Can you handle an Agile view of Human Nature? - Motivation
Implicit in Agile methods, is a certain image of human nature. This view of human nature is prescriptive, you have to 'buy in' to this view or else somewhere along the line you will end up in conflict with yourself or with the particular agile method you are attempting. This is a real problem if you have entrenched beliefs about how people are motivated and work, less so if you are still flexible enough to let yourself be surprised.
