The answer lies in moving to a more unified architecture model.
networks were originally stove-piped (e.g., printer sharing & minicomputer LANs for terminal servers) but precipitated out as corporate networks
availability of corporate networks made new apps economically feasible (intranets would be prohibitively expensive if you didn’t already have a network
middleware (e.g., messaging and directory) precipitating out from NOS and stove-pipes, creating markets for groupware and other innovative apps
next layer will be application services; applications that front-end legacy systems and back-end, through Stage 3 connections, e-business and decision support
Key here is that the decoupled rates of change for your applications is critical to meeting the agility across the corp. You are not going to want to change your ERP systems at the same rates that you update your e-business infrastructure.
Eg. At Intel, Sandra revs her business systems four times per year. Our SAP infrastructure gets revved maybe once or twice per year.
Decision support = anyone can get information from any of the systems. Eg. PSO, Miner and Christensen can all get info on Compaq’s latest order status.
RAD = Rapid disposable flexible applications environment. E.g. the notes application we built when we had FDIV. Built it in short timeframe and thrown away when we were done.
App bubbles represent legacy apps - don’t continue to build more silo apps and solve problems you have already solved.
Why a unified enterprise architecture?

Fully Integrated Back-end
Generation 1:Web server deployed to provide information about the company and its products and services. Vendor-automated provision of information but humans still required to accept orders.
Generation 2:Web server deployed to provide business services (e.g., order placement and order tracking). Vendor-automated provision of information and acceptance of orders, but customer still needs humans to integrate information for decision-making.
Generation 3:Internet services provide information services to integration applications. Customer-automated integration of information for better decision-making, but humans are still required to act upon decisions.
