This is the guy who gets the stuff made and makes sure the supply chain is efficient and profitable. That supply chain guru is a one in a million. To find someone that adept is extremely difficult. A person like that has to eat, sleep, walk, and think about the business 8 days a week. You can't employ some random bean counter to do this.
You are correct here. However, mentioned beancounter can only become active once a product is developed; a product that hopefully is in such high demand that you barely manage to manufacture enough of it. Perhaps a novel product. An innovative product. A well thought through product. In short, a product that people really, really want and don't hesitate to buy because its so great.
This is why Mr. Cook was very much the perfect Lieutenant for Steve Jobs. Jobs was a product development guy; he wanted the insanely new, the insanely great, but did not care so much about how to manufacture those things efficiently. Mr. Cook took that burden from Steve Jobs.
And here is the thing: There is no Steve Jobs any more whose great new products need a supply chain guru. And the supply chain expert is by no means an innovation guru being able to replace the innovator just like that. Being the crazy creative product guy requires a very different mindset compared to a beancounter. Which is why they complemented each other so perfectly. Steve Jobs was very likely not that good at counting beans. I wonder why so many assume Tim Cook is a good innovator because he was good at streamlining production. I'd rather assume the opposite: his mindset - kind of a bit pedantic with numbers - made him a great beancounter. But that mindset is not particularly suitable for an innovator.
Or in other words: no one can seriously dispute that Mr. Cook played his role in making Apple what it is today. But being a great bean counter does a priori make him a good innovator or good CEO. I take it as given that Tim Cook has earned his merits in keeping Apple together when the sun fell from the skies.
But in the case of product development (Mac division) and marketing decisions (Non-upgradeable, non-repairable products. Yuck) he was not that lucky. Just check out the plethora of "jumping ship?" or "leaving the platform?" threads here at MR.
Not too long ago one could rightfully call me an Apple die-hard. However, as of today I cannot recommend any Mac. Not a single one. Too glued, too soldered, way out of proportion expensive. I really like Mac OS, and I'd hate to have to switch to some other platform. Unfortunately it very much looks like it. A bit reminiscent of a frozen over hell.
