People use the four Ps tool as a way of developing a clearer understanding about their own attitude in any given situation. It is a simple tool to use but one that people seem to find really helpful as a way of codifying and legitimising how they are feeling, and therefore better able to own and describe their mindset. It also helps people notice whether they are getting stuck in a dominating attitude over time, which in turns can cause a personal breakthrough.
