Description

Activity: TO: Andreas Jung/Software Systems Division The main result of the COrDeT-2 study – which ended in December 2012 - was the definition and prototype implementation of an on-board software reference architecture (OSRA) for the development of the on-board software of future software systems. During the preliminary dissemination of the results on the OSRA and after the review of the feedback received from early adopters of the OSRA methodology (in particular the two parallel studies named “On-board software reference architecture consolidation” – OSRAc), it became apparent that dissemination of concepts and results using exclusively the project deliverables of COrDeT-2 was inadequate. Project deliverables are in fact mainly written according to the project logic and to respond to contractual engagements. Furthermore they often resemble or consist of a technical specification and risk not to be easily readable by a person who did not participated to the study, and does not know the complete project context in which the results were obtained. The goal of this study was then to create some dedicated training material for the dissemination of the OSRA results. The training material has the advantage of being developed specifically with pedagogical and training goals. This presentation will recapitulate the major phases of the study: 1) preliminary analysis for the identification of major difficulties and misunderstandings concerning the OSRA; 2) selection of the stakeholders to be addressed by the training material (which includes actors of the OBSW development but also OBSW validation and other actors of the avionics / OBSW development, such as avionics engineers, database engineers, satellite operators, etc…); 3) definition of the training material product tree and realization of the training material. The final product tree for the training material includes two groups of documents: 1) “general training material”, which provides introductory information on the OSRA (methodology, concepts, rationale) and targets all stakeholders; and 2) “stakeholder-specific training material”, which addresses technical aspects of the OSRA in details and targets given stakeholders. In the training material we also highlight why the adoption of the OSRA brings considerable advantages not only to its direct users, but also to other actors of the avionics / OBSW process (e.g., avionics engineers, spacecraft database engineers, satellite operators), by highlighting potential improvements in their respective areas and enabled synergies. Finally, we defined “training paths” for each stakeholder, in order to guide them in exploring the training material according to the tasks of their role and the relationship with OSRA. The whole training material will be managed at SAVOIR level for dissemination in the ESA community.
