Service-oriented architecture (SOA) maturity model is a model that can be used to guide the SOA adoption.There are several SOA maturity models that have been constructed by the previous researchers.However, most of the existing models are focused on what to evaluate rather than how to perform the evaluation.Therefore, the aim of this study is to propose a conceptual model for SOA adoption maturity evaluation.This study reviewed and investigated the existing models in order to identify the issues and current implementation of the SOA maturity model.The findings implied that there is a lack of SOA maturity models that evaluated on the SOA adoption and focused specifically on both IT and business benefits.Furthermore, the existing models also do not provide any details on how to
evaluate the maturity of SOA adoption. As a result, this study proposed a conceptual model for SOA adoption maturity evaluation that also consist of a tool to assess the maturity of SOA adoption
