Models, Models Everywhere! A practitioners view on the reality of modeling

Abstract

This paper addresses three of the most common real‐world challenges to modeling. The INCOSE Vision 2035 correctly states that the future of SE is Digital and Model Based. Achieving this requires significant development of the state of the art in Digital Engineering and Modeling. The focus of this paper is, however, the significant gap between the current potential of today's models and the actual practice. As practitioners each with over 20+ years of industrial experience, the authors describe problems that plague current modeling practice. The paper: describes the different types of models and their uses; provides a high‐level generic model development approach; and addresses some of the real‐world challenges that modelers and their managers need to address.
