Software reuse has been the subject of empirical studies for decades. There have been studies of reuse methods, success factors, approaches and tools. An open question is still whether and how reuse differs between embedded and nonembedded systems, an important issue for the aerospace industry. This article describes the results from a survey taken at a major aerospace corporation, in order to characterize developers' views on software reuse. 78 developers participated in the survey. The questions focused on modern reuse strategies (whether they were used alone or in combination) and their effectiveness.

This paper discusses a different approach to managing risk in a man-rated software system. This approach emphasizes identifying and targeting the right risks in order to apply effective mitigation activities. It addresses the risk of not understanding the customer wishes, of unreliable software product, and selection of inappropriate reuse. When the right risks are identified with sufficient granularity, resources can be focused on mitigating only those risks. Resources are not spent mitigating general risks or non-risks. The cost can be more correctly estimated and overruns controlled.
