Abstract: The proper utilisation of available resources and appropriate time to complete a task play a crucial role to define the productivity of a line-based manufacturing industry. The high productivity is essential to meet customer demand. If the company fails to meet customer demand, it measures in terms of utilisation of available resources and time required to complete a task. An assembly line includes non-value-added activities and other wastages which lead to lower productivity. Keeping these views in this study, Maynard operation sequence technique (MOST) has been used to reduce cycle time, operation cost and maximise the utilisation of manpower after identification of lean wastages by using Toyota 3M model. The combination of lean manufacturing and MOST has been used as a technique which improves the efficiency of line by 11.23%. The statistical test has been performed by using R programming language to check the significance of applied technique.

Keywords: Maynard operation sequence technique; MOST; predetermined motion time system; PMTS; productivity; lean wastages; non-value-added activity; assembly line; standard time; line layout.
