ANALYSING THE SECTORS IN TERMS OF QUALITY MANAGEMENT: AHP, TOPSIS AND EDAS APPROACH

Total Quality Management (TQM) has become a critical managerial approach for businesses seeking to gain a competitive advantage in increasingly dynamic and globalized markets. In environments characterized by intense competition, enhancing job performance and employee satisfaction is essential for organizational sustainability. As such, TQM serves as a strategic framework aimed at embedding quality into every aspect of organizational operations. This study aims to evaluate the quality management performance of six major economic sectors in Türkiye for the year 2022, based on data published in 2023 by the Turkish Statistical Institute (TurkStat). The evaluation is conducted using an integrated Multi-Criteria Decision-Making (MCDM) approach that employs the Analytic Hierarchy Process (AHP) to weight the criteria and utilizes the TOPSIS and EDAS methods for sectoral performance ranking. The criteria selected for the analysis include production value, number of employees, productivity (calculated as production value per employee), turnover, and number of enterprises. According to the AHP results, production value (0.5208) and number of employees (0.2495) emerged as the most influential criteria in determining quality performance. The consistency of the AHP decision matrix was validated with a consistency ratio (CR) of 0.0993, ensuring the methodological reliability of the weighting process. The sectoral rankings obtained from both TOPSIS and EDAS methods showed strong alignment. In both evaluations, the industrial sector demonstrated the highest quality management performance, indicating its strong capacity in terms of output, workforce size, and structured quality practices. Conversely, the construction sector consistently ranked lowest, revealing significant deficiencies in quality implementation and highlighting the need for targeted improvement strategies and comprehensive project management reforms.
