perusmääritys

Perusmääritys is a Finnish term used in technical and scientific contexts to denote the act or result of establishing the basic or baseline determination of a system, process, or problem. It involves defining the essential properties, parameters, criteria, or reference values that serve as a foundation for further analysis, design, measurement, or decision making. The concept emphasizes what is fundamental and stable against which changes or deviations can be assessed.

Etymology reflects its meaning: perus means basic or foundational, and määritys means determination or specification. The term is mostly found in Finnish-language documentation and literature in engineering, quality management, measurement science, and related fields. Because it is not a rigid, universally standardized term, its exact scope can vary by discipline and organization.

Usage and scope: Perusmääritys is typically used when a project or study requires a clear statement of core requirements or reference conditions before proceeding to more detailed design, testing, or analysis. It can encompass baseline performance metrics, core specifications, reference standards, and essential criteria that define success for subsequent work. In practice, it helps align stakeholders by providing a shared, stable starting point.
