An Evaluation Method for Service-Oriented Architecture Maturity Model

Abstract

SOA maturity model was used to clarify and provide a common definition of SOA inside an organization. The model provides an abstract overview of SOA adoption by characterizing evolutionary levels. However, this study found that there is a lacking on how the previous models were evaluated to show that the model is conforming to the specification and can be implemented in the real-world environment. Therefore, this study aims to provide the evaluation method for the SOA maturity model through the verification and validation process. The Integrated Adoption Maturity for Service-Oriented Architecture (IAMSOA) model was chosen and the verification process is being performed through expert review where the study identifies the experts, determines the verification criteria, and collects and analyzes the feedback; while the validation was performed through case study by identifying the organization, determining the validation criteria, brainstorming, and collecting and analyzing the feedback. The verification results show that the evaluated model is comprehensive, understandable, accurate, and well-organized. Moreover, the validation results reveal that it is feasible and practical to be executed in the real environment. Conclusively, this study has successfully evaluated one of the SOA maturity models and shows the verification and validation process in detail which can be re-enacted in different projects and settings.
