COB 300 at James Madison University is a cross-disciplinary course that integrates finance, management, marketing, and operations through a semester-long team project. Working in a collaborative group, we developed a comprehensive business plan for our brand, InfiniTee, a biodegradable golf tee designed to improve sustainability on golf courses. The project required applying concepts from each discipline to evaluate the idea’s feasibility and create a well-rounded, realistic business proposal.
