In short

Defines “business model” vs “competitive strategy,” arguing that fuzzy thinking hurts success.

Guest backgrounds

Joan Magretta, longtime editor at Harvard Business Review, explains the term’s emergence with personal computers and spreadsheets.

Key claims

Business model describes how the business runs (how you make and/or sell); strategy explains how you’ll outperform rivals.

Notable examples

Kmart and Walmart used discount retail business models by cutting costs (e.g., removing chandeliers, carpets, personal service) for lower prices. Walmart’s competitive strategy prioritized rural customers—Sam Walton placed large stores in small, ignored towns—enabling cheap land purchases, targeted buying, and preempting rivals. Kmart tried to appeal to everyone, lacking a distinctive strategy, contributing to weaker competitiveness.

Chevrolet. Together let's drive. Today, business model and strategy are among the most sloppily used terms in business. But these are separate concepts with enormous practical value. And when it comes to concepts so fundamental to success, no organization can afford fuzzy thinking.

1:12The term business model emerged when personal computers and spreadsheets became common, says Joan Magretta, a longtime editor at Harvard Business Review. Managers could use these tools to literally run the numbers to see models of how various decisions might affect the bottom line. A new business model might hinge on either a different way to make something or a different way to sell something. Take discount retailers like Kmart and Walmart for example. These pioneers applied supermarket logic to the conventional department store and developed a discount retail model which involves slashing costs by eliminating chandeliers, carpets and personal service in exchange for lower prices.

1:52While business model is a description of how your business runs, a competitive strategy explains how you will do better than your rivals. So for example, part of Walmart's unique strategy was to prioritize rural customers. In founder Sam Walton's own words, he put good-sized stores into little one-horse towns which everybody else was ignoring. And it worked! Focusing on rural areas let Walmart buy up land for cheap, target customers no one else was going after, and preempt other discount stores from entering the market in those areas. Their customer strategy thus reinforced other parts of their competitive strategy.

2:30In contrast, Kmart tried to appeal to everyone, and that's not a distinctive strategy. So while they may have a good business model, without a clear strategy, they've struggled to stay competitive. So to get ahead of your rivals, you not only need a good business model and a clear strategy, you also need a clear understanding of the difference between the two.
