Physical breakdown.

• D.

All of the above are acceptable ways of chunking any project.

• E.

None of the above are acceptable breakdowns in every case; the best way will depend on the project.

E. None of the above are acceptable breakdowns in every case; the best way will depend on the project.
Explanation
The correct answer states that none of the given options are acceptable breakdowns in every case, and the best way to chunk a project and create a work breakdown structure will depend on the specific project. This means that there is no one-size-fits-all approach to project chunking, and the preferred method will vary based on the unique requirements and characteristics of each project.

### In which sort of project is the use of a Gantt chart most appropriate?

• A.

Projects in which the use of resources must be carefully monitored.

• B.

Projects with few activities and resources involved.

• C.

Projects where the time periods involved are very short.

• D.

Projects with many activities involved.

B. Projects with few activities and resources involved.
Explanation
A Gantt chart is a visual representation of a project schedule, displaying the start and end dates of tasks and their dependencies. It is most appropriate for projects with few activities and resources involved because it allows for a clear and simple overview of the project timeline. With fewer activities and resources, the chart can be easily understood and managed, making it an effective tool for monitoring and tracking progress. However, for projects with many activities or complex resource allocation, a more detailed project management tool may be needed.

### In a network diagram, if the activity in question has several preceding activities on which it is dependent, which earliest start time should be used for the activity in question?

• A.

The earliest of the earliest start times applicable should be used.

• B.

The latest of the earliest start times applicable should be used.

• C.

The mean of all of the possible earliest start times applicable should be used.

• D.

None of the above

B. The latest of the earliest start times applicable should be used.
Explanation
When an activity in a network diagram has several preceding activities on which it is dependent, the earliest start time for each of these activities is calculated. The earliest start time for the activity in question should be determined by considering the latest of these earliest start times. This ensures that the activity can start as soon as all the preceding activities are completed, allowing for maximum efficiency in the project schedule.

### Only delays in tasks on the critical path can delay a project as a whole.

• A.

True

• B.

False

B. False
Explanation
Delays in tasks on the critical path can certainly have a significant impact on the project timeline, but they are not the only factor that can delay a project as a whole. Other factors such as resource constraints, unexpected events, dependencies between non-critical tasks, and poor project management can also contribute to project delays. Therefore, it is not accurate to say that only delays in tasks on the critical path can delay a project as a whole.

### Which explanation best describes what the term ‘crashing’ a project means?

• A.

Abandoning a project when using a stage-gate approach.

• B.

Injecting further funds into a project.

• C.

Reducing the time spans on critical activities to complete the project in less time.

• D.

Failure of a project due to the incompetence of the project manager.

C. Reducing the time spans on critical activities to complete the project in less time.
Explanation
Crashing a project refers to the practice of reducing the time spans on critical activities in order to complete the project in less time. This involves allocating additional resources or increasing the intensity of work to expedite the completion of the project. It is a technique used to compress the project schedule and meet tight deadlines.

### What is a critical path?

• A.

The longest path on a network diagram.

• B.

The shortest path on a network diagram.

• C.

The path that represents the shortest time in which a project could be finished.

• D.

None of the above

A. The longest path on a network diagram.
C. The path that represents the shortest time in which a project could be finished.
Explanation
A critical path is the longest path on a network diagram and represents the shortest time in which a project could be finished. It is the sequence of activities that must be completed on time in order to ensure that the project is completed within the specified timeframe. The critical path helps to identify the activities that have the least amount of flexibility in terms of scheduling and are crucial for the successful completion of the project.

### What is designated as a node in PERT?

• A.

Network

• B.

Event

• C.

Activity

• D.

Dummy Activity

B. Event
Explanation
In PERT (Program Evaluation and Review Technique), a node is designated as an event. In PERT, events represent significant points or milestones in a project, such as the start or completion of an activity. Nodes, or events, are used to depict the sequence of activities and the logical relationships between them in a PERT network diagram. Therefore, the correct answer is Event.
