Perusvaiheessa

Perusvaiheessa is a Finnish term used to describe activities that take place during the basic or initial phase of a project, program plan, or study. The expression emphasizes foundation-setting work that establishes the baseline for later steps.

The word combines perus- meaning basic and vaihe meaning phase, with the inessive suffix -ssa, yielding "in the basic phase." It is used in written and spoken Finnish to situate statements temporally and procedurally.

In education, perusvaiheessa can refer to early stages of curriculum development or program evaluation. In project management and product development, it marks the scoping, requirements gathering, risk assessment, and baseline measurement tasks. In research, it denotes the design and data-collection phase preceding analysis.

Typical characteristics include establishing aims, identifying stakeholders, mapping resources, and defining indicators and success criteria. Decisions made in this phase influence subsequent development, implementation, and evaluation.

Because Finnish terminology varies by field, the exact scope of the perusvaiheessa period is not standardized; it may be defined differently in guidelines, manuals, or institutional contexts.
