Several studies have examined how the ISO 9001 Quality Management System standard affects organizational outcomes such as profits. This is the first large-scale study to examine its effects on employee outcomes such as employment, earnings, and health and safety. We analyzed a matched sample of nearly 1,000 companies in California. ISO 9001 adopters subsequently had farlower organizational death rates than a matched control group of non-adopters. Among surviving employers, ISO adopters realized higher rates of growth of sales, employment, payroll, and average annual earnings. Injury rates also declined slightly at ISO 9001 adopters, although total injury costs did not. These results have implications for organizational theory, managers, and public policy.
