Of course the GUI only tells part of the story. Once the front end is right, it is critical that the system is able to deliver on your control inputs. We’ve all likely been in the position where we have used or demonstrated and something has not worked (usually when the CEO is in town). The vast majority of our control modules are written in-house, and those that are not are thoroughly tested and signed off in our own sandbox environment before they go near any of our software or systems. In short, our stuff pretty much works first time: handy when your deadlines are tight and the heat is on.
