A huge chunk of an MBA'a job is to play a hostile asymmetric game against their employees (where their productivity has somewhere between negative value and positive sentimental value to them and their wages have negative value to you), and an approximately zero sum game against competitors, and a more neutral zero sum game against their customers trading quality and advertizing for price. These sorts of games are complicated and winning strategies change as the playing field evolves and your opponents change tactics. A working strategy could quite legitimately be described as "it simply works, don't ask why" because no one has quite figured out why. And different strategies will work better or fail miserably depending on who the other players are.
