Facilitated meetings. The purpose of these is to try to achieve a summative effect whereby a group of people can bring more insight to their requirements than by working individually. They can brainstorm and refine ideas that may be difficult to surface using (e.g.) interviews. Another advantage is that conflicting requirements are surfaced early on in a way that lets the stakeholders recognise where there is conflict. At its best, this technique may result in a richer and more consistent set of requirements than might otherwise be achievable. However, meetings need to be handled carefully (hence the need for a facilitator) to prevent a situation where the critical abilities of the team are eroded by group loyalty, or the requirements reflecting the concerns of a few vociferous (and perhaps senior) people to the detriment of others
