Model
- B.
Heuristic
- C.
Algorithm
- D.
Theory
Correct Answer
A. ModelExplanation
A metaphor is a figure of speech that compares two unrelated things, highlighting their similarities. In this context, a metaphor is being referred to as another name for a "model". A model is a representation or a simplified version of something, used to understand or explain it better. Just like a metaphor, a model helps to illustrate and convey a concept or idea by comparing it to something else. Therefore, "model" is the correct answer in this case.Rate this question:

Average cost for fixing defects ___________?
- A.
Increases dramatically with the distance between when the defect is introduced and when it is detected
- B.
Increases linearly with the distance between when the defect is introduced and when it is detected
- C.
is unrelated to the distance between when the defect is introduced and when it is detected
- D.
Decreases with the distance between when the defect is introduced and when it is detected
Correct Answer
A. Increases dramatically with the distance between when the defect is introduced and when it is detectedExplanation
The average cost for fixing defects increases dramatically with the distance between when the defect is introduced and when it is detected. This means that the longer it takes to detect a defect, the more costly it becomes to fix it. This is because defects that are detected early can be addressed more easily and with less impact on the overall system. However, if a defect goes undetected for a long period of time, it can have a ripple effect and cause additional issues and complications, leading to higher costs for fixing it.Rate this question:

Extensive up-front planning
- C.
ad hoc planning
- D.
Basic up-front planning
Correct Answer
A. Incremental project planningExplanation
Incremental project planning is the most suitable approach for business systems software projects because it allows for flexibility and adaptability. This approach involves breaking down the project into smaller, manageable phases or iterations, allowing for continuous feedback and adjustments. It enables the project team to deliver working software at regular intervals, ensuring that the project stays on track and meets evolving requirements. Additionally, incremental project planning helps to manage risks effectively and ensures that resources are allocated efficiently throughout the project lifecycle.Rate this question:

Generally a well run project devotes what percent of its schedule to requirements, architecture and up-front planning?
- A.
20-30
- B.
30-50
- C.
5-10
- D.
50-60
Correct Answer
A. 20-30Explanation
A well-run project typically devotes around 20-30% of its schedule to requirements, architecture, and up-front planning. This is because these initial stages are crucial for setting the project's direction, defining its scope, and establishing a solid foundation. Adequate time spent on requirements gathering, creating an architectural design, and planning helps ensure that the project is well-defined, reduces the risk of scope creep, and increases the chances of success. However, allocating too much time to these activities can delay the project's execution and hinder its progress, which is why a balanced approach is necessary.Rate this question:
