This chapter analyzes the success factors, outcomes, and future viability of large-group methods. We have used an exploratory action research approach focusing on eight variously purposed large-group methods (AmericaSpeaks, Appreciative Inquiry, Conference Model®, Decision Accelerator, Future Search, Participative Design, Strategic Change Accelerator/ACT (IBM), and Whole-Scale™ Change). We interviewed nine leading practitioners and creators for each method, as well as six clients who had played key roles in most of these methods' execution at their organizations, asking them to reflect on the current practices and outcomes and the future of each respective large-group method, as well as the methods as a group of interventions. Based on our findings derived through theme and content analysis of interviews, we purport that both the Art (excellence in method execution) and the Artist (the right facilitator) are necessary for achieving desired outcomes of the large-group methods. We stipulate that critical elements of the Art include these five common elements (or five “I”s): having the right Individuals in the room; aiming the method at resolving the right Issue; having Intentional process (including pre-work, intra-method process, and follow-up); having the right Information in the meeting; and using the right Infrastructure (such as appropriate physical space, technology, etc.). We suggest that while these elements of Art are important, the simultaneous requisite role of the Artist is to manage the tension between the rigidity of the Art (the 5 “I”s) and the emerging human dynamics occurring between the large-group method process and the associated evolving client objectives. That is, to achieve desired outcomes, the execution of large-group method needs to be both highly premeditated and ingenious. We supplement our findings with client case descriptions and quotes from the practitioners and conclude that these large-group methods are particularly appropriate for resolving a variety of issues facing today's organizations operating under the conditions of high technology saturation, interdependence, globalization, economic downturn, and others – and that this, with some exceptions, will likely remain the case in the future. However, the future use of these methods will be challenged by the availability of Artists who can execute the methods so they lead to desired outcomes. We close with discussion of open questions and directions for future research.
