Esikokeilu

Esikokeilu is a term used in Finnish research, development, and public sector contexts to describe a small-scale preliminary trial conducted before a full-scale project or program. The aim is to test whether the planned methods, procedures, and logistics are workable and to identify potential problems early. Esikokeilu can apply to research studies, software or product development, educational interventions, and public services.

The purpose of an esikokeilu is to assess feasibility and practicality rather than to test definitive hypotheses. It typically focuses on process and implementation questions: can recruitment be achieved as planned? Are data collection tools usable and reliable? Are procedures and timelines realistic? It may also gather initial feedback on acceptability and user experience. Design features often include a limited sample, shorter duration, and a scope that mirrors essential elements of the intended larger project without aiming for statistical power.

Esikokeilu is closely related to feasibility and pilot studies. In some contexts the terms are used interchangeably, while in others esikokeilu emphasizes operational feasibility and workflow testing. It should include planning, execution, and evaluation steps, with a clear decision point about whether to proceed to a full-scale implementation, modify the plan, or discontinue.

Reporting an esikokeilu typically covers objectives, methods, participants, feasibility outcomes (such as recruitment rates, adherence, timing, costs), and lessons learned. Transparent documentation helps stakeholders decide on next steps and informs the design of subsequent, larger studies or deployments.
