I am a big fan of Herzberg's dual factor theory. I find it much more practical and actionable than the ubiqitous Maslow's hierarchy. In one of my previous jobs, I asked people in my team to make a survey to identify their motivational and hygienic factors. The surprising result for me was how much variation there was among different people. (e. g. for somebody salary was a motivational factor, for anybody hygienic one). Anyway, understanding these factors for individual team members made me much more effective manager.
