Firms in the United States, Japan, and Germany tend to be managed especially well, while firms in Brazil, China, and India tend to be managed poorly.
Of the 20 countries in the survey, the United States received the highest overall management scores in retail, health care, and manufacturing. But US schools scored comparatively lower, coming in fourth behind the United Kingdom, Sweden, and Canada.

Great questions. We surveyed about 10,000 firms, drew these randomly from the population of firms with 100 to 10,000 employee firms, and had about 500 firms per country (over 600 in the case of India). The differences across countries given this sample size are statistically significant if they are substantial - for example the US-India gap is although the India-China gap is not (this is a much smaller gap).

on Feb 20, 2012A survey is as good as its sample. Sample size does not matter. Representativeness does. Is the sample of this study sufficiently scientifically justifiable? Several variables in the situation have also be taken into consideration for drawing such conclusions.
