Supporting context
The article presents a case study of Walgreens' operational AI transformation, based on a 38-page report by author Kamil Banc. The methodology emphasized sequencing: cloud migration first (delivering 3x performance at one-third the cost), then demand forecasting, then robotic micro-fulfillment, using partnerships with Palantir, Zebra, and Microsoft rather than in-house builds. Practitioners can apply the core lesson that fixing internal data and process chaos before pursuing customer-facing AI reduces project failure risk. The case also highlights governance failures, including the $200 million smart refrigerator disaster and three CIOs in one year, as cautionary examples. Data quality problems reportedly remain unresolved, suggesting AI transformations require ongoing operational discipline rather than one-time fixes.
