"Why do I need to pick my own projects? We’ve heard that other companies have people allocate a percentage of their time to self-directed projects. At Valve, that percentage is 100. Since Valve is flat, people don’t join projects because they’re told to. Instead, you’ll decide what to work on after asking yourself the right questions (more on that later). Employees vote on projects with their feet (or desk wheels). Strong projects are ones in which people can see demonstrated value; they staff up easily."
