Abstract
The ISO 9000 Quality Management System which is effective at establishing and evaluating the quality system of firms has been adopted in the construction sector later than in other sectors, however, it has spread quite fast among the construction firms. As an important topic, studies on ISO 9000 arise daily. It has been noticed that, both the national and international studies are generally based on the establishment of the ISO 9000 Quality Management System and the certification process, but the process after certification has been disregarded. However, examination of the process after certification is as crucially important as the process till receiving the certificate. Moreover, an evaluation of the benefit-cost relationship of the ISO 9000 Quality Management System is quite important for both raising the awareness of firms, which are planning to be certificated, and continuation of already certificated firms. This article analyses usage and application of the ISO 9000 in the Turkish construction sector after certification by using a field study. The impacts of the ISO 9000 Quality Management System on firms and benefit-cost ratio of the ISO 9000 certification are evaluated and examined; the positive and negative aspects of the ISO 9000 certification are put forth.
