MBSE & MDA

Objectives

1. Identify two or three definitive sources for a definition of MBSE(so as not to reinvent the wheel), but context for 3;

2. Identify two or three definitive sources for a definition of MDA (ditto);

3. Form a coherent explanation (graphical and textual) for the relationship(s) of MBSE and MDA;

4. Provide one or more Use Cases or scenarios in which MDA can support one or more SE activities in an MBSE context, and provide illustrations of same.

1 Definitive sources for a definition of MBSE

INCOSE Systems Engineering Vision 2020, INCOSE-TP-2004-004-02, September, 2007:

"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. "

Note the above definition is also cited by "A practical Guide to SysML The Systems Modelling Language", Friendenthal, Moore and Steiner, MK / OMG, second edition, 2012.

Final Report, Model-Based Engineering Subcommittee, NDIA, Feb. 2011:

"Model-Based Engineering (MBE): An approach to engineering that uses models as an integral part of the technical baseline that includes the requirements, analysis, design, implementation, and verification of a capability, system, and/or product throughout the acquisition life cycle."

(This definition located in Slide 8 of file Model-based-Systems-Engineering-MBSE-101.ppt, Model-based Systems Engineering (MBSE) 101, presented at INCOSE International Workshop, 25-26/1/2014, Torrance, CA, USA.)

Wikipedia Entry:

Model-based systems engineering (MBSE) is a systems engineering methodology that focuses on creating and exploiting domain models as the primary means of information exchange between engineers, rather than on document-based information exchange.
