EA frameworks, modelling and tools

Abstract

As enterprises can be large and complex, their architecture (EA) also tends to be large and complex. Frameworks, models and tools have been developed to address this complexity and to support enterprise architecture management (EAM) endeavours. EA frameworks use different approaches, each with its particular strengths and weaknesses. Primarily, an EA framework is a practical starting point for EAM. It is not easy to know which EA framework, or which combination of EA frameworks, is best for your organisation. For many organisations, a ‘blended’ approach might be best; this means creating an EA methodology out of parts of existing methodologies that provide the highest value in specific areas of concern.
