BT has around 1300 applications covering all aspects of its operations. The need to keep pace with an increasing rate of change in the telecommunications industry is being impacted by the ability to design and manage changes to such a large integrated applications portfolio. Computing technology and design methods are also advancing, and both old and new technologies have to work together. Achieving a balance between replacement and enhancement of applications within the constraints of money, time, and skills availability has to be carefully managed. New ways of looking at the portfolio have been developed so that a set of coherent strategies for the design and management of change can be implemented.
