One of the books I'm reading at the moment is Robert Cialdini's 'Influence: Science and Practice'. I was reading chapter 3 about commitment and consistency and it occured to me that one could use the 'describe one thing about your role/job you like' idea possibly annually as part of the review. As the book shows, making statements and living up to them is a powerful driver as people want to be seen as consistant.
I wonder what other people's views are about this? Would it be a useful part of a review, or the unethical use of a tool of influence?
