The correct understanding of organizational readiness is crucial for the proper orientation of efforts and the formulation of appropriate strategies. The main objective of this research was to provide a SOA implementation model with comparative studies approach (A case study: Branches of Qarz-al-Hasaneh Mehr Iran and Resalat Banks). The pattern aimed to introduce the factors by which one could evaluate the readiness of an organization to implement a SOA. In the current research, the predictor variable included the factors relating to the SOA implementation and its components, and the criterion variable was the implementation of the SOA and its components. These factors, all, included the SOA acceptance scope, the servicing architectural maturity levels, SOA governance levels, Structural Health Assessment (SHM), management layers in the application of SOA and the use of middleware. Statistical population of this study was eventually consisted of 194 employees of Iran's Qarz-al-Hasanah Mehr Bank and 536 employees of Qarz-al-Hasanah Resalat Bank. In order to design the pattern, the components and attributes of the factors relating to the implementation of the SOA were extracted through setting up the questionnaire. The results were analyzed using SPSS®23, and AMOS®24 software. The findings of the research indicated that considering the related factors, the presentation of the SOA implementation model was desirable in Qarz al-Hasaneh Mehr Iran and Resalat Bank
