Prior to briefing, identify the “locked requirements,” or requirements that cannot be changed e.g. outputs and objectives.

Prior to briefing, break the specific requirements (the “cold” stuff) into individual parts and write down on separate pages.

Prior to briefing, create expressive variables (the “hot” stuff) that is aimed at stimulating the imagination of the team.

During briefing, use the combination of hold and cold stuff as catalyst to explore ideas. Try to combine individual and group exercises.
