Bridging the Data Gap: Strengthening Procurement Insights from Small Producers
This case competition sought to find solutions for improving data collection and reporting from small-scale suppliers in the food supply chain, helping larger stakeholders—such as food service suppliers, universities, and governments—track progress and achieve their sustainability goals. Participants developed innovative strategies that overcame challenges such as resource limitations, technical barriers, and inconsistencies in data collection and reporting. The goal was to create scalable solutions that enhance supply chain transparency, strengthen accountability, and drive measurable progress in emissions reduction, responsible sourcing, and sustainability commitments.
The competition featured a division for both undergrad and graduate student teams to compete in. Students received $3,000 in cash prizes, access to the Sustainable Purchasing Leadership Council's online member community for one year, and a FREE copy of Management as a Calling by Andrew Hoffman.
Our inaugural competition had 8 teams, 18 judges, and 3 universities represented.

Ji Hye Kim is the award-winning chef/owner of Miss Kim in Ann Arbor, MI. Named one of Food & Wine’s Best New Chefs of 2021 and a James Beard Award Best Chef National and Great Lakes semifinalist 20, 22, 23, 24 and 25, Ji Hye aims to broaden the understanding of Korean cuisine through her cooking. At her acclaimed restaurant Miss Kim — named one of Ann Arbor’s “Most Essential Restaurants” by Eater — her seasonal menu is inspired by ancient Korean culinary traditions, and adapted with local Midwestern ingredients.
Born and raised in Seoul, Korea, Ji Hye was introduced to cooking by her mother, a talented home cook who would make large batches of kimchi every fall with seasonal vegetables, dumplings for their annual New Year’s parties, and rice cakes for the mid-autumn harvest festivals. When Ji Hye was a teenager, her family immigrated to New Jersey, and Ji Hye went on to study political science and economics at the University of Michigan, before pursuing a successful career in hospital administration. In 2008 at 27 years old, Ji Hye decided to switch to hospitality and immediately immersed herself in the industry, training across the storied Zingerman’s businesses and the Rome Sustainable Food Project. She launched her first business, a Pan-Asian food cart named San Street, which she operated for four years, in partnership with Zingerman’s.
In 2016, Ji Hye opened her first restaurant Miss Kim, which features a menu inspired by ancient Korean recipes and culinary traditions from her family, while highlighting bountiful and seasonal Midwest ingredients. Signature dishes include Royale Style Tteokbokki (rice cake batons with savory soy sauce, sautéed with shiitake mushrooms and seasonal local vegetables); Buddhist Silken Tofu Soup, a deeply flavored soup inspired by Korean Buddhist cuisine; and Fried Caramel Broccolini tossed with anchovy caramel, almonds, fried onions, and cilantro; among others. A reflection of the restaurant’s focus on highlighting the regional diversity of Korean food, Miss Kim also offers three different regional variations of BiBimBob: a pork-heavy version from North Korea that is tossed in rich pork fat and topped with tender pork belly and soy sauce; one from the mountainous region of South Korea, which features rice and potato combining to form a crispy crust as the base for locally foraged mushrooms; and a version of BiBimbob that follows the dietary restrictions of Buddhist monks, incorporating all locally sourced vegetables and no alliums. With Miss Kim’s focus on regional intricacies, ancient histories, and its spotlight on local Midwest producers, the restaurant challenges common perceptions of Korean cuisine. Her second restaurant Little Kim, focusing on vegetarian cuisine, is slated to open in Spring 2025.
Additionally, Ji Hye is committed to prioritizing fair wages, benefits and equity in the industry, and has been admitted and completed programs like James Beard Chef Boot Camp for Policy Change and Food Lab Detroit’s Fellowship for Change in Food and Labor.

As a SEAS and UM Campus Farm alumnus, Sam is thrilled to be contributing to this conference. She comes from an agricultural background having grown up on a hobby farm in Washtenaw County raising and showing dairy goats in 4-H, club and national shows. She left agriculture and moved North to get a B.Sc. in Wildlife Ecology and Management from Michigan Tech University before getting an M.S. in Environmental Justice from the University of Michigan and starting a Ph.D. at the University of Minnesota focused on Anishinaabek-centered cultural plant restorations and food sovereignty. A slew of serendipitous events throughout graduate school brought Sam back to raising dairy goats and inspired her to leave her Ph.D. program and pursue a career supporting small Michigan farmers and food producers.
When not in the CRFS office, Sam can usually be found in her garden, on a livestock farm or at one of the number shows, conventions or fairs that she participates in as an active member of the American Dairy Goat Association and dairy goat industry. She enjoys sharing her passion for agriculture with young people and sharing experiences that bring them closer to their food. So, regardless of the event, she can regularly be found with several kids — goat or human — in tow.
