"Hey, here's a nice machine, let's replace its motherboard"

Something like this just happened to one of our customers. I am aghast that this was done the way it was, but it was. One of these things where you don’t find out that there was a service issue until its “done”. For various definitions of “done”. I anticipate being on a phone call to Europe in a few hours to discuss my definition of “done” with the people who did this, and ask them if their definition of “done” includes the concept of operating correctly. All the while the customer in the process has to sit there with a non-functional machine. I have a sneaking feeling that I am going to be on a plane in the next 48 hours, flying out to fix what others broke. /sigh
