Those who study advances in health care and other fields find a generation lag of about 20 years before discoveries are adopted haphazardly into standard practice. And three or four generations before an innovation, be it technical or intellectual, becomes so common that we no longer think of it as an innovation at all. Thus it is said that science proceeds by the death of scientists.
Management is no different, so its not surprising that despite many strategic transformations via IT by the mid 1970s, most officers and directors were oblivious or indifferent to IT in 1990. Yet by the turn of the century almost all were aware of ITs promise and peril. But awareness is not mastery, or even competence.
Enormous productivity gains occurred in the Industrial Age thanks to the intellectual or intangible capital of scientific management as described by Frederick Taylor. EA has the potential to contribute similarly to the Information Age.
Managing for productivity and quality is central to management practice today. But when we say efficiency or productivity most dont think of Taylor, his 1881 paper, 1911 book, or the words scientific management any more than we think of Joseph Juran, his 1928 pamphlet, his 1951 Quality Control Handbook, or the words statistical quality control when we say quality or effectiveness.
I dont know what the EA of today will be called in a few generations. I do know we will achieve the EA vision of bridging the chasm between strategy and implementation, of capturing all the knowledge about the enterprise and making it available in real time for every imaginable management need, and of having a shared language of words, graphics, and other depictions to discuss, document, and manage every important aspect of the enterprise. I know this because the enterprises that survive those next few generations will be agile, adaptable, interoperable, integrated, lean, secure, responsive, efficient, effective, and thereby more able to succeed in a world that demands we do more with less, faster, while traditional boundaries blur, and the rules of engagement change.
Succeeding in such a world requires that the enterprise masters the management of all the knowledge about itself. We are in the early stages of developing such skills. EA is the name of this emerging discipline. EA isnt the organization any more than a map is the highway, blueprints the building or the idea the invention. But maps, blueprints, ideas, and EA are tools to help us efficiently and effectively get where we want to go. Without them, were lost.
Presenting insights from leading authorities on enterprise architecture, including John Zachman, Larry DeBoever, and George Paras, this book provides organizations with a solid understanding of key concepts. Managers will be able to conduct more effective oversight of enterprise architecture activities, which will lead to more efficient management of resources throughout these organizations.
Beginning with a look at current theory and frameworks, the book discusses the practical application of enterprise architecture and best practices, and includes a wealth of resources and references. It contains the SIM's survey of IT organizations enterprise architecture activities which provides important metrics for evaluating progress and success.
