Management consultants face perennial questions about what value they add to companies. But management practices go a long way toward explaining why some businesses perform better than others, an important new analysis shows. Perhaps management consultants are onto something after all.
Surprisingly large and growing differences across businesses in wages, productivity, capital returns and worker mobility may influence income inequality and even macroeconomic growth, many recent studies show. Now it seems management practices play a big role in explaining the variations across businesses, at least in manufacturing.
The new study, by a group of well-respected researchers, is based on a Census Bureau survey of about 32,000 U.S. manufacturing plants. The survey asked such things as how frequently managers track performance indicators, how quickly underperforming employees are reassigned or dismissed, and whether managers are promoted based solely on performance and ability.
The researchers used the companies’ answers to construct a management practices index, with higher ratings for plants that do such things as monitor performance, detail targets and tie management incentives to performance. Because the survey included multiple plants within individual firms, the economists were able to examine how practices vary both within companies and between them.
They found, first, that management techniques vary widely from plant to plant. Less than 20 percent use three-quarters or more of the performance-oriented management techniques, for example, while more than a quarter use less than half of them. Perhaps most surprisingly, the authors found that a little more than 40 percent of the variation in overall management practices occurs within the same firms.
They also found that the management techniques matter — a lot. The plants practicing more structured performance-oriented management are more productive, innovative and profitable. Every 10 percent increase in a plant’s…
