Three points on the costs of COTS

It seems to be quite popular to move away from custom build IT solutions to so called COTS - commercial of the shelf solutions. The idea being, that to software solution fulfil a functionality which long has been commoditized and standardized to such an extent that it offers no “competitive edge” nor core value to the business. For most companies and organizations the office suite would be a pretty safe bet for a piece of software which is magnificently suited for a COTS solution.
