Challenges of Automotive Systems Engineering for Industry and Academia Hermann Winner
1.1 Preface After many years working on systems development in industry and academia, I have developed a personal view of the subject which is reflected in the present paper. This is not based on systematic research, has no claim to be representative and may be highly subjective. It is the product of my experience in a number of predevelopment projects and an initial development for volume production at a tier-one supplier, as well as university research into functional and methodological aspects of Systems Engineering.
1.2 Definition of Terms 1.2.1 System A group of elements which are relevant (and not merely useful) for achieving a purpose, which interact with each other, and which have a structure within predefined boundaries.1 While this and similar definitions allow us to characterise a system, in practice it is particularly difficult to define the boundaries of the system. In a transport system, a road vehicle (possibly together with a driver) is an element of the system. 1
As there are many different definitions for the term “system”, major parts of the present definition will unavoidably overlap with one or several of them. No claim to originality is made, therefore, in regard to this or any subsequent definitions used.

For an automotive manufacturer the car is the system, for the unit responsible for a module—whether a vehicle manufacturer or a module supplier (e.g. for the brakes)— the module is the system, where elements of this system can in turn be elements of another system, e.g. the data communication system or a system which functionally serves a different purpose, such as an Adaptive Cruise Control. A well-chosen system boundary contains all the elements which are relevant to the purpose and amenable to influence, with a minimum level of complexity.
1.2.2 System Design Concept, specification, implementation, verification and validation of a technical system for achieving a specific (and mostly functional) objective. Project management can be an integral or complementary element. This definition consciously follows the familiar V-model, which describes development as a phase of project definition descending to the point of implementation and subsequently rising again through a test phase to the highest level. How far project management is part of system design is a matter of opinion. This will, however, be the case where the system design process involves both functional and organisational roles, e.g. if there is strict separation of responsibility for implementation and responsibility for approval.
