Puzzling Over Performance

Why are some companies more productive than others?

Published: Wednesday, June 29, 2016 - 16:41

In a recent post, I examined the differences in productivity across small and large manufacturing firms, and noted that there were differences across manufacturers in terms of size. But it’s also clear from the literature that productivity differs across companies even in the same industry.

Why are some companies more productive than others?

Although the differences across firms in terms of productivity is well documented (Chad Syverson, 2011), less attention has focused on what factors may account for these differences. Do these differences reflect idiosyncratic factors specific to a firm, or are they related to systematic factors that one can control and change (Bloom, et al, 2013)? Nicholas Bloom and his colleagues, for instance, found that management practices were positively and strongly related to a range of performance measures, including productivity, profitability, growth, exporting, and innovation. Management matters, of course, but how? Is operational excellence—in terms of internal characteristics such as markets, management systems, strategy—associated with better performance? Does management matter to company performance?

Strategy, operational excellence, and markets matter

Following on this work, I decided to stick my toe into that world of research and presented a paper at the 2016 Industry Studies Association meeting in Minneapolis, using a set of proprietary data collected by Core Value, which has collected data on several thousand small and midsized firms across the United States. My analysis found that factors such as strategy, operational excellence, and markets did matter.

The Core Value data provide information on self-assessments of firms on 18 dimensions of operational practices and related information on business outcomes, including productivity, gross revenue, and net income (as measured by EBITDA). I created groupings of firms into high and low performance categories based on median profit margin and sales per employee. Firms above the median were coded as 1 (high performers), and firms below median were coded as 0 (low performers). I then created a series of dummy variables based on self-assessment across 17 dimensions.

Businesses at or near best practice were coded with a 1, and all others were coded as 0. I also compared a combined management score based on 17 dummy variables and an average score (management score/17). Simple correlations between best-practice groupings on each measure and the high/low performance groupings indicated that variables such as growth, market size, customers, strategy, operations, and innovation were positive and significantly related to better performance. The chart below highlights the differences across the groups in terms of the share of firms that had above or below median performance in terms of profit margin. The blue arrows indicate those areas where the differences were statistically significant.

However, I wasn’t satisfied with these simple correlations and chi-square tests. (I’m that way.) I wanted to run a model that controlled for all these factors (and a few others), so I turned to multivariate modeling. I ran a series of logit models, and the following factors had significant—and sometimes positive—impacts on the probability of predicting high and low performance. The results are highlighted in figure 2 and identify those factors that were statistically significant related to high performance. For instance, I highlight what we found in terms of profit margin.

The importance of management

Management and markets matter. Strategy, growth orientation, operational performance, and diversified customer base are all likely to boost profit performance significantly. Size does matter. But, bigger is not always better. Size is negatively related to profit margin, but positively related to sales per employee. Market share and size is negatively related to above-average sales per employee performance. Product differentiation, strategy, and operational performance boost sales per employee.

Performance across firms varies significantly. Understanding organizational performance and the factors distinguishing high- and low-performing firms is fundamental. Management matters. However, it appears that firms do have some control over their performance. Internal practices such as strategy, operational excellence, and other factors matter. But, markets are important, too. As John Roberts (2004) suggests, strategy is a critical variable in how organizations can achieve a match between their structure, processes, and environment. He argues that this places managerial choice, and specifically strategy, as key variables in understanding performance. He suggests that while there may be no one best strategy or one best way to organize, strategy and its effectiveness depend on the environment and organization.

These findings, while suggestive, also reinforce other studies. For instance, The State of Manufacturing 2016, conducted by Enterprise Minnesota, found that “companies that operate from a strategic plan are more confident about their financial prospects than those that don’t.”

In addition, the same study held focus groups with manufacturers across Minnesota. One manufacturer stated,“Talent is one of the four puzzle pieces.... Strategy is a critical piece... continuous improvement has to be ingrained in the organization... it’s the third puzzle piece... the fourth one is the management system.”

It’s not enough to say that organizational performance varies; we also need to examine why an organization performs as it does to develop prescriptions for improvement. From a research and assistance perspective, the second question can be addressed by examining the effect of organizational structure, strategies, resources, service models, external environment factors, and internal factors such as management practices and behaviors on performance.

What can an organization’s managers, employees, and technical assistance providers do to improve performance? That’s the challenge and the opportunity.
