A decade ago, in the course of studying why certain high-tech companies thrived during the internet boom, we discovered something that surprised us: To shape their high-level strategies, companies like Intel and Cisco relied not on complicated frameworks but on simple rules of thumb. This was true even though they were in extraordinarily complex, challenging, and fast-moving industries. The rules were not only simple, we found, but quite specific. Typically, managers had identified one critical process—making acquisitions, for example, or allocating capital—where a bottleneck impeded growth, and then crafted a handful of guidelines to manage that process. This approach helped companies to bridge the gap between strategy and execution—to make on-the-spot decisions and adapt to rapidly changing circumstances, while keeping the big picture in mind.
We reported our findings in HBR (“Strategy as Simple Rules,” January 2001). At the time, we knew that simple rules worked in practice, but now—as a result of subsequent research that we and others have done—we have a much richer understanding of why they are effective and how to construct them.
Simple Rules in Action
In the late 1990s the government of Brazil privatized the country’s freight lines. After decades of neglect, the nation’s freight-rail infrastructure was run-down: Half the bridges needed repair; a fifth were on the verge of collapse. Twenty steam locomotives that were decades out-of-date were still in use. Rail accounted for only 20% of long-haul shipments in Brazil, compared with 80% in most countries.
ALL was spun off from the Brazilian railway authority in 1997 to manage one of the country’s eight freight lines. Its new management team took over an organization that was bureaucratic, overstaffed, and bleeding cash. Transport on the line was so unreliable that crops in the areas it served were routinely left to rot in the fields during the harvest season. Middle managers were confused about what to do, and many pushed their local agendas at the expense of the company’s overall best interests.
The team decided to adopt a simple-rules approach to the work ahead. Let’s look at how that approach helped ALL’s executives achieve alignment, adapt to local circumstances, foster coordination across units, and make better decisions.
