Automotive and Aerospace industry are building complex systems and products from a number of supplied components (SW and HW). These products often have long development lifecycles and have stringent requirements for verification, traceability, and document deliverables. OSEE is being developed to provide an integrated solution for lean engineering across the complete product life-cycle. The application framework has as core functionalities a persistence layer that provides a dynamic data model, advanced version control capabilities, and powerful search capabilities. This talk provides an overview of the OSEE Application Framework. There will be a BOF session in the evening for further discussion on the topic.
