A workshop is a long interactive meeting or educational session designed to create a specialised result. Workshops are longer than the typical business meeting and require more preparation beforehand. Workshops typically involve a central trainer or facilitator who sometimes works with a set of sponsors to design the sequence of presentations, plan collaborative activities, and ensure the workshop will lead to the desired result. Workshops emphasise hands-on interaction. Strategic planning often includes one or more planning workshops. Kickoffs, team chartering, requirements analysis, product design, value stream mapping, and other meetings with large collaborative deliverable may all be conducted as workshops.
