Negative conferencing is an intuitive method for brainstorming, also known in the literature as reverse diagramming. The classic brainstorming is turned on its head here, because it is not initially about finding new constructive approaches to solutions, but about searching for further problems, weak points and points of criticism.
Possible incidents, difficulties and negative aspects may also be invented and/or exaggerated in their effect.
In further steps, the classic brainstorming takes place in order to ultimately develop possible solutions or unique selling propositions.
