Impact of enterprise architecture on architecture agility and coherence

IT has permeated to the very roots of organizations and has an ever increasingly important role in the achievement of overall corporate objectives and business strategies. This paper presents an approach for evaluating the impact of existing Enterprise Architecture (EA) implementations. The papers answers questions such as: What are the challenges of achieving high architecture agility and coherence for development of IT initiatives, and how may these capabilities be achieved? How can architecture agility and coherence enable the attainment of IT goals that are aligned with business objectives. How can an existing EA implementation support architecture agility in response to new IT development initiatives while maintaining architecture coherence?;This paper also presents the challenges with existing EA implementations to balance the ever increasing demands of new IT requirements against the constraints of having coherent and standardized EA components. The objective of this research is to determine the relationship between the ability of an Enterprise to quickly respond to changing requirements, which is described as Architecture agility while maintaining Architecture Coherence. Industry has experienced increasing demands for both agility and coherence and there is need to successfully manage the tradeoffs between architecture agility and coherence.
