requirir

Requirir is a fictional framework for requirements engineering and project governance used in educational and speculative design contexts. It is described as a method for modeling, validating, and tracing requirements across product lifecycles, integrating elicitation, verification, and impact analysis.

Origin and development: The concept was created in the 2010s by a collaboration of academic and professional writers to illustrate structured requirements management. It has appeared in course materials, scenario analyses, and mock projects rather than in actual industry deployments.

Core concepts: Requirir represents requirements as nodes in a directed graph connected by dependencies, derivations, and constraints. Each node may reference related design artifacts, tests, risk items, and obligations. The framework supports baselines, versioning, and automatic change propagation to dependent items.

Variants and tooling: In its fictional ecosystem, Requirir includes Requirir Core (the modeling language), Requirir Studio (visual editor), and Requirir Lab (simulation and analysis environment). Emphasis is placed on traceability, justification, and scenario-based reasoning.

Reception and usage: In educational contexts, Requirir is praised for clarifying relationships among requirements and for teaching traceability practices. Critics argue that its formalism can be overly complex for small projects and that it remains a speculative construct rather than a widely adopted industry standard.
