Industrial and Manufacturing Engineering
Sprout Up—in San Luis Obispo—is currently a non-profit organization that teaches free environmental science education to first and second graders around the San Luis Obispo area. Due to recent circumstances, Sprout Up will soon be losing its non-profit status, and therefore they will be losing their funding as well. Their problem is that they need a stable annual fundraiser that will help the organization continue to provide free services to local elementary schools as a Cal Poly club rather than a non-profit. Multi-criteria analysis techniques were used to determine what would be the best solution to their problem and found …
