Which of the following is NOT considered a desirable quality of a good requirement?

In the context of requirements management, multiple or ambiguous requirements are indeed not desirable. A good requirement should be unique and unambiguous, facilitating clear understanding and implementation.

Being necessary is crucial as it indicates that the requirement is essential for the system's intended purpose. Consistency ensures that requirements do not conflict with each other, which is vital for maintaining integrity throughout the development process. Clarity is also important because it helps all stakeholders understand the requirements without confusion.

In contrast, having multiple or overlapping requirements can lead to misunderstandings, hinder project progress, and complicate validation efforts. Therefore, the presence of multiple requirements detracts from the quality of individual requirements, making it the choice that does not align with the characteristics of good requirements.
