The association between ISO 9000 certification and financial performance

This study explores the association between ISO 9000 certification and financial performance at the organizational level in a mature quality initiative market. It extends the limited literature on quality initiatives and objective measures of financial performance. The study hypothesizes that ISO 9000 certification is associated with improvements across three dimensions of financial performance. These dimensions are operating efficiency, growth in sales, and overall financial performance. These dimensions of performance are measured using profit margin, growth in sales, and earnings per share, respectively. Based on data for a sample of 70 companies listed on the Singapore Stock Exchange over a 6-year period, the results of the study are consistent with the hypothesized effects. In particular, the results show that the extent of improvement is driven largely by operating efficiencies and suggests that firms can benefit from ISO 9000 certification if they are genuinely interested in the quality philosophy by improving their internal business processes.
