Abstract
ABSTRACT This study develops a quality function deployment model that integrates requirements and solutions through a qualitative information approach to break the current low-quality trap and ensure the improvement of the leather products manufacturing industry. This industry is a priority sector in Ethiopia’s industrial development strategy, but its performance is below par due to quality-related problems. Prior studies lack a model explaining the pathways to implement quality improvement interventions. The improvement of this industry requires qualitative assessment and is subject to uncertainty due to the linguistic preferences of decision makers. This study adopts the fuzzy Delphi method to arrive at a valid set of attributes and a fuzzy quality function deployment method to address their relationships. The findings demonstrate that 22 requirements and 16 solutions are valid measures. The top solutions include ensuring interdisciplinary design, employing process mapping, implementing quality-related standards and customer-centric operations, and establishing a quality-at-the-source attitude. Theoretical and practical implications are discussed. Graphical Abstract
