This document summarizes a company's experience hosting a hack-a-thon to address marketing challenges. The company wanted to transition to a global delivery model from a geo-centric one, improve campaign execution consistency, and develop a long-term customer journey-based marketing strategy. A hack-a-thon brought together various teams, exceeded time expectations, and identified opportunities to improve processes. Key lessons included the importance of organization, using actual processes to find flaws, and balancing strategic and tactical marketing globally and locally. As a result, several customer programs launched across geographies, CRM go-live was on track, and revenue attribution was completed.
