On Applying FMEA to SOAs: A Proposal and Open Challenges

Service Oriented Architectures (SOAs) are being increasingly used to support business-critical systems, raising natural concerns regarding dependability and security attributes. In critical applications, Verification and Validation (V&V) practices are used during system development to achieve the desired level of quality. However, most V&V techniques suit a structured and documented development lifecycle, and assume that the system does not evolve after deployment, contrarily to what happens with SOA. Runtime V&V practices represent one possible solution for this problem, but they are not possible to implement without the adjustment of traditional V&V techniques.
