Purpose: This study examined the role of Total Quality Management (TQM) practices in enhancing strategic decision-making and operational efficiency in Jamaican manufacturing firms. It focused on how TQM implementation influences managerial decisions and guides resource allocation through performance metrics.

Methodology/Design: A qualitative research design was adopted, with data collected from 20 participants, including managers, quality officers, and staff, using semi-structured interviews. Thematic analysis was employed to identify key patterns and themes, while ensuring trustworthiness and validity through systematic coding and ethical considerations.

Findings: The results revealed that TQM practices improved decision clarity by providing reliable data, enhanced strategic choices through employee involvement, and ensured alignment with organizational objectives via leadership commitment. Performance metrics guided resource allocation, improved operational efficiency, and fostered continuous improvement, supporting more effective strategic and operational management.

Implications: The study highlights that TQM serves as both a strategic resource and a management tool, enabling firms to make informed decisions, optimize resource use, and improve operational outcomes. Managers should strengthen TQM systems, engage employees, and align practices with organizational conditions to maximize benefits.
