The previous research on integrated management systems has varied. Most of them used a structural equation model (SEM) or consisted of a literature review. These studies have not yet presented a relationship between integration management systems at the practical level in order to improve organisational performance. These studies have not included knowledge management in their implementation. Research on knowledge management is needed in order to minimise the inefficiency of an organisation. The level of maturity of knowledge management in construction companies is only about 50% (at the practiced level). The biggest obstacle to the realisation of an integrated management system is a lack of knowledge management. Knowledge management is a key standard in integrated management and sustainability reporting. This study aims to identify the most important variables needed in the context of the development of knowledge management and integrated management systems through RII analysis, including developing a job description through RAM RACI R (Responsible), A (Accountable), C (Consult), and I (Inform).
