Behaviour in projects is different because there's an in-built reality check in projects rarely seen in permanent organisations. Projects are essentially promises to delver something within a budget and timeline. And those promises expose everyone involved to the harsh light of reality. Behaviours that could get in the way of meeting those promises need to be dealt with, or there will be consequences.
While there are many sources of unwanted behaviour, such as personality, or thinking style, we focus on the situational sources of poor behaviour and re-design structures to clear the path for strategy delivery.
