Maybe the point is that you tend to overlook the total cost because of the small cost per event and because you are conditioned to accept the cost as a necessary evil.
IDK, but I do know that managers love those kinds of justifications.
In that case, it's a question of attitude, not (simple, ridiculously obvious) equations. Why is it called 'math', much less 'manager math', when it's really about being stingy?
