Pattern Catalog for Capability Diagnostics and Improvement of Service-oriented Enterprise Architectures

摘要

An original pattern catalog for capability diagnostics and optimization for change of service-oriented enterprise architectures is introduced. The current approaches for assessing maturity of software architectures were intuitively developed, having sparse meta model foundation and being rarely validated. This is a real problem because enterprise and software architects should know what is a successful path for introducing and changing service-oriented enterprise architectures. Our contribution is to extend existing Service Oriented Architecture (SOA) maturity models to accord with a sound meta model approach based on the well understood and standardized Capability Maturity Model Integration (CMMI), which was originally used to assess software processes and not architectures. Our specific architecture capability evaluation approach is the result of a meta model-based synthesis and conception and was grounded on the current Open Group Architecture Framework (TOGAF) standard for enterprise architectures. Applying the maturity framework in consecutive assessment workshops with global vendors of service-oriented platforms provides the base for developing our pattern catalog for capability diagnostics and for improvement of service-oriented enterprise architectures.
