In 2022, there was a slow growth in the developing nations' GDP, but Malaysia's economy grew strongly at 8.7% due to increased activity in a number of sectors, particularly in services. Malaysia’s strong economic growth has created a higher demand for warehouse facilities and efficient warehouse operations. As a result, the need for efficient warehouse operations to reduce expenses is evident. Thus, finding the best way to structure and design warehouse operations to maximise efficiency has been a significant problem for many organisations. Consequences, such as increased waste and a negative effect on the warehouse's overall performance, are due to lack of feedback and poor selection of logistical tools to improve flow efficiency. Therefore, this article contributed to bridge the gaps of knowledge on the lean theoretical framework for warehouse operations optimisation in finished goods warehouses. The study employs a qualitative research design methodology, reviewing and analysing 7 quality journals using thematic analysis. The analysis results have classified four key factors that influence warehouse operations optimisation: warehouse layout, material flow, inventory information, and resource allocations. These critical factors of warehouse operations efficiency are significantly affected by 5 primary wastes: waiting, transportation, defect, inventory, and underutilised employees. The findings has shown that the core lean tools, VSM and 5S, should be used sequentially to eliminate waste. The tools can also be used in conjunction with other complementary lean tools to further reduce primary waste. At the end, the study's findings highlighted the framework that aligned these key elements: warehouse operations factors, waste, and lean tools as the foundation structure and design of the theoretical framework for warehouse operations optimisation through the implementation of lean methodology to enhance production and orders. This work is anticipated to establish a basis for future research in the same field as a result of its innovative discoveries.
