Facilitating PSS workshops: a conceptual framework and findings from interviews with facilitators

Recent research has emphasized the importance of workshops as a venue where planning support systems (PSS) are used in planning processes. Empirical studies of these workshops have previously largely overlooked facilitation, in particular the role of a moderator (steering the discussion) and/or a chauffeur (steering the PSS). Drawing on existing facilitation research, we identify four main categories of facilitation interventions: substantive, procedural, relational, and tool-related. We use these categories to develop a novel conceptual framework for facilitation at PSS workshops. We test and develop this framework through semi-structured interviews with eight experienced facilitators of PSS workshops in the US and the Netherlands . The interviews confirm the validity of the intervention categories, but also revealed a wider range of PSS-specific workshop outcomes. We conclude that successful facilitation of PSS workshops requires two different types of facilitation interventions: some to encourage PSS use, and others to prevent PSS domination of the group discussion. Facilitating PSS workshops is mainly about finding the delicate and context-dependent balance between these two extremes.
