This study focuses on Singapore's manufacturing-based SMEs. The framework utilised in this study, tested SMEs manufacturing technological items and their efficiency. Although numerous studies have been undertaken, further research is necessary to examine and identify the connected elements that affect the adoption of open innovation. The purpose of this study is to investigate organisational citizenship behaviours, integrative culture, managerial ties, transactional costs, and the significant role of appropriability regime in SMEs and the willingness to embrace Open Innovation. A positivist paradigm, using quantitative techniques, and a deductive research approach were undertaken for this study. The hypotheses incorporated organisational citizenship behaviour, integrative culture, managerial ties, transactional cost and appropriability regime and through statistical analyses, the research aims to quantify relationships. The primary data from SMEs was gathered via a survey. Confirmatory factor analysis was used to look at the questionnaire's Likert scale-emphasizing factor structure. Partial Least Square Structural Equation Modelling is then used to evaluate the analysis and internal consistency of the factors that were obtained (PLS-SEM). Involving SMEs in open innovation will increase the range of technical outputs and enable the development of sound, cutting-edge solutions with significant social impact. Among the advantages for society are the creation of higher-quality manufacturing and more environmentally friendly goods and services. Consequently, technological innovation is becoming a crucial component of the managerial education of tomorrow's leaders. It is possible to enhance learning capabilities and build a more constructive emphasis on managing innovation, which is necessary in the age of globalisation, by forging beneficial collaborations between diverse industries.
