You have to find a way to measure it though. As long as you can't that it doesn't matter if there are a more holistic way to think about it (my guess is that there are but it requires a lot more data pick-up-point)
What matters is who creates profit which is easy to measure by their paycheck. What I was saying was that if want a more holistic way to approach it you will need to find a better way to measure who is involved in the sales process.
