I am looking for a trustable benchmarking system for current major control system vendors like YOKOGAWA, EMERSON, ABB, SMAR, HONEYWELL, etc. by which we easily and quickly be able to focus on their weak and strenght in negotiations.
When you find one, send it to me and I'll publish it. I've been trying to get somebody to write one for Dave Spitzer's and my "Consumer Guide To..." series for several years with no takers.
