Abstract: Maintenance is a crucial function in any organisation, as it ensures that equipment and systems are functioning efficiently and effectively, and this study investigates how Lean and Teoria Reshenija Izobretateliskih Zadatch (TRIZ) methodologies can enhance maintenance practices. Initially, the study reviews relevant literature on Lean and TRIZ individually to evaluate their applicability to maintenance. Next, the research explores how Lean and TRIZ practices complement each other and how integrating them can improve maintenance processes. Lean is known for reducing process waste, while TRIZ provides a systematic approach for innovative problem solving. The study reveals that there is a 50% overlap between TRIZ principles and various Lean techniques, indicating the potential for synergy between the two methodologies. In conclusion, this study provides a promising solution for organisations looking to optimise their maintenance processes by leveraging the benefits of both Lean and TRIZ methodologies.
