Part of the brainstorming method with a room full of people is to extract insights that should have already have been gathered in research.
It lessens the likelihood that the wrong person is left to solve the problem by themselves because you have the input from others too. Even if they are the person who eventually carries selected idea through to implementation at least they’ve been exposed to insights and conversations from other ‘stakeholders’.
Often consultancies will involve more people (e.g. the customer) in the idea generation activity to bring them along on the journey. Brainstorms can definitely be done badly but also managed well by experienced facilitators.
