To navigate extreme uncertainty like unpredictable tariffs, Walmart's buyers use tangible, seasonal purchasing decisions (e.g., Halloween costumes) as a framework. They run detailed "what-if" scenarios on pricing, sourcing, and consumer behavior to make concrete decisions despite ambiguity.

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.

Activism isn't binary. A 'covert' approach involves expressing values through business decisions like partnerships, hiring, or amplified voices. This is a valid, often safer, alternative to direct 'overt' public statements, allowing for a spectrum of engagement based on comfort and capacity.

True corporate values are steadfast principles that guide a company regardless of the political or social climate. Values that are easily discarded when they become controversial are not core values but rather branding exercises. This inauthenticity risks significant consumer backlash when exposed.

Maximizing profits in a crisis, such as a hardware store hiking shovel prices during a blizzard, ignores the powerful economic force of fairness. While rational by traditional models, such actions cause public outrage that can inflict far more long-term brand damage than the short-term profits are worth.

Costco's business model is unique: it aims to break even on merchandise sales. This allows it to offer the lowest possible prices, building immense customer loyalty. The company's entire operating profit is derived from its annual membership fees, which represent only 2% of total revenue.

When pressured to hit quarterly targets with promotions, use a simple filter: 'Does this action increase the long-term desirability of my full-price product?' This framework helps balance immediate revenue needs with the crucial goal of protecting and building brand equity, preventing a downward spiral of discounting.

Geopolitical shifts mean a company's country of origin heavily influences its market access and tariff burdens. This "corporate nationality" creates an uneven playing field, where a business's location can instantly become a massive advantage or liability compared to competitors.
