RESUMO

Software industry is currently moving towards automation of business processes and applications increasing architectural complexity and the dynamics of requirements change. This work proposes a novel software development process, called SPAREv that includes all todays critical innovations on four areas: Model-Driven Development (MDD); Systematic Reuse; Development by assembly; and Process frameworks. SPAREv employs for: (1) Safe architectural reuse - intent specifications and a customized domain-specific pattern-based software framework; (2) Project variability - metaprogramming and Software Product- Line Engineering (SPLE); and (3) Adaptability - round-tripping and software automation by adopting MDD. A case study on satellite on-board software considers an architectural pattern or framework where project specificities are added as plug-ins, e.g. different control algorithms. Software dependability in this domain is discussed and a novel concept of Pattern-Based Software Fault Tree Analysis (PB-SFTA) presented. Finally, impact is inferred via reuse metrics, e.g. Return on Investment (ROI), and Cost/Benefit analysis. Trends and perspectives are presented highlighting assets and knowledge management, and a Reuse Maturity Model. In order of relevance, the author considers that the three major contributions of this work are: (1) The SPAREv process; (2) The PB-SFTA approach; and (3) The application of metaprogramming into the space software domain.
