THE IMPACT OF LEAN SIX SIGMA TOOLS ON CUSTOMER SATISFACTION AND RETENTION: EVIDENCE FROM A BEVERAGE MANUFACTURING FIRM IN UZBEKISTAN.

Abstract

In highly competitive manufacturing markets, maintaining consistent product quality and customer loyalty has become a strategic priority. In emerging economies such as Uzbekistan, manufacturing firms face increasing pressure to improve operational efficiency while meeting rising customer expectations. Lean Six Sigma (LSS) has emerged globally as an integrated methodology that combines waste reduction and statistical quality control to enhance organizational performance. However, empirical evidence linking specific Lean Six Sigma tools to customer satisfaction and retention in Central Asian manufacturing contexts remains limited.
