Reflecting on Walmart's multi-year transformation, CEO Doug McMillan identifies the most common leadership pitfall: delaying actions you instinctively know are right. He advises leaders to trust their gut and move quickly, as organizations are often more capable of handling rapid change than perceived.

To stay connected to frontline operations and customer sentiment, former EasyJet CEO Caroline McCall made it a ritual to help cabin crew collect trash on every flight. This simple, repeated act provided invaluable, unfiltered feedback from both employees and passengers that she couldn't get in the office.

A new CEO’s first few months are best spent gathering unfiltered information directly from employees and customers across the business. Avoid the trap of sitting in an office listening to prepared presentations. Instead, actively listen in the field, then act decisively based on those firsthand insights.

Sears' decline was epitomized by a CEO who felt like a "stranger" in his own stores and pursued abstract corporate strategies. In contrast, Home Depot mandated that every executive spend time on the floor, ensuring that strategic decisions were grounded in the reality of the customer experience.

The pandemic's urgency forced Walmart's leadership to accelerate its meeting cadence from a weekly/monthly rhythm to a daily one. This faster pace necessitated greater delegation, revealing the high quality and speed of decisions made by empowered associates throughout the organization.

Brainstorming cannot reveal the true friction in your customer experience. Following JetBlue's example, leaders must regularly become their own customers. This practice uncovers how high-level decisions inadvertently create flaws in the customer journey that are invisible from the boardroom.

Target's '10-4' customer service rule originated at Walmart, which went beyond just stating the rule. Walmart installed a 10-foot-long sticker on the floor as a physical measuring tool for employees. This demonstrates a powerful management principle: turning abstract cultural values into concrete, tangible, and measurable actions in the physical workspace.

Instead of a formal M&A process, Unilever's initial contact was an executive visiting The Laundress's retail store and questioning staff. This unprofessional start was a red flag, foreshadowing the chaotic post-acquisition integration and lack of process that followed.

Ford CEO Jim Farley relies on "Gemba," a Japanese principle of "go and see with your own eyes." For a major EV strategy shift, he personally inspected a torn-down competitor's car, counting fasteners and examining the wiring loom to understand the manufacturing gap firsthand before making a decision.
