Requirements by Collaboration

Gottesdiener's six-P framework is one of those rare ideas that actually sticks — Purpose, Participants, Principles, Products, Place, Process gives facilitators a mental checklist they'll use in the room. The emphasis on human dynamics over purely technical documentation tools is what makes this book stand apart from competitors. It predates agile's mainstream adoption so the workshop structures can feel heavyweight, but the core facilitation wisdom holds up well.
