Microsoft Certified Master (MCM) was established 5 or so years ago by the Product Group to help customers successfully deploy Exchange and avoid hitting problems that many customers faced. Back in those days Exchange was responsible for generating a lot of support calls. It was, and still is, a complex product, and it was too easy for customers to get themselves into a mess, and then call Microsoft hoping we would be able to fix the problems over the phone. Often this wasn’t the case, as their original design was often flawed, their implementation was poorly completed, the solution itself was too complex, or for one of many other reasons. The goal of the Ranger program was to highly train consultants and architects who would then go out and make sure the design was done right, make sure the solution was tested, make sure it really met the requirements, and ultimately, to reduce the number of customers getting themselves into situations that required a call to Product Support.
