In 2005, the European Space Agency carried out a study intended to clarify the use of PDAs for onboard space operations. Being this a rather new application domain due to the introduction of uncommon technology onboard, a need for feasibility clarification was perceived. The study narrowed its unbounded technological dimension by focusing on Java technologies. Furthermore, at a software engineering level an "agile" approach was chosen for evaluation because of the high degree of user interaction and their ability to cope with general requirement changes like those resulting from the uncertainty about the actual features and quality of specific PDA platforms and COTS. Two studies were performed in parallel with the same objectives but obtaining different solutions. Suitable "agile-like" approaches compatible with space software standards were defined and tried. A space crew representative was involved from the early phases of the studies, and a final evaluation exercise at the European Astronaut Centre training facilities was performed. Feedback on the suitability of the technologies and the MMI design choices were obtained together with other unexpected lessons. The paper is concluded with an enumeration of lessons learnt and hypotheses about "agile" approaches of interest for the software engineering community.

Although traceability information is vital to many software engineering activities, agile development approaches rarely use it because of the extra effort required. In this industry case study, the authors report the results of applying their lightweight semiautomated method that integrates traceability into software architecture developed with an agile process like Scrum.
