1. The document discusses the need for an alternative enterprise IT architecture due to the complexity of information provisioning overwhelming information needs, and vice versa. 2. It proposes an "archipelago" model rather than a "monolith" or uniform IT regime, with varied and dedicated computerization for different value streams rather than one standardized system. 3. The key aspects of this model are first reducing information needs, then aligning information provisioning, with interdependencies within but not between information flows and streams.
