Purpose This study aims to critically investigate the structural relationships between total quality management (TQM), service innovation and sustainability performance in the public service sector of the United Arab Emirates (UAE). Design/methodology/approach The study employed an online survey to collect data from 400 employees working in eight selected UAE public service sector organisations located in Abu Dhabi. The collected data were analysed using structural equation modelling (SEM) to empirically examine whether TQM practices improve service innovation and, subsequently, sustainability performance in the UAE's public service sector. Findings The results show that TQM has a significant impact on service innovation and sustainability performance in the UAE's public service sector. Additionally, service innovation partially mediates the relationship between TQM and sustainability performance. Practical implications The public service sector's TQM practices and service innovation in the UAE have a much greater impact on social and environmental sustainability than on economic sustainability performance. Adopting five dimensions of TQM (following the Abu Dhabi Award for Excellence in Government Performance ADAEP model) across the UAE's public organisations will enable government departments to deliver innovative services to its beneficiaries. Originality/value This study provides a substantial contribution by addressing the gaps in the literature. Very few studies have empirically investigated the possible association between TQM, service innovation and sustainability performance in public sector organisations, particularly in developing countries such as the UAE, where the increasing efforts in TQM practices are still in their emerging stages, mainly targeting innovative service offerings and sustainable performance.
