While I will agree with you that it is his responsibility, I can tell you from an engineering perspective, what works in theory does not always live up to that standard in practical application. The switches he installed first did work only not to the extent to handle 1400 occupied rooms. I am not sure to what level they did work? Only that supposedly the switches supplied by IBM had been delivered as a suitable substitute for what was originally ordered, and they did not stand up to the demand that IBM stated they would. It is my understanding that the switch problem is fixed, if it isn't somebody please say so? I can also tell you that as an engineer designing Arliegh Burke Class Guided Missile Destroyers, a program that is almost 30 years old, it is not uncommon for systems to be installed that function in theory and in test labs that require modifications in the field. I am not so much concerned about the functional operation of the system, as that is proven, my concern lies in the lack of willingness to pursuing/demanding the ability to make it right. Let say that you install an a/c in my house, and i call you up and say Mr. Risk this thing works great except when i turn on my attic light it turns off the unit. So until you get out here and fix it I am not going to pay you for it. Now I don't go into my attic, so I don't need the light up there, so the system works good enuff to keep my house cool, but I cant find the time to meet you and let you in to fix it. so you are stuck between a rock and a hard place. you are willing to fix it, you want to get paid, but I won't let you in my house to replace the faulty relay. What do you do? in this case you take me to small claims and a judge sees right through my bullshit. But that doesn't work like that in the world of BIG BUSINESS.
