SET THE SCENE:

Thank everybody in advance for their help. Ensure they feel open to be creative and that you will NOT be defensive about assumptions you may have made in designing your product or service and you will NOT be defensive about any assumptions that are brainstormed in this session.

DESCRIBE WHAT WILL BE EXPECTED OF THEM DURING THE WORKSHOP

In terms of what your business idea is, what the rules are for brainstorming, and that you will first of all look for the riskiest assumptions in each section of the Business Model Canvas, and then pick the riskiest assumptions amongst this big list.
