The Management Top 250 ranking is based on a holistic measure of corporate effectiveness that was developed by the Drucker Institute, a part of Claremont Graduate University in Claremont, Calif. Effectiveness is defined as “doing the right things well.”
The ranking includes U.S. companies whose shares are traded on the New York Stock Exchange or Nasdaq Stock Market, and that meet criteria, described below, related to their value and prominence.
The measure seeks to assess how well a company follows a core set of principles advanced by the late Peter Drucker, a professor, consultant, author and longtime Wall Street Journal columnist. Mr. Drucker died in 2005.
These principles serve as touchstones for five dimensions of corporate performance: Customer Satisfaction, Employee Engagement and Development, Innovation, Social Responsibility and Financial Strength.
How to Read the Rankings
All scores are expressed as T-scores. They are standardized so that the typical range is 0 to 100, the mean is 50 and the standard deviation is 10.
If a company is one standard deviation above the mean (with a score of 60), its results are in the top 15% to 20% of a larger universe of companies that have been ranked by the Drucker Institute. (For the full list, please go to www.drucker.institute/2022-drucker-institute-company-ranking/.) If a company is one standard deviation below the mean (with a score of 40), its results fall in the bottom 15% to 20% of that larger universe.
If a company is two standard deviations above the mean (with a 70) or two standard deviations below the mean (with a 30), its results are in the top or bottom 2.5% of the larger universe. And if a company is three standard deviations above the mean (with an 80) or three standard deviations below the mean (with a 20), its results are in the top or bottom 1% of the larger universe.
The fact that a firm is ranked toward the bottom of the Management Top 250 does not mean that it is not managed effectively. The lowest-ranked firm on the list is still in the top 30% of a much larger group of companies that was analyzed.
Care should also be taken when comparing this year’s results with those from previous years. Because the universe of companies analyzed can expand or shrink from year to year, a change in a company’s ranking may not be as revealing as a change in its T-score.
How effectiveness is measured
Much like human health, intelligence or athleticism, corporate effectiveness is a latent variable, meaning that it cannot be directly observed. But it can be inferred from other variables that can be observed (known as indicators).
In the case of the Drucker Institute’s model, there are 34 indicators that fall under the five dimensions of corporate performance.
In building the model, no one dimension of corporate performance (or any of the 34 indicators) was judged to be more important than any other. That said, because the scoring system is compensatory, a company with average or low scores in one dimension (such as employee engagement and development) but exceptionally high scores in another (like innovation) can end up highly ranked overall.
In calculating scores, a slightly different weight was computed for each dimension based on the degree to which it was found statistically to contribute to overall corporate effectiveness. Those weights in 2022 were as follows: customer satisfaction = 20%; employee engagement and development = 19%; innovation = 22%; social responsibility = 26%; and financial strength = 13%.
Fundamentally, the model rests on the belief that all five dimensions are interrelated and influence each other over time—what social scientists call reciprocal causation.
While it might be possible to untangle those influences with longitudinal data—and the Drucker Institute has conducted research to better understand how different parts of the model relate to one another—that is not the immediate goal of this ranking. Rather, the main purpose is to provide a snapshot of overall corporate effectiveness at a point in time.
Development of the Model
Development of the model began in 2014, and included several prototype phases, with increasingly larger samples of companies included. Lawrence Crosby, then the chief data scientist at the Drucker Institute’s KH Moon Center for a Functioning Society, designed the model and, with the Drucker Institute’s Rick Wartzman and Zach First, oversaw its development.
One hundred sixty-nine indicators were analyzed before settling on 37 that went into the original model.
Beginning in 2019, extreme outliers at the indicator level in financial strength were capped so that they didn’t skew the mean—a process known as winsorization. In 2020, certain indicators in innovation were refined to bolster the model’s statistical reliability. And in 2022, all of the indicators in financial strength were given equal weight—a change from previous years—to simplify the model.
All indicators were judged against the following criteria:
- They needed to be rigorously developed based on sound statistical methods.
- They needed to capture the essence of a specific Drucker principle.
- They needed to have a sufficiently high correlation with the other indicators of the same dimension—providing assurance that each one was actually measuring the same aspect of corporate effectiveness. For example, each indicator in the area of customer satisfaction had to correlate highly with other indicators in that category.
