ABSTRACT
A good model is a good guide for process execution. Model-Based Engineering is a general 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 a systems life cycle. A model facilitates repeatability and consistency of activities in a systems environment. In general terms, a model is a simplified version of a concept, phenomenon, relationship, structure, organization, enterprise, or system. Model-Based Systems Engineering (MBSE) provides a means for driving more systems engineering depth without increasing costs. Data-centric specifications within MBSE enable automation and optimization, and unity of focus on value-added tasks. Model-Based Systems call for incorporating models into the overall operational scheme of the organization. In statistical modeling of manufacturing processes, sigma refers to the number of defects per given number of items created.
