Without a defined and documented enterprise architecture each business project is likely to surface its own technology solution. This causes projects to cost more and take longer.
Architecture is the bridge between business and technology. It is the translation mechanism by which business needs are translated into technology solutions. The architecture can provide two things that are critical to the success of the enterprise:
o An unambiguous alignment of technology solutions with business goals
o A mechanism by which the business can express its needs to the technologists, who, in turn, can provide a means of supporting those needs
To take advantage of the promise inherent in enterprise architecture, it is necessary to clearly derive the architecture from the business strategy, drivers and critical success factors. This requires that the architects articulate the architecture in business terms before defining the technology solutions.
