I have read this interesting post in Mosaic Project’s blog,
Transactional negotiations: “it’s essentially about trading or exchanging ideas, positions or things of value”.
Transformational negotiations: “it’s about creating something new. At the point the parties enter a transformational negotiation they don’t know what the outcome will be. The outcome will be created by jointly melding and building on ideas to create new possibilities that were unthinkable at the start”. They require trust and respect.
Brainstorm meetings can be classified as transformational negotiations, isn’t it?
At the end of the day, each one of the communications, actions, activities you perform is part of a negotiation activity.
