Why should functional requirements dictate the design of the solution?

Functional requirements serve as the foundation for what a system should do. They outline the specific behaviors, features, and capabilities that the final solution must provide. When functional requirements drive the design of the solution, it ensures that every aspect of the design aligns with user needs and system objectives. This alignment is integral to delivering a product that meets expectations and fulfills its intended purpose.

The design that flows from functional requirements allows for a focused approach, ensuring that the technical implementation is not just a technical exercise but rather a means to satisfy defined user needs. By centering the design process around these requirements, the project is more likely to yield a product that stakeholders will accept and appreciate.

While considerations such as scope creep and the analyst's holistic view of the solution might be important, they do not directly relate to the necessity for functional requirements to direct the design process. It's crucial to prioritize functional requirements to maintain relevance to user expectations and project goals.