The 34 Indicators
As in the past, the 34 indicators used in this year’s rankings are based on data obtained from a variety of third-party providers. Alice Korngold, an expert on sustainability, board governance and measurement, who is chief executive officer of Korngold Consulting in New York, developed the methodology for a portion of the Social Responsibility category.
Population of Ranked Firms
Each company listed in the Management Top 250 represents one of the highest scorers among a larger universe of 902 U.S. companies that are part of the Dow Jones U.S. Total Stock Market Index or the S&P Composite 1500 Index (or both) and also met at least one of the following criteria:
- Its shares were a component of the Standard & Poor’s 500 stock index as of June 30, 2022.
- Its market capitalization was $10 billion or greater as of June 30, 2022.
- Its revenue was $3 billion or greater as of March 31, 2022.
To be included in the ranking that is published by the Drucker Institute on its website, as well as to be eligible for the Management Top 250, a company must also have at least two valid indicators for each of the five dimensions of performance.
All data collected by the Drucker Institute was the most current available as of June 30, 2022.
Where available, data has also been obtained going back to 2012 on a year-by-year basis. This historical information provides a baseline for measuring change within each of the company’s five dimensions of performance and in terms of its overall effectiveness, as well as for spotting longer-term trends.
Scoring of Firms
Companies were scored by:
- Standardizing the raw scores on the 34 indicators to have a mean of 0 and a standard deviation of 1.
- For each dimension, averaging the company’s indicators.
- Restandardizing the average dimension scores.
- Transforming the standard dimension scores to T-scores having a mean of 50, a standard deviation of 10 and a range of 0 to 100 (except in unusual circumstances).
- Through factor analysis of those five sub-scores, computing a factor score on overall effectiveness for each firm, which, in turn, was also transformed into a T-score.
The underlying data used to compute the 34 indicators was not available in every instance for every firm being ranked. Where there was a missing field, a score was derived by computing the average of that dimension’s indicators for which the firm had a valid score. For example, the employee engagement and development category has six indicators. If a firm had a valid score for four of those indicators, the firm’s Employee Engagement and Development score became the average of the four.
When building the model, the Drucker Institute compared this way of handling missing data against another method called multiple imputation, in which a computer analysis uses all of the known variables to fill in any blanks. The two methods produced very similar results.
Testing and Validating the Model
To build the model, the Drucker Institute used structural equation modeling, a technique that combines factor analysis and multiple regression analysis to examine the relationship between measured variables and latent constructs.This approach allowed for the analysis of the entire model simultaneously, including all proposed indicators, as well as all five dimensions of corporate performance and overall corporate effectiveness.
A series of tests was run to ensure:
- Construct validity (the degree to which the indicators actually measured what they claimed to measure)
- Reliability (freedom from random error)
- Goodness of fit (between the approach being taken and the data being examined). The goodness-of-fit statistics were: Goodness of Fit Index=0.92, Adjusted Goodness of Fit Index=0.91 and Normed Fit Index=0.90.Safeguards were also built into the model so that if a single source was used in various places (such as wRatings data going into both the customer satisfaction category and the innovation category), it wouldn’t be overweighted.
In the end, the model confirmed that:
- Taken together, the five dimensions reflect a single higher-level construct (corporate effectiveness) and that each has a substantial factor loading on that construct, averaging 0.66 since 2017.
- The selected third-party metrics serve as valid and reliable indicators of those five dimensions, with an average factor loading of 0.70 since 2017.

In addition, during the prototype phase of the model’s development in 2015, the Drucker Institute worked with Payscale to field a series of survey questions to the employees of 41 companies. These questions aimed to gauge how well these employees exhibited behaviors and mind-sets that were in line with the various Drucker principles. An analysis of the results showed that companies where employees self-reported that they were adhering to the Drucker principles scored relatively high on the corresponding indicators used in the model. This convergence gave further support to the model’s validity.
Future of the Model
The Drucker Institute is committed to a process of continuous improvement. So while the principles that underlie the model are considered sacrosanct and are unlikely to change, new indicators may be introduced if they are determined to serve as better proxies for those principles.
The Drucker Institute will also continue to analyze its computational methods to ensure that they deliver fair and equitable ratings and rankings.
