Question 1

The amount of time that an activity can be delayed without delaying the project refers to:

Accepted Answer

Slack time, also known as float time, refers to the amount of time that an activity can be delayed without delaying the overall project. It is calculated by subtracting the early start time of an activity from the late start time, or by subtracting the early finish time from the late finish time. Noncritical time and down time are not commonly used terms in project management. Delay time could refer to any amount of time that an activity or the project as a whole is delayed, and does not specifically refer to the amount of time that an activity can be delayed without impacting the project.

Question 2

What would be the estimated time for completion if time estimates for programming are as follows: optimistic = 4 weeks;pessimistic = 6 weeks;realistic = 5 weeks?

Accepted Answer

The best estimate for completion time in this situation is the realistic estimate, which is 5 weeks. The optimistic and pessimistic estimates are used to calculate a range of possible outcomes, but the realistic estimate is considered the most accurate. Therefore, the estimated time for completion would be 5 weeks.

Question 3

In OOSAD,one outcome of defining the overall system as a collection of components is:

Accepted Answer

Defining the overall system as a collection of components can lead to greater redesign and rework for components that were constructed earlier in the project, as changes to these components may have cascading effects on the rest of the system.

Question 4

Realistic time is:

Accepted Answer

Realistic time refers to the planner's "best guess" of the amount of time an activity will take to be completed based on factors such as resource availability, constraints, and past experience. It is neither the maximum nor minimum time, and not necessarily the actual time it will take, but a realistic estimation.

Question 5

What would be the estimated time for completion if time estimates for installation are as follows: optimistic = 1 week;pessimistic = 1 week;realistic = 1 week?

Accepted Answer

Since all time estimates (optimistic, pessimistic, and realistic) are the same, the estimated time for completion is 1 week.

Question 6

In OOSAD,each project iteration has all of the following except:

Accepted Answer

Every project iteration in OOSAD typically involves planning, analysis, and implementation phases. However, the project closedown phase is not a part of each iteration. It's typically carried out only at the end of the entire project or when a major milestone has been achieved.

Question 7

When a project manager divides a system into components in OOSAD,each component is called a(n):

Accepted Answer

Dividing a system into components in OOSAD is commonly referred to as vertical slicing. This involves breaking down the system into individual components that are self-contained and can be developed, tested and maintained independently. Horizontal slicing refers to dividing the system by layers or tiers, while "piece of the pie" and "node" are not commonly used terms in OOSAD.

Question 8

Slack time is equal to:

Accepted Answer

Slack time is the amount of time an activity can be delayed without causing a delay to the overall project schedule. It is calculated as the difference between an activity's latest and earliest expected completion time. Therefore, choice A is the correct answer.

Question 9

Which of the following is a true statement regarding network diagrams?

Accepted Answer

All three statements are true regarding network diagrams. The critical path is the longest sequence of connected activities that determines the overall time to complete the project. Activities with zero slack time are on the critical path, and any delay in these activities will delay the project's overall completion. Activities that are not on the critical path can be delayed without delaying the final completion of the project.

Question 10

In OOSAD,iterations are normally:

Accepted Answer

In OOSAD, iterations are typically shorter than in traditional software development methodologies and can range from two to eight weeks. This shorter time frame allows for more frequent feedback and adjustments to be made throughout the development process, leading to a more flexible and responsive approach to software development.

Question 11

What would be the estimated time for completion if the time estimates for report design are as follows: optimistic = 3 weeks;pessimistic = 9 weeks;realistic = 6 weeks?

Accepted Answer

The best estimate for completion time is realistic estimate of 6 weeks. The optimistic and pessimistic estimates provide a range of possible durations, but the realistic estimate reflects the most likely duration to complete the report design. Therefore, the best choice is B, 6 weeks.

Question 12

A critical path is:

Accepted Answer

A critical path is a sequence of activities whose order and durations directly affect the completion date of a project. In other words, any delay in activities on the critical path will directly delay the completion of the project.

Question 13

Optimistic time is:

Accepted Answer

Optimistic time is the minimum period of time required to complete an activity, assuming everything proceeds better than expected.

Question 14

Pessimistic time is:

Accepted Answer

Pessimistic time refers to the longest time period an activity might take to complete, considering potential delays and worst-case scenarios.

Question 15

Which of the following is true regarding Gantt chart construction?

Accepted Answer

Gantt chart construction involves drawing a horizontal bar for each activity that reflects its sequence and duration. Arrows may be used to show relationships between activities, but they are not necessary for the basic construction of the chart. Squares are not typically used to represent activities in a Gantt chart.

Question 16

Automated tools available to help you manage a development project are referred to as:

Accepted Answer

Automated tools designed to help manage development projects are called project management software. Options A, C, and D are not appropriate as they do not accurately describe the purpose of these tools.

Question 17

A ________ is a systems analyst with a diverse set of skills-management,leadership,technical,conflict management,and customer relationship-who is responsible for initiating,planning,executing,and closing down a project.

Accepted Answer

The answer of A ________ is a systems analyst with...

Question 18

In OOSAD,the project manager must:

Accepted Answer

The project manager in OOSAD, or Object-Oriented System Analysis and Design, must subdivide the whole system into a set of components. This is necessary so that each component can be designed and developed separately, and then integrated into the overall system. Using Java to design the system may be a choice, but it is not a requirement. Keeping track of objects is also necessary, but it is just one part of the overall process of OOSAD. Therefore, the best choice is A, as it directly addresses the main task of the project manager in this process.

Question 19

A characteristic of the OOSAD approach is:

Accepted Answer

The OOSAD approach, which stands for Object-Oriented Systems Analysis and Design, aims to tackle hard problems first by breaking them down into smaller, manageable parts. This approach emphasizes the importance of understanding the problem before designing a solution, and it uses object-oriented concepts to model real-world scenarios. Therefore, Option D is the correct choice as it emphasizes the characteristic of tackling hard problems first.

Question 20

A ________ is a planned undertaking of related activities to reach an objective that has a beginning and an end.

Accepted Answer

The answer of A ________ is a planned undertaking of...
