Amazon's Single-Threaded Model

Gallego's post on Amazon's single-threaded leader model — the principle that any important initiative gets a leader whose single responsibility is that initiative, with no competing demands. The model is one of the lesser-publicised reasons Amazon has been able to ship new product lines at scale: the absence of split attention at the top. For product direction the transfer is specific — if a product initiative matters, treat its leadership as a scarce resource and protect it from being thinly spread across other priorities. Short and concrete. Useful to share when someone proposes that a product director "also manage" a second unrelated initiative on the side.
