Systems Engineering’s Objective

Translate user operational needs into an efficient and cost-effective system solution

Capture the solution in a complete and coherent* system documentation** needed to design, integrate, test, operate and logistically support a system that fully meets user operational needs

– Specification

– Design

– Test

– Operation

– Support

– Other Supporting Work Products: Trade Studies, Analyses, Technical Reports, Meeting Minutes…

* Coherent: Composed of mutually dependent parts; making a logical whole; consistent; as a coherent plan, argument, or discourse. Webster Dictionary** Also known as work products

Systems Engineering’s Challenge

System requirements, design data, and information relevant to a wide variety of engineering, technical and domain disciplines

– Totality of requirements in the thousands (possibly tens of thousands); Often changing, sometimes well into design

– Dozens (possibly hundreds) of scientists, specialists, engineers, designers, testers, manufacturers…, from multiple & diverse technical disciplines

– Customers, operators, maintainers, suppliers… with great domain expertise, little engineering expertise (and vice versa)

– Should tie together into a unified whole

– Should always be traceable to User Operational Needs

Hundreds to thousands of components employing a wide variety of technologies manufactured throughout the country, possibly the world (ex. International Space Station)

Never ending issues and risks associated at varying development levels that span a wide range of technical and domain expertise

Essential Elements of a MBSE Method

1. Use of models as the central and unifying element to the development of a system*

2. Application across SE processes

3. Application down and up development levels

4. Application throughout system lifecycle

5. Use of computerized SE tools to support the method

* “…model-based [systems] engineering is about elevating models in the engineering process to a central and governing role in the specification, design, integration, validation, and operation of a system.” Estefan, J.A., Survey of Model Based Systems Engineering Methodologies, INCOSE MBSE Focus Group (http://syseng.omg.org/MBSE_Methodology_Survey_RevA.pdf)

9

1. Models as Central and Unifying Element

Well defined, unambiguous language/notation, understood by all stakeholders, to describe and analyze the system

Multiple system views to fully communicate system requirements and design

– Requirements, Behavioral, Structure, Performance, Data, Managerial…

– Integrated/Traceable; Complimentary; Consistent…non contradictory

Underlying structure (or schema) to define model elements, attributes and relationships – Information Model

Executability

Models are the primary means of communication with clients, builders, and users; models are the language of the architect. The Art of Systems Architecting, Maier, M., Rechtin, E., CRC Press, 2002

5. Use of Computerized SE Tools to Support the MBSE Method

Modeling

– Support the modeling language and schema; produce the needed system views

– Maintain horizontal and vertical traceability

Data Management

– Single, central repository to manage all related system data and information

Document Generation

– Automated generation of formal documentation & work products (drawn from central model repository)

System/Segment Specification (SSS); Interface Requirements Specification (IRS); Test & Evaluation Plan (TEP); Software Requirements Specification (SRS)...

Integral to the SE Environment to support the MBSE method

See Survey of Model Based Systems Engineering Methodologies (http://syseng.omg.org/MBSE_Methodology_Survey_RevA.pdf) for a discussion of commercial tools available that could be used to support MBSE method application

Conclusion

Application of a Model Based Systems Engineering methodology can contribute to the implementation of an effective Risk Management program because:

– Models can effectively communicate system requirements and design detail to all disciplines, at all system levels; Simultaneously accessible to all team members (IPTs, special study groups, analysis teams, etc.) (identification)

Executable models allow analysis of system behavior (assessment and analysis)

– Risk documentation products - identified risks, assessment results, mitigation plans etc. – can become an integral part of the system models, maintained in central repository (management)

– Risk documentation products can be automatically generated from tools supporting SE environment drawing model data from central repository (management)

MBSE methodology allows Risk Management to become an integral part of the overall system development effort, throughout all development phases/levels, throughout the system lifecycle (management)

Model Driven Engineering (MDE)

Model Driven Architecture (MDA)1,2

Model Driven Development (MDD)1,2

Model Based Application Development1

Model Based Programming1

Object Oriented Systems Engineering Method (OOSEM) using SySML1

Rational Unified Process for Systems Engineering (RUP SE)3

1. Object Management Group (OMG) trademarks (http://www.omg.org/legal/tm_list.htm)

2. MDA & MDD are actually implementations of MDE

3. IBM Rational trademark

How do these differ from MBSE?or MBE or MDSD
