Abstract:
This study examines the relationship between Total Quality Management practices and
Corporate Sustainable Development in manufacturing companies located in the
Nuwara Eliya District, with a particular emphasis on the mediating role of Green
Innovation. The first objective of this study is to assess the levels of Total Quality
Management (TQM) practices, corporate sustainable development, and gteen
innovation in selected manufacturing companies in the Nuwara Eliya District. ln
response to the increasing global and local focus on sustainable industrial practices, the
research investigates how core TQM elements such as leadership, customer focus,
strategic planning, process and knowledge management, supplier quality management,
and human resource management can contribute to achieving environmental, social,
and economic sustainability within the manufacturing sector.
The concept of green innovation, comprising green technology innovation and green
management innovation, was introduced as a mediating variable to explore whether
innovative environmental practices strengthen the impact of TQM on sustainable
outcomes. Data were collected through a structured questionnaire administered to 150
respondents selected from various manufacturing firms operating in the Nuwara Eliya
District. The data analysis involved descriptive statistics, correlation, and mediation
analysis using appropriate statistical tools.
The finding for the first objective revealed that TQM practices, green innovation &
CSD were perceived at very high levels. The findings reveal that TQM practices are
significantly and positively related to corporate sustainable development. Moreover,
green innovation was found to play a partial mediating role in the relationship,
suggesting that TQM practices become more effective in promoting sustainability when
complemented by green innovation strategies. These results emphasize the importance
of integrating green thinking into quality management systems and provide empirical
evidence to guide manufacturing companies in Sri Lanka toward more sustainable
operational models.
