Systems Engineering – A (long) definition

Source: INCOSE Website – What is Systems Engineering?

Systems Engineering is an interdisciplinary approach and means to enable the

realization of successful systems. It focuses on defining customer needs and required

functionality early in the development cycle, documenting requirements, then

proceeding with design synthesis and system validation while considering the complete

problem:

� Operations

� Cost & Schedule

� Performance

� Training & Support

� Test

� Disposal

� Manufacturing

Systems Engineering integrates all the disciplines and specialty groups into a team effort

forming a structured development process that proceeds from concept to production to

operation. Systems Engineering considers both the business and the technical needs of

all customers with the goal of providing a quality product that meets the user needs.

Systems Engineering – Another definition

Systems Engineeringfocuses on ensuring

the pieces work together

to achieve the

objectives of the whole.

The worries of today’s projects

The global market demands

ever more complex systems

while shorter time-to-market times, high quality, and decreasing costs.

Are our current development techniques suitable for these challenges?

Is this an appropriate

approach for

systems?!

Working with models

…or is this rather the way how engineers

think about complex systems?

Model-based Systems Engineering

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.

OMG Systems Modeling Language

SysML is designed to provide simple but

powerful constructs for modeling a wide range

of systems engineering problems. It is

particularly effective in specifying

requirements, structure, behavior, allocations,

and constraints on system properties to

support engineering analysis.

Source: OMG SysML™ 1.3 specification

Short history of SysML

� January 2001: INCOSE establishes a working group to adapt the UML for Systems Engineering

� July 2001: INCOSE & OMG jointly chartered the OMG SE DSIG

� In the following years there have been some disagreements and competing ideas …

� … but in 2006 a SysML specification proposal was adopted by the OMG.

� September 2007: SysML 1.0 was officially released byOMG

� Since June 2012: Version 1.3

� Version 1.4 is ready and will be published soon

Delimitation between UML and SysML

� New diagrams, e.g.: block definition diagram, requirements diagram, …

� New elements, e.g.: requirement, allocation, support for continuous systems

� New notations

� SysML excludes some UML model elements explicitly, e.g. components

� Mission: Testing of new technologies and scientific

Earth observation

� Developed and built by

students and PhD candidates

� Weight: approx. 120 kg

� Dimensions: 60 x 70 x 85 cm

� Planned start: 2015, expected lifespan: 2 years

INCOSE Vision 2025

Formal systems modeling is standard practicefor specifying, analyzing, designing, and

verifying systems, and is fully integrated with

other engineering models. System models are

adapted to the application domain, and

include a broad spectrum of models for

representing all aspects of systems.

Conclusion

� Systems Engineering as an interdisciplinary

approach to develop complex products will

strongly gain in importance

� The document-based approaches from the

industrial age are no longer suitable in the

era of ever-increasing complexity

� MBSE is a key success factor of modern
