Profit = Revenue - Cost
(That's not what's changing, of course.) This admits two strategies: increase revenue, or cut cost.What's changing? Traditional MBA-style business is about cost reduction. Provide some static service, drive costs to zero or as close as you can get it, and hope like hell you're better at this than any of the other players. That's rapidly becoming obsolete.
Everything becomes a commodity, under this view. "We need 24 hours of programming. Get it together." Excellence (which might increase revenue faster than cost, but goes against every principle of cost-cutting) gets killed off. It's not important. Also, excellence is a bitchy problem from an MBA (polymorphic management) viewpoint because you actually need to know something fairly deep about the work and the problem domain to achieve it; whereas executive-level cost-cutting is a skill that can be applied (if to mediocre results) anywhere.
AMC has been taking the other tack: a long-term revenue-oriented approach that seems to be working quite well. Why? If you're in an oligopoly providing a commodity product or service, cost reduction often spells the difference between survival and failure. However, in this "long tail" world where there are hundreds of players competing for visibility, what you have instead is a world where almost no one gets a large proportional "slice of the pie", but the pie's much bigger. The payoff curve (between investment/quality and results) becomes convex and that favors risk, but it also favors let's-do-this excellence instead of traditional MBA-style cost-cutting.
