Natural Language Specifications
Natural Language Specifications (NLS) is a software development methodology that uses human-readable, plain language descriptions to define system requirements, behaviors, and tests. It bridges the gap between technical and non-technical stakeholders by expressing specifications in a format that is understandable to all parties, often serving as executable documentation that can be automatically validated. This approach enhances clarity, reduces misunderstandings, and supports behavior-driven development (BDD) and test-driven development (TDD) practices.
Developers should learn and use Natural Language Specifications when working on projects that require close collaboration with business analysts, product managers, or clients to ensure requirements are accurately captured and implemented. It is particularly valuable in agile environments for defining user stories, acceptance criteria, and automated tests, as it helps prevent scope creep and improves software quality by making specifications testable and verifiable. Use cases include developing complex business applications, regulatory compliance systems, or any project where clear communication of requirements is critical to success.
