Hierarchical iterative modeling approach for agile SOA

Motivated by the 2 objectives as agile evolution and business & IT alignment for agile enterprise architecture development in the pattern of Service Oriented Architecture (SOA), a hierarchical iterative modeling approach based on The Open Group Architecture Framework (TOGAF) is proposed to bridge the gap between strategy and implementation. For inner iterations, a 3-dimensional iterative modeling matrix is designed as the mechanism for alignment of architecture models in three aspects: requirement, semantics and granularity. For outer iterations, a closed-loop iterative evolution is defined to ensure that periodical update can be agilely implemented and consists with the architecture vision.
