Unleashing the Power of Distributed
Enterprise Information Systems
Trygve Reenskaug
Numerica Taskon, Oslo
Summary
Distribution of objects and components is more than a new technology; it is a new
paradigm for thinking about, designing and implementing information tools and services
in the enterprise. The good old closed systems are replaced by a vast world of cooperating objects. We only own and control a very small part of this world, the rest is
owned and controlled by others. The talk will explore the new paradigm and the deep
changes needed in enterprise organization, system architectures and personal competence
if we are to reap its benefits and meet its challenges.
