Even though recognized as a major challenge in system integration, the recently published AUTOSAR standard lacks aspects of timing and performance. Reasons include mismatch between industry requirements and many -mostly academic- timing analysis approaches. There were discussed key technical and non-technical challenges for defining a comprehensive timing model for AUTOSAR and requirements for possible solutions. Examples from practice and a look into the industrial process of designing-and the way of thinking-shall help structuring the discussions. For the future, we ultimately believe that automotive platform design and planning can be much more systematic, if supported by a suitable global timing view that enables reasoning about timing across company borders. Several technological, cultural, and business-related challenges must be tackled. On the one hand, the industrial standardization bodies extremely welcome academic expertise in defining such a model but require careful consideration of established technological and business processes. On the other hand, industry design practice must also evolve to make designs much more transparent and analyzable, possibly imposing new roles and responsibilities for both OEMs and suppliers. Key to a successful timing model will be that industry and academia openly approach each other within a bounded scope of technical problems, clear goals, and willing to compromise.
