Functional Requirements vs Non-Functional Requirements
Developers should learn and use functional requirements to ensure that software is built to meet user expectations and business goals, reducing rework and misalignment meets developers should learn and use non-functional requirements to design robust, scalable, and maintainable software systems, as they directly impact user satisfaction and system success. Here's our take.
Functional Requirements
Developers should learn and use functional requirements to ensure that software is built to meet user expectations and business goals, reducing rework and misalignment
Functional Requirements
Nice PickDevelopers should learn and use functional requirements to ensure that software is built to meet user expectations and business goals, reducing rework and misalignment
Pros
- +They are essential during the requirements analysis and design phases of software development, particularly in projects following methodologies like Waterfall or Agile, where clear specifications help in creating accurate estimates, test cases, and validation criteria
- +Related to: non-functional-requirements, requirements-analysis
Cons
- -Specific tradeoffs depend on your use case
Non-Functional Requirements
Developers should learn and use non-functional requirements to design robust, scalable, and maintainable software systems, as they directly impact user satisfaction and system success
Pros
- +For example, in e-commerce applications, NFRs like response time under 2 seconds and 99
- +Related to: software-architecture, system-design
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use Functional Requirements if: You want they are essential during the requirements analysis and design phases of software development, particularly in projects following methodologies like waterfall or agile, where clear specifications help in creating accurate estimates, test cases, and validation criteria and can live with specific tradeoffs depend on your use case.
Use Non-Functional Requirements if: You prioritize for example, in e-commerce applications, nfrs like response time under 2 seconds and 99 over what Functional Requirements offers.
