Models and MBSE

Model: a graphical, mathematical (symbolic), physical, or verbal representation or simplified version of a concept, phenomenon, relationship, structure, system, or an aspect of the real world. www.businessdictionary.com

Model: a physical, mathematical, or otherwise logical representation of a system, entity, phenomenon, or process. DoD5000.59-M 1998

Model-based systems engineering (MBSE) is the formalized application of modeling to support system requirements, design, analysis, verification and validation activities beginning in the conceptual design phase and continuing throughout development and later life cycle phases. INCOSE SE Vision 2020, September, 2007

Much of the confusion in MBSE is the ambiguity in “model”. If everything is a model, everything qualifies as MBSE.
