The transition from an industrial to an information economy has not only dramatically increased the rate of change, it has changed the nature of change. From gradual incremental change with very infrequent once-off discontinuities (such as industry deregulation), to a climate of continuous discontinuity. Of 289 executives polled at IBM’s Advanced Business Institute in 1994, 70% defined the future of their companies as characterised by discontinuous rather than incremental change. When the cycle-time of change in an organisation’s market and environment becomes less than the cycle-time of the strategic plan, strategic planning in the traditional sense becomes meaningless. In such an environment businesses can not be reliably planned, they must be designed. There is therefore a shift from strategy as plan to strategy as adaptive enterprise design. (Haeckel, 1994)
A well designed Enterprise Architecture contains the models and the method for adaptive enterprise design. It has as one of it’s primary design goals the flexibility to deal with foreseeable change as well the built in capability to adapt to cater for enforceable change.
