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.

Walmart's primary view of AI is offensive, focusing on growth opportunities like creating a personalized, multimedia e-commerce experience. This shifts the narrative from AI as merely a defensive efficiency tool to a strategic growth driver, fundamentally changing how people shop.

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.

The AI job impact conversation has moved beyond tech. Walmart's CEO expects AI to change every job and plans for flat headcount over the next three years, even while growing the business. This signals a new mainstream corporate playbook focused on productivity over job creation.

A study found that CEOs trained to prioritize shareholder value deliver short-term returns by suppressing employee pay. This practice drives away high-skilled workers and cripples the company's long-term outlook, all without evidence of actually increasing sales, productivity, or investment.

To truly build a people-first culture, give the head of HR (rebranded as 'Chief Heart Officer' to change perception) more political clout and decision-making power than the Chief Financial Officer. This organizational structure ensures that employee retention and happiness are prioritized over pure financial metrics, leading to long-term stability and success.

To manage an overwhelming list of necessary business changes, Walmart's leadership began by clearly articulating what would remain constant: its core values. This provided a stable foundation, making the subsequent, widespread transformation feel more manageable and less threatening for employees.

A sustainable competitive advantage is often rooted in a company's culture. When core values are directly aligned with what gives a company its market edge (e.g., Costco's employee focus driving superior retail service), the moat becomes incredibly difficult for competitors to replicate.

To fund crucial investments in wages, prices, and e-commerce, Walmart's leadership, with board support, intentionally reduced its operating income from over 6% to just over 4%. This shareholder-funded investment was a deliberate, multi-year strategy to future-proof the business.
