Modellstyrt

Modellstyrt is a Swedish term that translates to "model-driven" or "model-based" in English. It refers to a development or design approach where a central model serves as the primary source of information and drives the creation of other artifacts. This model can take various forms, such as a graphical model, a textual specification, or a combination of both.

In practice, modellstyrt development emphasizes the use of formal or semi-formal models to define the system's structure, behavior, and requirements. These models are then used to generate code, documentation, test cases, or other components of the final product. The core idea is to ensure consistency and reduce errors by having a single, authoritative source of truth.

This approach is commonly employed in software engineering, where model-driven architecture (MDA) and model-driven engineering (MDE) are prominent examples. It is also applicable in other fields like systems engineering, business process modeling, and product design. The benefits often cited include improved maintainability, increased productivity, and better communication among stakeholders, as the models provide a clear and unambiguous representation of the system. However, it also requires expertise in modeling languages and tools, and the initial setup can be more complex than traditional methods.
