Producteisen

Producteisen is the set of conditions and capabilities a product must satisfy to meet the needs of stakeholders. The term is commonly used in Dutch and German-speaking contexts as a shorthand for product requirements or product specifications. Producteisen form the foundation for design, development, testing and validation, and are established through requirements engineering, a cross-disciplinary effort that involves product owners, users, customers, engineers and regulatory bodies. The goal is to articulate what the product should do, how well it should perform, and under what constraints.

Requirements are typically categorized as functional, non-functional, and constraints. Functional requirements describe specific behaviors or features. Non-functional requirements specify quality attributes such as performance, reliability, security, usability and maintainability. Constraints cover regulatory, technical, environmental or interoperability limits, and data or interface specifications.

The lifecycle of producteisen includes elicitation, analysis, specification, validation and ongoing management. Elicitation gathers stakeholder needs through interviews, workshops and observation; analysis resolves conflicts and prioritizes needs. Documentation can take the form of user stories, use cases, a formal requirements specification or a product backlog with clear acceptance criteria. Good requirements are traceable to design elements, tests and business objectives, and are baselined to control changes.

Common challenges include ambiguity, scope creep, changing requirements, and ensuring stakeholder alignment. In practice, requirements are often maintained in agile backlogs or requirements documents, evolving through iterative refinement and continuous verification. Standards such as ISO/IEC/IEEE 29148 and IEEE 830 provide guidance for documenting and managing producteisen, though many organizations adapt these practices to their context.
