Business Architecture enable business transformation
Susan M. grotevant in "Business Engineering and process redesign in Higher Education : Art of Science" Terms such as Business Reengineering, Business Process Redesign, Total Quality Management, Business Transformation, Process Change Management are interchangeable. Although these terms as they have entered the popular lexicon, are often interchangeably used, together they represent a family of change methods that transform work processes and organizations in ways that range from incremental to radical. The more discontinuous the change required, the more likely that changes in organizational structure, strategies, business capabilities, and cultural norms will be necessary to capitalize on the business opportunties resulting from reengineering work processes.
James Martin has chosen to group these various methods under a larger umbrella term known as Enterprise Engineering.
"Enterprise Engineering is an integrated set of disciplines For building or changing an enterprise, its processes, and systems. It integrates the most powerful change methods and makes them succeed…Enterprise Engineering provides management with a tool box of change methods. It aims to select and integrate the most powerful methods so that management can plan and succeed with complex change while continuing to run the business.
Enterprise Engineering at its best represents the fusion of information technology and management– science and art. The term "engineering" implies a body of scientific knowledge that can be taught, and whose results can be measured and quantified. The art of managed change rests not only in the ability to assess organizational readiness and capability to implement change from a cultural, human resource, financial or technological standpoint but also in determining which combination of business engineering approaches will yield the desired results in a given organization. . Information Technology provides the infrastructure and tools, which fundamentally change organizations, but management provides the strategic business vision that transforms technology into competitive advantage. For Enterprise Engineering to succeed two questions must be answered:
What is the strategic vision for the enterprise?
How to get from here to there?
Business Transformation optimize the business performance
.Business transformation which is a management discipline for decision makers, is the effort to make business transformation. It has been an established paradigm for many years through the evolution in strategic planning, industrial engineering, operation research, BPR, TQM Enterprise Engineering. Information age business transformation is essential to take advantage of the rapid change of technology evolution as described in BPR, TQM and Enterprise Engineering and many others. It has been an on going effort for many years. System architecture is the effort to analyze system elements and design their structure, connectivity. People have applied system architecture discipline to architecture and engineering field. For business community, the discipline of system engineering and architecture appears unrelated and remote. However, system architecture is not the privilege of engineers; the system architecture principle can also be used to architect the enterprise. Adopting system architecture principle will enable a structured enterprise which becomes more efficient.
IT managers should not assume the responsibility to transform enterprise
Recently, many EA experts try to raise the stake of EA beyond IT to architect the enterprise as part on the business transformation paradigm. This direction have pretty much denied EA as an emerging paradigm and it become a redundant of business transformation paradigm.
There is a great risk for the IT manager to assume the responsibility of transforming the enterprise.
Susan grovangt  state that "System implementations make business and break through process change possible and business managers should partner with IT, not the reverse. But the reality is that when there is not clear business vision driving decisions with an organization, it is often difficult for IT to decline the leadership role in Enterprise Engineering efforts.
As a result, IT is often blamed for the failure to successfully transform an organization through implementation of systems when in fact, it is the lack of strategic business vision and leadership from the outset that led to the failure to achieve desired outcomes. Thus IT managers and organizations should not accept responsibility for driving an organization transformation without understanding the accompany risks and only after failing to recruit the necessary business leadership and vision to lead the effort."
