Effective Product Development

The best way to understand the MBSE approach is to begin by understanding the alternative: what modeling partitioners call the document-based approach to engineering (and what nonpractitioners call "the way we have always done things!"). With the document-based approach, engineers manually generate some subset of the following artifacts: concept of operations (ConOps) documents, requirements specifications, requirements traceability and verification matrices, interface definition documents, systems design specifications and speciality engineering analysis such as analyses of reliability, FMEA, etc. Document-based systems engineers produce these artifacts in a form of a disjoint set of text documents, spreadsheet, diagrams, presentations (and configuration-manage them in a disjoint set of repositories). The document-based approach is expensive. More precisely, it's more expensive than it needs to be; you incur a significant percentage of total life cycle cost maintaining t...
