Abstract: Industrial firms in Trinidad and Tobago (T&T) invest in capital projects to achieve their long-term business objectives in line with the Sustainable Development Goals as advocated by the United Nations. However, these firms have been encountering issues and challenges of poor project performance. Factors like poor workforce estimation, inefficient site layout, unreliable supply chains, lack of standard work schedules, and low worker motivation could compromise the sustainable delivery of capital projects. To address them, this paper investigates five sustainable productivity (SP) factors and derives a metric; to develop a sustainable productivity framework (SPF). Empirical evidence obtained from a recent study confirmed a strong association between practitioners’ perspectives on the factors that could improve productivity and enhance performance in T&T. The relative importance of these factors suggested that workforce standardisation, site optimisation, reliable supply chains, standard work schedules, and improved worker motivation could foster a resilient relationship among sustainable development, productivity, and performance improvements. Evidence suggest an essential consensus among practitioners that could enable an agenda geared towards the successful delivery of capital projects. Future work would verify the results and develop an industry model built upon the SPF across different industrial sectors in T&T.
