论文摘要
企业体系结构（EA）可帮助公司使用一组从愿景到基础架构的互补模型保持其IT架构的发展与业务发展保持一致。在本文中，我们探讨了如何通过帮助验证不同的变更管理策略来利用此类模型以最佳推动这一共同发展。考虑到面向服务和云体系结构中最新技术的状态，我们建议丰富和提高有关应用程序和软件组件的各种质量（例如性能，可扩展性，安全性，技术债务）的信息的质量，以便将它们包括在企业架构的评估过程中，而不是在后来在变更实施阶段中发现它们。我们的工作在LABNAF EA框架上进行了实验，并在从工业项目中进行的部分案例研究中进行了说明。
Enterprise Architecture (EA) help companies to keep the evolution of their IT architecture aligned with their business evolution using a set of complementary models ranging from vision to infrastructure. In this paper, we explore how such models can be exploited to best drive this co-evolution by helping in validating different change management strategies. Considering state of the art techniques in service oriented and Cloud architecture, we propose to enrich and improve the quality of the information about the applications and software components on various qualities (e.g. performance, scalability, security, technical debt) in order to include them in the assessment process already at the Enterprise Architecture level rather than discovering them later in the change implementation phase. Our work is experimented on the LabNaf EA framework and is illustrated on a partial case study taken from an industrial project.
