Total quality m anagement has evolved beyond its roots in statistics and the quality control function. Today, it is believed to be a framework for`com petitive' managem ent. T he quality measurem ent instr uments for ser vice organizations developed by Parasuraman et al. have been successfully applied in many such organizations. Saraph et al. developed an instr um ent to m easure the overall organizational quality managem ent practices for both manufacturing and ser vice ® rm s. This instrum ent was tested for consistency and validity using data from US ® r ms, United Arab Em irates ® rm s and Indian ® rm s. The present study attempts to corroborate the results of the studies just m entioned. U sing data from 33 m anufactur ing and ser vice ® rm s in Singapore, inter nal consistency, criter ion-related validity and constr uct validity are tested. Additionally, the study shows how this instr ument could be used as a self-assessment tool by quality managers for continuous monitoring of quality-related perform ance . In conclusion, the instr ument developed by Saraph et al. appears to be reliable and valid for the measurem ent of the quality managem ent practices of an organization. A framework for self-assessment is also discussed.
