mallitason

Mallitaso, commonly referred to in its genitive form mallitason in Finnish, is a term used to describe the level of abstraction or detail chosen for a model of a system, process, or dataset. It signals how much of the real world is represented and what aspects are prioritized for analysis, communication, or decision making.

The concept is widely used across domains such as information technology, systems engineering, business process modeling, data modeling, and simulation. In practice, analysts and designers select a mallitaso to balance clarity and usefulness against complexity and cost. A high mallitaso (conceptual) focuses on goals, actors, and major flows, while a low mallitaso (physical or implementation level) includes concrete structures, schemas, interfaces, or code-level details.

Common modeling layers include conceptual, logical, and physical representations. Moving from a higher to a lower mallitaso typically increases specificity and precision but also raises maintenance needs and the risk of mismatch with evolving requirements. Effective use of mallitaso involves aligning stakeholders, ensuring traceability between levels, and clearly documenting assumptions and scope.

Relation to broader terms includes abstraction level and level of detail (LOD) in modeling and design. While not governed by a single international standard, the concept remains a practical guide for organizing information, communicating architecture, and planning implementations.
