Özet:

One of the most important issues in the management of businesses is performance evaluation. Measuring the efficiency organizations and providing appropriate solutions for inefficient units ensures increased productivity in units. Public and private tea companies operating in Turkey need to make strategic decisions on efficient resource utilization in order to increase their competitiveness in both the national and global markets. In this study, the increase or decrease in the efficiency of the General Directorate of Tea Enterprises (ÇAYKUR) factories, whose share in tea production in Turkey is about 50%, were investigated on an annual basis. In the research, the Malmquist Total Factor Productivity Index using exact data and Jahanshahloo, Lotfi & Valami Model using interval data were applied. The study contributes to the literature due to the limited number of studies to measure the change in efficiency of tea businesses in an uncertain environment. In addition, the results of the study are expected to assist managers and other stakeholders in the tea sector in strategy development and decision making.
