At present, an architectural style called microservices is receiving more and more attention. While it brings benefits to software projects, it also affects development organizations that use microservices architectures. This study's goal is to clarify the impact of microservices on the organization, whether these effects are beneficial or challenging for the organization. A systematic literature review is conducted and qualitative data are synthesized through meta-ethnography. Finally, seven aspects of using microservices architecture to affect an organization are identified, namely, organizational structure, autonomous team, technology/tool, organizational culture, developer, DevOps, and communication. At the same time, it is also found that although a lot of researches on microservices emphasizes that in order to fully obtain the expected benefits of microservices, it is necessary to solve organizational problems, currently there are few scholarly literatures published on organizational problems. Hence high quality grey literatures, which may be close to the viewpoint of industry, are also included in this study. Based on the result of systematic literature review and synthesis of qualitative data, four higher-order explanations have come up and an evaluation framework is proposed that helps companies evaluate and improve the adaptability of their development organizations to microservices architectures. The proposed evaluation framework provides the guidelines for development organizations adapt to microservices. Finally, based on the framework, this paper designed and conducted an industrial survey and interviews. The results of both confirmed the effectiveness of the adaptability evaluation framework proposed in this paper.
