ECBA v3 Requirements Analysis and Design Definition Practice Test

In the context of requirements analysis, consistency refers to the need for requirements to not conflict with each other. When requirements are consistent, they work together harmoniously to provide a clear and coherent picture of what is needed for the system or project. This is crucial because conflicting requirements can lead to confusion, increased costs, and delays, as stakeholders may have different interpretations or expectations based on the requirements that don't align.

When requirements are consistent, it ensures that all stakeholders have a common understanding and agreement on the objectives and functionalities of the project. This alignment helps to streamline the development process, reducing the chances of issues arising during implementation and testing.

The other options relate to aspects of requirements that are important in their own right but do not directly address the concept of consistency. For example, being straightforward and easily understood contributes to clarity but does not guarantee that the requirements do not conflict. Similarly, requirements being documented in detail is essential for thoroughness but does not inherently ensure consistency. Finally, being measurable and quantifiable aids in assessment and validation but does not address whether the requirements themselves are in agreement with one another.
