vaatimusperusta

The term vaatimusperusta is a Finnish phrase that translates literally to “requirement basis.” It is used primarily in technical and regulatory contexts to denote the foundational set of requirements that guide the design, implementation, and evaluation of systems, processes or products. The concept is central to Finnish engineering standards, safety analysis, and quality management systems, where it helps ensure that all necessary functional and non‑functional criteria are identified and documented before a project proceeds to detailed design or procurement.

A vaatimusperusta typically includes explicit functional requirements, performance targets, compliance obligations, and stakeholder expectations. In the context of safety‑critical systems—such as automotive, energy or medical devices—it forms the basis for risk assessment, safety case development and certification. Regulatory agencies in Finland often refer to a completed vaatimusperusta as evidence that a system meets mandatory requirements, and the document may be required during audits or inspections.

The development of a vaatimusperusta follows a disciplined methodology: stakeholders are consulted to elicit requirements; requirements are validated against industry standards; and the set is formalised in a structured specification. Maintaining a clear vaatimusperusta throughout a project lifecycle supports traceability, reduces the likelihood of omissions or conflicts, and facilitates later verification and validation activities.

Although the term originates in Finnish practice, the underlying idea aligns with international concepts such as the “requirements base” or “design baseline” used in Project Management Professional (PMP) and ISO 9001 quality management frameworks. The vaatimusperusta thereby plays a critical role in ensuring that Finnish technologies meet both domestic regulations and global best practices.
