With an Open Mind: How to Write Good Models

Abstract

Writing effective models for systems and their environment is a challenge. The task involves both mastering the modeling tool and its notation, and faithfully translating all requirements and specifications into a complete model. The former ability can be learned, while the latter one is a continuous challenge requiring experience and tools supporting the visualization and understanding of models. This paper describes our experience with incomplete models, the types of changes that were made later, and the defects that were found with the improved models. © Springer International Publishing Switzerland 2014.
