Wisdom From Walmart

Author: David Perell URL: https://www.perell.com/blog/wal-mart One-line: David Perell’s distillation of Sam Walton and Walmart — drawn largely from Walton’s autobiography Sam Walton: Made in America — on competitiveness as relentless self-correction, frugality as Customer Obsession, the math of Discounting, Vertical Integration in logistics, and pushing authority to the front lines.

Key claims

Origins and competitiveness

• Sam Walton, the founder of Walmart, created more wealth in the 20th century than almost anybody else. By way of scale: Procter & Gamble sells more product to Wal-Mart than it does to the whole country of Japan.
• After leaving the military, Walton took over his first variety store in 1945 at age 26 — a Ben Franklin in Newport, Arkansas, bought with a $20,000 loan from his father-in-law and $5,000 in Army savings. The store earned $80,000/year at purchase; under Walton it grew to $225,000 in revenue in just three years.
• Walton cared about winning retail, not about being right. He was so obsessed with retailing that he wasn’t worried about destroying his old beliefs when new evidence contradicted them — a stance of constant Self-Criticism. The framing question: how often can you change your mind?
• David Glass (who later succeeded Walton as CEO) put it: “Two things about Sam Walton distinguish him from almost everyone else I know. First, he gets up every day bound and determined to improve something. Second, he is less afraid of being wrong than anyone I’ve ever known. And once he sees he’s wrong, he just shakes it off and heads in another direction.”
• Walton soaked up wisdom from everybody — competitors and entry-level associates alike — and was only concerned with what competitors were doing right, not what they were doing wrong. He believed he could learn from every store and every employee (a Spirit of Humility).
• One associate’s account of being interviewed by Walton: “he proceeds to extract every piece of information in your possession. He always makes little notes. And he pushes on and on. After two and a half hours, he left, and I was totally drained.” Perell connects this information-extracting habit to Gordon B. Hinckley, whose breadth of knowledge across medicine, law, building trades, and law enforcement came from relentlessly grilling experts wherever he traveled.
• The Hypermart failure did not discourage Walton from launching future experiments. Earlier, large “Family Centers” earned $2 million/year per store — unthinkable for small towns at the time — and taught Walton the advantages of scale.

Frugality as customer obsession

• Walton’s philosophy of Wal-Mart was simple: sell the highest quality goods at the lowest possible prices. Frugality was built into his DNA.
• On staying cheap even at $50 billion-plus: “We exist to provide value to our customers, which means that in addition to quality and service, we have to save them money. Every time Wal-Mart spends one dollar foolishly, it comes right out of our customers’ pockets.” Every dollar saved put them one step ahead of the competition. (A pure statement of Customer Obsession.)

The math of discounting

• By increasing volume Wal-Mart lowered prices; lower prices grew market share; greater market share built structural advantages that kept the virtuous cycle turning. (Discounting as flywheel.)
• Walton’s worked example: “say I bought an item for 80 cents. I found that by pricing it at $1.00 I could sell three times more of it than by pricing it at $1.20. I might make only half the profit per item, but because I was selling three times as many, the overall profit was much greater.”
• “This is really the essence of discounting: by cutting your price, you can boost your sales to a point where you earn far more at the cheaper retail price than you would have by selling the item at the higher price. You can lower your markup but earn more because of the increased volume.”
• To Walton’s surprise, there was far more business in small-town America than anybody — including Walton — had ever dreamed of (Small Towns).

Operations: logistics, overhead, and the front line

• To improve efficiency, Walton focused on a single metric: the ratio of sales to inventory (Metrics).
• Wal-Mart took control of its distribution and logistics channels. This Vertical Integration gave it an edge over competitors reliant on third-party suppliers: the gap from a store placing a computer order to receiving replenishment averaged only about two days, vs. five or more for competitors. Shipping cost ran under 3% of goods vs. ~4½–5% for competitors — “if we both sell the same goods for the same price at retail, we’ll earn 2½ percent more profit than they will right there.”
• To fight bureaucracy, Wal-Mart kept general office expense below 2 percent of sales — unchanged “from five stores to two thousand stores,” even after absorbing the cost of computer and distribution-center support.
• Walton believed in pushing responsibility and authority down: “The bigger we get as a company, the more important it becomes for us to shift responsibility and authority toward the front lines, toward that department manager who’s stocking the shelves and talking to the customer.” (Accountability, Leadership.)
• This decentralization was nested within the larger mantra: focus on the customer. Roberto Goizueta (Chairman & CEO of Coca-Cola) on Walton: “Sam Walton understands better than anyone else that no business can exist without customers. He lives by his credo, which is to make the customer the centerpiece of all his efforts.”

“Every time Wal-Mart spends one dollar foolishly, it comes right out of our customers’ pockets.”

“By cutting your price, you can boost your sales to a point where you earn far more at the cheaper retail price than you would have by selling the item at the higher price.”

“Shift responsibility and authority toward the front lines, toward that department manager who’s stocking the shelves and talking to the customer.”

How it connects

• Sam Walton / Walmart — the subject; this piece is a compact source for Walton’s operating philosophy, drawn from Sam Walton: Made in America.
• Self-Criticism / Spirit of Humility — being “less afraid of being wrong than anyone,” learning from every competitor and associate. Perell ties the same trait to Charles Darwin (thinking in reverse) and Gordon B. Hinckley (relentless cross-disciplinary curiosity).
• Customer Obsession — frugality reframed as saving the customer money; the Goizueta and Walton quotes.
• Discounting — the lower-markup-higher-volume math as the structural engine of Wal-Mart’s flywheel.
• Vertical Integration — owning distribution/logistics for a durable cost-per-unit advantage.
• Small Towns / Metrics / Accountability — the under-served small-town market, the single sales-to-inventory metric, and front-line authority.

