Abstract:
There are many enterprise architecture frameworks on the market, but despite being heavily promoted with
promises of their expected benefits, in practice they have not proved to deliver expected value. The main
reason for this is IT-oriented controlled reductionist approach inapplicable for a complex enterprise. In
parallel with IT-oriented enterprise architecture business architecture was developed to support business
strategy. But, as a pure business discipline, business architecture also did not prove to deliver expected value
because, in a complex enterprise with business, which is highly dependent on IT, it is impossible to decouple
business from IT because your business is your IT. This paper will, therefore, introduce the new Business
Architecture-based Strategy-driven Enterprise architecture framework (BASE) for improving holistic
strategic alignment of the complex enterprise by supporting both formulation and implementation of the
enterprise strategy. As foundation
of the BASE framework, which will be further explored in future work,
this paper will present a business architecture-based enterprise architecture model for managing the complex
enterprise, based on business architecture also providing business-adjusted IT insights, and holistic initiative
footprinting methodology which will illustrate how to leverage business architecture and proposed EA model
to properly scope strategic initiatives already early in the process.
