It is, in itself, a separate engineering discipline, and one that cannot really be practiced analytically unless you understand really well the behavior of individual pieces which interact with each other. Most don't, and don't care to.
It is something which needs to be designed and tuned in place and evades design "getting it right" without real world feedback.
And you also simply have to reach a certain somewhat large scale for it to matter at all, the amount of excess capacity you have because of the available granularity of capacity at smaller scales eats up most of the need for it and you can get away with wasting a bit of money on extra scale to get rid of it.
It is also sensitive to small changes so textbook examples might be implemented wrong with one small detail that won't show itself until a critical failure is happening.
It is usually the location of the highest complexity interaction in a business infrastructure which is not easily distilled to a formula. (and most people just aren't educationally prepared for nonlinear dynamics)
