Business process is not part of enterprsie definition
1. THE MYTH OF BUSINESS PROCESS CENTRIC EAEnterprise architecture is not business process centric as many EA practitioners believed. Frequently, the first thing of EA is to model enterprise processes. The enterprise architects are asked to model all enterprise wide business processes to know the business. The business process centric approach has frequently resulted to the EA “paralysis by analysis” because business process modeling are the sequential combination of function components and process engineers are trained to enumerate all the combination in an exhaustive approach. As a result, the architects have delivered enormous amount of business process charts to become expensive wall paper.
1.1 Business processes is not part of enterprise definition
Business processes are the solution to achieve the enterprise mission rather than as part of enterprise definition. Business Architecture is the effort to know the enterprise definition and understand its high level business processes. Enterprise definition describes the enterprise from the aspect of mission, function, information, organization, location and workload.
1.2 The two role of business processes in EA
The confusing of business process due the fact that Business processes serves two roles in Enterprise Architecture. From business architecture point of view, business process serve as the tool to achieve business excellence Business processes. From software development view, business processes serve as the requirements for business process automation.
2. BUSINESS PROCESS MUST BE REENGINEERING BEFORE AUTOMATION
Business process must be reengineered before automation
Business processes are the tool which must be reengineering before automation to avoid “Paving the cow path”.
2.1 Business processes are a function of technology evolution
3. BPR by subject experts
Instead of becoming an business process engineering expert, EA professionl relies on BPR professional for business processs reengineering in the business architecture optimization effort. BPR has been a established paradigm since 1990 after Michael Hammer, a former p
BPR has being a establish paradigm Massachusetts Institute of Technology (MIT), published an article in the Harvard Business Review. In the same year as Hammer published his paper, A similar idea was advocated by Thomas H. Davenport and J. Short (1990), at that time a member of the Ernst & Young research center, in a paper published in the Sloan Management Review.
EA ENABALE BUSINESS PROCESS REUSE VIA STANDARDIZATION
EA is the effort to enable agile and simple business process engineering via business process standardization effort to create the business process building blocks.
BUSINESS PROCESS REENGINEERING AT LOCAL LEVEL
2. Business Process Reengineering occurs incrementally in segment architecture.
Business process must be reengineered before automation to avoid the situation to “Pave the cow path”. However, instead of a “Big Bang” approach, business processes reengineering will be better off to occur at the segment architecture level rather than at the business architecture level.
Business process engineering design the optimize business process based on local culture and available technologies. It is considered as the process solution to support the enterprise mission rather as part the enterprise definition. It similar to roads in a city to take the stakeholders from one point to the other. There are many ways to take one from point A to point B. Business process reengineering is the effort to optimize the path depends on where you are and what vehicle you have. Business definition describes the enterprise strategic vision and business processes describe the business tactic. Business processes are a function of technologies evolution and it subject to localizes business processes reengineering. Enterprise definition describe the business vision and strategic direction for competition, it is not a function of business processes and technology.
Business processes must be redesign before automation to avoid the situation of “Paving the cow path”, however, instead of conduct business process engineering in a “Big Bang” approach to design business process for the entire enterprise, business process reengineering occurs at segment architecture because Business process subject to localization and it is a function of technology evolution.
