A review of the Williams College Affinity Network Dashboard project, including SQL data extraction, statistical analysis using R, and dynamic, Tableau-based visualizations. Goals of the project were to calculate the size and capacity of student affinity groups, assigning a personal network value to each alumnus. This allows us to pinpoint high-capacity networks that warrant attention from development staff, infusing greater socioeconomic diversity into prospect portfolios. We are also able to identify alumni of influence and facilitate personal connections with hard-to-reach prospects.
