All of the following are reasons for design requirements EXCEPT for which one?

• A. Increase security measures of patient records in system design
• B. Clarity of communication between users and development team
• C. Evaluate the functions of a system during design testing
• D. Reduce the time and costs involved in system development

Answer: (A)

Design requirements specify what the system must do and how it should behave so that everyone involved has a shared understanding of the project scope. They guide development decisions and set the basis for validating that the system meets user needs, performance expectations, and constraints.

The item about increasing security measures of patient records is not a primary reason for establishing design requirements. While security is essential in healthcare, addressing security typically happens through security requirements and controls within the design, not as the main purpose for defining the system’s functions and interactions. The remaining points directly support the purpose of design requirements: they help ensure clear communication between users and the development team, they provide a basis for evaluating system functions during testing, and they help reduce time and costs by preventing ambiguity and scope changes.
