järjestelmämockupti

Järjestelmämockupti is a neologism formed from the Finnish words järjestelmä (system) and mockup, used to describe a system-level mockup or integrated prototype that represents the structure, interfaces and typical flows of a software or socio-technical system. The term is not tied to a single methodology but commonly denotes artifacts that go beyond single-screen designs to illustrate component interactions, data flows, and stakeholder touchpoints.

Typical järjestelmämockupti artifacts vary in fidelity from schematic diagrams and annotated wireframes to interactive prototypes that simulate messages, API calls and multi-user scenarios. They are used in requirements elicitation, usability testing, architectural review and stakeholder alignment to make systemic behavior visible early in development.

Benefits attributed to järjestelmämockupti include earlier detection of design flaws, improved cross-disciplinary communication, and reduced risk when planning integrations or deployments. They support iterative development by allowing teams to validate assumptions about dependencies, error handling and user journeys without implementing full functionality.

Limitations include the risk of overconfidence in simulated behavior—performance, security and scale often cannot be fully assessed in a mockup—and the effort required to keep the mockup synchronized with evolving requirements. Best practices recommend clear scope definition, explicit fidelity levels, and combination with other artifacts such as sequence diagrams, test plans and pilot deployments.

Usage of the term is primarily regional and informal; equivalent concepts are commonly discussed internationally under system mockup, integrated prototype or end-to-end prototype.
