My point is that the enterprise engineer uses, or is guided by, all of — Enterprise engineering

"A major change is occurring in the nature of work and the way that organizations relate to a rapidly changing environment. Many enterprises (and management teams) face obsolescence because of their inability to respond and adapt to this new situation. Enterprises can adapt if top management designs an appropriate information infrastructure, one which leverages human learning. A set of change processes, known as enterprise engineering, equips organizations to move towards such an infrastructure."

"Enterprise Engineering is defined as that body of knowledge, principles, and practices having to do with the analysis, design, implementation and operation of an enterprise. In a continually changing and unpredictable competitive environment, the Enterprise Engineer addresses a fundamental question: “how to design and improve all elements associated with the total enterprise through the use of engineering and analysis methods and tools to more effectively achieve its goals and objectives”..."

"The enterprise engineer must be a leader, a designer, and a synthesizer. He is a doer. He understands theory as a guide to practice. He must concern himself with human organization because the pace and success of technology are becoming more dependent on interaction with the social system and less on scientific discovery. In private as well as public research and development, such men must find ways to reverse the deterioration of ethics and efficiency. They will strengthen the information links between physical design and the public so that technology can better serve society. In the public sector they must show the level of wisdom and leadership that can co-ordinate great engineering projects with politics. They will recognise that informing the public and becoming a nucleus for crystallising public opinion is even more important in many programmes than is the underlying science."

"Enterprise Engineering is the collection of those tools and methods which one can use to design and continually maintain an enterprise."

"An enterprise architecture is a "blueprint" or "picture" which assists in the design of an enterprise. An enterprise architecture must define three things. First, what are the activities that an enterprise performs? Second, how should these activities be performed? And finally, how should the enterprise be constructed? An enterprise is a collection of enterprise activities organized into a set of business processes which cooperate to produce desired enterprise results... The architecture takes a systems view of an enterprise in which an enterprise is seen as a system which takes in inputs and produces outputs under some set of environmental constraints..."

"Enterprises are rather complex systems which have to be managed for their internal affairs, but more importantly for the many relations to the different environments in which they are operating. Today, these environments are changing much more rapidly and the need for relevant information becomes of paramount importance in the decision making processes at all levels of enterprise management. Fluctuations in market demands, technology evolution and changing regulations require very flexible enterprise operations, capable of reacting to those changes. These reactions must be based on relevant and up-to-date information which must be supported by new decision support technology. The challenges in decision support concern the identification of relevant information, easy access and intelligent use of this information. Building and maintaining the enterprise knowledge base and enabling its efficient use for decision support are major tasks of enterprise engineering."
