26 Summary There are existing IT-Tools for all phases of an integrated interdisciplinary Product Development Process (SysML, Simulink/Simscape/Matlab, Modelica, MKS, CAD-M/E, Case) There is no accepted, integrated and interdisciplinary design theory and customers have no experiences with this new approach The integration of the System Model and their artifacts Requirements, Functions, Behavior and Logical Building Blocks with PLM/SysLM is absolutely necessary because of traceability regarding international standards (ISO 26262, EN50128, DO178B) The completeness, usability and acceptance of these new tools and processes is not existing but f.e.sysml is a worldwide Standard (OMG) and we should focus on further development The Integration of Mechanic, Electronic and Software along the Product Lifecycle even without the early phases is real challenging..and very seldom realized in industry The risk with the PLM/SysLM project becomes higher with more objects to administrate. But the real problems of unsuccessful PLM implementation is not the quantity of objects, but. VPE Folie: 27

27 Typical PDM/PLM scenarios - Jump as a tiger land as a carpet runner - No vision no budget, vision but no budget, no vision but budget - No Champion, no leadership - MyPLM = I need my own PDM/PLM Solution - To many own developed or over customized PDP/PLM solutions - Missing milestone plan, missing long term perspective - Redundancy and overlapping with legacy systems (ERP), who is master? - No PDM/PLM awareness on management level ( no father, no mother ) - Wrong people to execute the PDM/PLM project - No balance between central defined and executed functions (f.e. engineering item master, ECM process, multi-disciplinary E-BOM) and flexible regional, product or discipline dependent solutions (f.e. TDM,...) - Customers want 150%, suppliers promise 120% and deliver 68% - No guidance from the Solutions Provider and from Management - IT drives processes and not vice versa... - Detailed analysis of technique (System A 3,34 points, System B 3,29 points,...) - Missing user acceptance VPE Folie: 28
