Starbucks – Lean Operations and Digital Innovation

A Starbucks pick-up only store for mobile orders, exemplifying the chain’s order-ahead and quick service execution strategy. Starbucks revamped its retail execution by blending operational optimization with digital innovation. The company deployed Lean Six Sigma methods in stores to streamline barista workflows and reduce service times. For example, by rearranging equipment and ingredients (like moving syrup flavors, whipped cream, and drizzle closer to drink assembly), Starbucks eliminated wasted motion in drink preparation. This simple process change shaved 8 seconds off a 45-second beverage-making routine, and cut drive-thru window times by 2 seconds on average6sigma.com6sigma.com. At the same time, Starbucks leveraged technology with its mobile app for order-ahead and payment, allowing customers to place orders and skip the line. Baristas began taking orders proactively (even before payment) and the mobile ordering system was integrated into store operations, dramatically speeding up service throughput6sigma.us6sigma.us.
