Introduction

Enterprise Architecture Framework has four types of Architectures elements or components namely – Business Architecture, Data, Application & Technology. [BDAT]

These four types of Architectures elements are connected to ADM. ADM, the architecture development method [ADM], has three phases where the B (business), D (data), A (application) and T (technology) architectures are developed, both for the “as-is” situation and for the desired “to-be” goal.

Business architecture enables to translate or convert VALUE as an effective medium of communication and analytical framework for translating enterprise strategy into actionable initiatives- enhancing the enterprise’s capacity to enact transformation change in Today’s digital world and its technology enablers. 

The Object Management Group (OMG) provides the definition of Business Architecture as – 

“The structure of the enterprise in terms of its governance structure, business processes, and business information. In defining the structure of the enterprise, business architecture considers customers, finances, and the ever-changing market to align strategic goals and objectives with decisions regarding products and services; partners and suppliers; organisation; capabilities; and key initiatives.”
