I just started reading a book by Russell Ackoff entitled "Ackoff's Best: His Classic Writings on Management."

In the very first chapter, "Our Changing Concept of the World," he says: "... by the time we find solutions to many of the problems that face us, usually the most important ones, the problems have so changed that our solutions to them are no longer relevant or effective; they are stillborn." Of course, here Ackoff is talking about the big, important problems of the world at large, but the spirit of what he's saying applies equally well to business solutions, particulalry web-based business solutions.

Very nice post by Phil Fersht, a recognized sourcing industry advisor, analyst and practitioner.
