formal specification

Formal specification is a precise and structured way of describing what a software system should do, using clear, mathematical language. It defines the system's requirements, behaviors, and constraints without ambiguity. This helps developers and stakeholders understand exactly how the system should function, reduces misunderstandings, and provides a solid foundation for design, implementation, and verification. Essentially, it's like creating a detailed blueprint or rulebook for the software to ensure everyone has a clear, shared understanding of its expected features and behavior before building it.
