Functional requirements are critical in guiding the design of a solution because they outline what the system should achieve. These requirements provide a clear understanding of the desired capabilities, actions, and outcomes that the system must fulfill to meet user needs and business objectives. When the solution design is based on functional requirements, it ensures that all necessary functions are adequately addressed, thereby enabling the development team to create a product that aligns with user expectations.

When functional requirements dictate the design, it facilitates better communication among stakeholders, developers, and users, ensuring that everyone has a shared understanding of the goals and functionalities. This alignment helps minimize misunderstandings and increases the likelihood of delivering a successful solution that meets the intended goals.

In contrast, stating that functional requirements should not dictate the design of the solution overlooks the central role that these requirements play in driving the development process. A solution designed without properly reflecting functional requirements risks delivering a product that may not fulfill its intended purpose, leading to ineffective solutions and dissatisfied stakeholders. Thus, grounding the solution design in functional requirements is essential for the development of effective and relevant systems.
