Model maturity levels for embedded systems development, or: Working with warnings

The more modelling substitutes programming the more modelling tools should become development environments. Beyond enforcing the syntactic correctness of models tools should support a methodologically guided development in which milestones are indicated and warnings are generated to inform the user about issues that are to be solved to reach these milestones. In this paper we present an approach from the embedded systems domain that is materialized by the implementation of a prototypical model development environment. It indicates model maturity levels that correspond to an underlying development method and shows in the model maturity view which elements or parts of the model do not yet reach a level and why they do not reach it.