• Wal-Mart’s strategy of pushing down responsibility was nested within a more important mantra: focus on the customer. Customer Obsession
• To differentiate itself against the rising competition, Wal-Mart took control of its distribution and logistics channels. This Vertical Integration gave the company a competitive advantage over competitors that relied on third-party suppliers. Playbook: Supply Chain
• __Here’s the simple lesson we learned—which others were learning at the same time and which eventually changed the way retailers sell and customers buy all across America: say I bought an item for 80 cents. I found that by pricing it at $1.00 I could sell three times more of it than by pricing it at $1.20. I might make only half the profit per item, but because I was selling three times as many, the overall profit was much greater. Simple enough. __

• By increasing their volume, Wal-Mart lowered prices; by lowering prices, they increased market share, and by increasing market share, they built structural advantages which allowed this virtuous cycle to perpetuate. Discounting Here’s Walton:
• Walton’s philosophy of Wal-Mart is simple: sell the highest quality goods at the lowest possible prices. Frugality is built into Walton’s DNA.
• After leaving the military, Walton took over management of his first variety store in 1945, at the age of 26. Aided by a $20,000 loan from his father-in-law and $5,000 he had saved from his time in the Army, Walton purchased his first variety store in Newport, Arkansas. The store was called Ben Franklin. At the time of purchase, the store earned $80,000 per year. With Walton at the helm, the store grew fast to $225,000 in revenue in just three years.
• Walton’s appreciation for the value of a dollar was crucial for Walmart’s success:
• “I’m asked why today, when Wal-Mart has been so successful, when we’re a $50 billion-plus company, should we stay so cheap? That’s simple: because we believe in the value of the dollar. W__e exist to provide value to our customers, which means that in addition to quality and service, we have to save them money. Every time Wal-Mart spends one dollar foolishly, it comes right out of our customers’ pockets.____ Every time we save them a dollar, that puts us one more step ahead of the competition—which is where we always plan to be.” Customer Obsession

• Walton held a strong belief in the importance of pushing down responsibility and authority. Walton continues: Accountability Leadership

• Walton soaked up wisdom from everybody he could — from competitors to Wal-Mart’s entry-level associates.
• To Walton’s surprise, he discovered that there was much, much more business in small-town American than anybody — including Walton — had ever dreamed of. Small Towns
• “Sam Walton understands better than anyone else that no business can exist without customers. He lives by his credo, which is to make the customer the centerpiece of all his efforts. And in the process of serving Wal-Mart’s customers to perfection (not quite perfection, he would say), he also serves Wal-Mart’s associates, its share owners, its communities, and the rest of its stakeholders in an extraordinary fashion—almost without parallel in American business.”
• “2 percent of sales should have been enough to carry our buying office, our general office expense, my salary, Bud’s salary—and after we started adding district managers or any other officers—their salaries too. Believe it or not, we haven’t changed that basic formula from five stores to two thousand stores. In fact, we are actually operating at a far lower percentage today in office overhead than we did thirty years ago, and that includes tremendous expenses for computer support and distribution center support—though not the actual cost of running the distribution centers. Really, it includes everything that we supply centrally in the way of support for the stores.”
• Walton writes:
• To fight bureaucracy, Wal-Mart kept below a 2 percent general office expense structure. As Walton instructed:
• “As David Glass says about me, once I decide I’m wrong, I’m ready to move on to something else.”
• “The bigger we get as a company, the more important it becomes for us to shift responsibility and authority toward the front lines, toward that department manager who’s stocking the shelves and talking to the customer. When we were much smaller, I probably wasn’t as quick to catch on to this idea as I should have been.”
• Walton was only concerned with what his competitors were doing right — not what they were doing wrong. Walton believed he could learn from every store and every employee. Spirit of Humility
• David Glass, who would later replace Sam Walton as CEO of Wal-Mart, described Walton’s commitment as such:
• Describing Sam Walton, Roberto Goizueta, the Chairman, and CEO of Coca-Cola once said:
• “The gap from the time our in-store merchants place their computer orders until they receive replenishment averages only about two days. That probably compares to five or more days for a lot of our competitors, which don’t ship as much merchandise through their own network. The time savings and flexibility are great, but the cost savings alone would make the investment worthwhile. Our costs run less than 3 percent to ship goods to our stores, while it probably costs our competitors between 4 ½ to 5 percent to get those same goods to their stores. The math is pretty simple: if we both sell the same goods for the same price at retail, we’ll earn 2 ½ percent more profit than they will right there.”
• __But this is really the essence of discounting: __by cutting your price, you can boost your sales to a point where you earn far more at the cheaper retail price than you would have by selling the item at the higher price. In retailer language, you can lower your markup but earn more because of the increased volume.”
• __“If you’re interested in “how Wal-Mart did it,” this is one story you’ve got to sit up and pay close attention to. Harry was selling ladies’ panties—two-barred, tricot satin panties with an elastic waist—for $2.00 a dozen. We’d been buying similar panties from Ben Franklin for $2.50 a dozen and selling them at three pair for $1.00. Well, at Harry’s price of $2.00, we could put them out at four for $1.00 and make a great promotion for our store. __
• Only then did Walton learn about the advantages of large stores. Walton called them “Family Centers.” They earned $2 million per year in sales per store, which was unthinkable for small towns at the time.
• To improve efficiency, Walton focused on a single metric: ratio of sales to inventory. Metrics
