domenekrav

Domenekrav, commonly translated as domain requirements, are the constraints and specifications that arise from the problem domain in which a software system operates. They describe how the business context, processes, terminology, regulations, and policies shape what the system must do and how it must behave. Domenekrav can be functional, such as domain-specific rules that govern transaction flows, or non-functional, such as data quality or regulatory compliance constraints. They are distinguished from generic user requirements by their source in the domain and often drive the modeling of the domain itself.

Sources and elicitation: Domenekrav come from domain experts, business analysts, product owners, and compliance officers. Techniques include interviews, workshops, domain-driven design exercises, and building a domain glossary and rules catalog. Deliverables typically include a domain model, a set of business rules, and specifications that map domain terms to system capabilities.

Relation to design and implementation: Domenekrav inform data models, validations, and user interfaces. They influence the creation of domain models, invariants, and constraints, and may be implemented as business rules in a rule engine or expressed as constraints in the database and application logic. Maintaining traceability from domenekrav to design decisions and test cases is essential for validation and change management.

Challenges and governance: Domenekrav evolve with changes in the business environment and regulation, and can conflict with other requirements or be ambiguous without careful definition. Effective management includes formal rule representation, versioning, governance practices, and ongoing collaboration with domain experts to keep requirements aligned with the real world.
