2 Content - Automotive Systems Engineering 1. Why do we need Automotive Systems Engineering? 2. What is Automotive Systems Engineering? 3. Process and product view 4. What does it need to implement Automotive Systems Engineering? -2-

3 Challenges - Automotive Systems Engineering Reducing time to market (e.g. until 2006 Volkswagen plans 67 and Daimler plans 60 new models) Improving quality (increasing number of call-backs) Increasing functionality (vehicle guidance, infotain-ment, reduced fuel consumption, drive-by-wire,...) Reducing costs (highly competitive market) -3-

4 Challenges - Automotive Systems Engineering To stand these challenges an integral approach is necessary Automotive Systems Engineering -4-

5 Content - Automotive Systems Engineering Why do we need Automotive Systems Engineering? What is Automotive Systems Engineering? Process and product view What does it need to implement Automotive Systems Engineering? -5-

6 Definition - Automotive Systems Engineering Systems Engineering is not a waterfall process Discover Requirements Design Build Integrate Test -6-

7 Definition - Automotive Systems Engineering Systems Engineering is not a throw it over the wall process Requirements Design Manufacturing -7-

8 Definition - Automotive Systems Engineering Systems Engineering is fractal process The systems engineering process is applied at levels of greater and greater detail. It is applied to the system, then to the subsystems, then to the components, etc. Similarly for the fractal pattern above, the same algorithm was applied at the large structural level, then at the medium-scale level, then at the fine-detail level, etc. -8-

9 Fractal process - Automotive Systems Engineering Requ.analysis Vehicle architecture Function deployment ECU requirements Validation Verification Integration OEM Requ. analysis System test Suppliers Architecture design Integration test Funct. design Module test Implementation -9-

10 Content - Automotive Systems Engineering Why do we need Automotive Systems Engineering? What is Automotive Systems Engineering? Process and product view What does it need to implement Automotive Systems Engineering? -10-

11 Goals - Automotive Systems Engineering Determination of the global optimum with respect to functionality cost weight volume... Investigate alternative concepts Model the system(s) Different variants or changes of the system can be easily designed and compared to the requirements during the complete development process -11-

12 Process view - Automotive Systems Engineering Systematic and general development and design process, which is supported by the appropriate CAE-tools Defined procedures for the development of the organisation and the process (CMMI, SPICE, EFQM,...) Well established project management Well established configuration management Well established requirements management Well established risk management -12-

13 Process view - Automotive Systems Engineering Systems Engineering and Project Management support and supplement each other Systems Engineering is responsible for Doing the right things Determination what is it for and who is it for?? Evaluation of alternative concepts Creating plans Project Management is responsible for Doing things right Determination of how to build and when to build Build according to plans -13-

14 Requirements management - Automotive Systems Engineering Complete the problem statement before defining the requirements Avoid stating the problem in terms of solutions Involve the customer in the process of defining the problem and the requirements (but not for the solution) Requirements have to be written in a clear, unambiguous manner (use figures to quantify them, do not describe them qualitatively) -14-

15 Requirements management - Automotive Systems Engineering Early in the system design consult and involve all stakeholders about requirements Engineering Purchasing Quality control

16 Product view - Automotive Systems Engineering Systematic transition from functional decomposition to component view Functional decomposition independent from implementation Architecture based approach for all (sub)systems, tailorable to different requirements Use of standard components (well defined interfaces and behaviour) Reuse Modelling, simulation, test (verification and validation) at each level of the development process -16-

17 Content - Automotive Systems Engineering Why do we need Automotive Systems Engineering? What is Automotive Systems Engineering? Process and product view What does it need to implement Automotive Systems Engineering? -17-

18 Implementing Automotive Systems Engineering Development: Creatitivity paired with discipline Freedom for creativity, creative ideas light sleep during a journey in the church during a walk

19 Implementing Automotive Systems Engineering Use of the knowledge and experience of the organisation Improvement is always achieved step-by-step or in versions Management Commitment Appropriate process models (CMMI, EFQM,...) Integration of supplier processes (appropriate interfaces) -19-

20 Implementing Automotive Systems Engineering Systems Engineering has to start at the very top of the design processs, i.e. the whole organisation must be involved System development HW-development SW-development Mechanical engineering Purchasing department (make or buy)

21 Implementing Automotive Systems Engineering -21-

22 Implementing Automotive Systems Engineering Engineering and process tools which support a general model based development (supporting interfaces to suppliers, customers and HW, SW,...) Metrics for process and projects Support by highly qualified consultants who distinguish by Know-how in engineering methods and processes Experience in engineering and processes Teaching and coaching capabilities -22-

23 Related areas - Automotive Systems Engineering Knowledge-Management (best practices, lessons learned) and Knowledge-Management-Systems Innovation management (process, products) Quality management Technology management Appropriate education and training to establish a sustainable Systems Engineering process -23-

24 Summary - Automotive Systems Engineering Systems Engineering is the glue that holds it all together Tool 1 Tool 2 Tool 3 Tool 4 Production Pre-Production Component 1 Component 2 Component 3 Component 4 Prototype(s) Design, Model -24-

25 Summary - Automotive Systems Engineering Systems Engineering is responsible for the big picture. It must ensure that the system satisfies its requirements throughout the entire system life cycle, from birth to death There can be no economy where there is no efficiency Benjamin Disraeli -25-
