A focus group is a group discussion with no more than ten participants and lasts 45-90 minutes. A workshop normally has more participants, takes longer time (3hours ~ 2 day), and may cover other activites including games, participatory mapping practices, or breakdown discussions. Both focus group and workshop require a facilitator to moderate the conversation.
Workshops and focus groups bring together stakeholders and enable in-depth conversations. In addition to eliciting estimates from stakeholder, the process itself encourages knowledge sharing and increases the level of ownership and engagement. Also, because to develop a spatial explicit scenarios generally requires more explanation to stakeholders, it is easier to do so in a workshop setting than through survey/interview instructions. Therefore, even the cost of trained facilitator and for bringing people together may become a barrier, such practice is likely prefered when possible.
