Case Study: British American Tobacco achieves legacy application reduction and efficiency gains with Capgemini

British American Tobacco - Customer Case Study

British American Tobacco (BAT) faced the challenge of reducing its complex legacy application estate by 50% by 2017 to increase back-office efficiency and agility. To support its new Target Operating Model (TaO), BAT partnered with vendor Capgemini to rationalize its diverse application portfolio inherited from numerous acquisitions.

Capgemini implemented its Wide-angle Application Rationalization Program (WARP) methodology to analyze and map applications to business processes. The solution provided a clear 5-year roadmap, allowing BAT to confidently exceed its initial annual reduction target. The results were significant, with analysis suggesting up to 30% of applications could be decommissioned in some regions, leading to a lower total cost of ownership and decreased risk.
