For many organizations, setting up new programs typically involves consulting existing program data, talking to other expert practitioners or researchers, soliciting ideas from management and responding to funder priorities. One essential element is missing from this formula: the clients. If you are not gathering your clients’ perspectives during each step of your design process, you are missing key insights into their wants and needs that could help you create a more responsive program that clients not only want to participate in, but in which they can participate successfully. Based on the experiences of participants in the Savings Innovation Learning Cluster (SILC), this brief explores four human insights research and design methods—client interviews, client journey mapping, concept boards and prototyping—which you can use to develop more effective programs.
