> The "more to the secret sauce" is the structure of the company. Valve is flat.
I'm too lazy to dig up references, but there have been semi-exposés over the years by ex-employees stating that Valve's flatness was anything but. Namely, in the absence of formal hierarchy an informal one will inevitably arise, and can be equally constraining and pathological, without the benefit of having known avenues for redress. To be sure, formal procedures can also be window-dressing: it's a balancing act, and not an easy one. I'm just skeptical of ascribing too much benefit to lack of structure.
My understanding is that the emergence of informal hierarchy can actualy be the feature; The problem being addressed being the rigdity of formal hierarchies in a changing environment. As long as informal hierarchies emerge and die according to circumstances, that can be a win.
