Web services allows for non-monolothic thinking and planning

John Seely Brown from Xerox writes, IT systems are like monolithic blocks of concrete and are used as the reason for not changing anything. The IT system is either not changed because it is too difficult or people go in for massive redesigns – only to swear for years afterwards that they will never touch it again. Enables services to get broken down into sub-services and you rent the best sub-services from many vendors rather just one service from one vendor. Now here is a technology [web services] that can get you away from monolithic thinking. It enables you to be much more experimental and flexible. Processes can evolve over time.
