SOA敏捷架构的TOGAF层次化迭代建模

针对面向服务(SOA)敏捷架构演进周期短、业务与IT对齐要求高的特点,提出一套基于开放组架构框架(TOGAF)的层次化迭代建模方法:外层迭代通过敏捷演进闭环使得企业架构能够随架构愿景的调整敏捷地实施增量化更新;内层迭代通过三维迭代矩阵建立架构模型组在需求、语义、粒度3个方面的对齐机制。对内层迭代进一步探讨了基于BPM+SOA的业务架构、信息系统架构及技术架构模型组语义对齐建模方法与典型建模过程,为SOA敏捷架构提供了一种可迭代的、阶段化交付的、业务流程与信息系统对齐的实现方案。

TOGAF Hierarchical Iterative Modeling Approach for SOA Agile Architectures

Motivated by the short evolution period as well as business & IT alignment requirement of SOA agile architectures, a hierarchical iterative modeling approach based on the open group architecture framework (TOGAF) was proposed. For outer layer iterations, an agile evolution closed loop was defined to ensure the periodical update be agilely implemented and consist with the architecture vision. For inner layer iterations, a 3-dimensional iterative modeling matrix was designed as a mechanism for the alignment of architecture models in three aspects:requirement, semantics and granularity. Furthermore, practical modeling guidelines and typical modeling process concerning the semantical alignment for business architectures, information system architectures and technical architectures based on BPM + SOA were discussed, which provides an iterative, phase delivered and business & IT aligned solution for SOA agile architectures.
