The [Valve Employee Handbook (2012)](https://steamcdn-a.akamaihd.net/apps/valve/Valve_NewEmployeeHandbook.pdf) lines up with what you would expect. [[Valve]] is a flat entertainment company which and it teaches about why you need to champion your own projects and collaborate. This document is an entertaining read but it also is a good reference for flat organizations and their method of Stack Ranking. It also talks about their culture of dynamic teams and decision making. It would be a good review for managers.
