Automation but from outside

To my understanding about the Process Industries automation market, Invensys really has some of the best products in the sector. No other HMI product is even close to that of Invensys. Also, many other products for data collection, logging & reporting from plant floor are also available in Invensys under different sub-groups.

But what turns out to be a surprise is, why Eurotherm has opted to go out of the organization to look for a similar product from ODS. I guess anyone can make a good justification - Eurotherm could have become an internal customer to one of Invensys' sub-group itself. This could've been really cost effective.
