In this case study, we explore how a $1.5B privately-held Consumer Packaged Goods manufacturer successfully navigated the challenges of a competitive market. Facing declining market share and profitability, the company struggled with ineffective promotional strategies, leading to eroded gross margins in the face of increased promotional spending. The company collaborated with Revology Analytics to develop the Promotion Effectiveness and Optimization platform using the client’s existing tech stack. This included the development of a Pricing & Promotions data warehouse in Azure and Diagnostic and Predictive Analytics capabilities for Pricing & Promotions using Tableau and R. The case study offers valuable insights into overcoming obstacles in planning and profitability, showcasing the significant improvements in retail buyer engagement, gross profit, promotional ROI, and market share.
