Language is a structured system of signs that people or systems use to express and communicate information.
These signs may include words, symbols, sounds, gestures, or formal expressions. Therefore, the chosen form affects how clearly stakeholders understand requirements.
Natural language supports communication with most stakeholders. However, it can create ambiguity and inconsistent interpretations. Short sentences, consistent terms, and structured templates reduce these risks.
Modeling languages use defined symbols and rules. For example, UML, BPMN, and SysML describe structures, processes, and system behaviour. Moreover, formal languages use mathematical notation to provide greater precision.
Teams may combine several forms. For example, they can document goals in plain text and represent processes with diagrams. In addition, they may use formal expressions for critical rules.
Selecting the right language improves clarity, consistency, verification, and stakeholder communication.
