Supporting Change Propagation in the Evolution of Enterprise Architectures

Abstract

Enterprise Architecture (EA) models the whole vision of an organisation in various aspects regarding both business processes and information technology resources. As the organisation grows, tbe architecture governing its systems and processes must also evolve to meet with the demands of the business environment. In this context, a critical issue is change propagation: given a set of primary changes that have been made to the EA model, what additional secondary changes are needed to maintain consistency across multiple levels of the EA. This paper proposes an enterprise architectural description language, namely ChangeAwareHierarchicalEA, integrated with a framework to support change propagation within an EA model. The core part of our change propagation framework is a new method for generating interactive repair plans from Alloy consistency rules that constrain the EA model.

Supporting Change Propagation in the Maintenance and Evolution of Service-Oriented Architectures

“…Previous work has shown the effectiveness of this framework in supporting change propagation within agentoriented design models [11], [12], [13], [14]. Our recent work [15] has also indicated that the framework is applicable to deal with changes in enterprise architectures.…”

Automation Processes for Enterprise Architecture Management

“…After the reconciliation step additional changes can be inferred using change propagation techniques (cf. [12], [13]). In step 5, the model is then populated again with this inferred knowledge.…”

Change Propagation and Conflict Resolution for the Co-Evolution of Business Processes

“…Dam et al 54 propose an enterprise architectural (EA) description language for change propagation within an EA model. To resolve conflicts and inconsistency while propagating the changes, the framework devises repair plans based on consistency and well-formedness rules formulated in Alloy.…”
