Facilitated GroupInterview
Most Significant Change
Participants and field staff gather personal stories of change from the people affected by a product or initiative. These stories are then reviewed in a structured, hierarchical process where groups select the most significant accounts, discuss their reasons for selection, and share the results to clarify what different stakeholders value and why.
