I’d like to share the results of one of the most interesting management experiments I’ve been a part of. At a company I worked at recently, we implemented the Single Threaded Owner (STO) model from Amazon, where you have everyone on the team report to a single leader, including product, design, and engineering. You can think of the STO model as a more extreme form of cross-functional teams, where the team has everything it needs to deliver on its mission.
