There are millions of jobs and everyone feels that his/her job is unique to them, their product and finally to their organization. But the fact remains that all the jobs are just combinations of 19 basic motions that are used to perform any task. The productivity is key to survival of any organizations and hence profitability. The productivity is defined as “Optimum Utilization of Available Resources”. To achieve productivity of the highest order, The consumption of all the resources viz Men, Material, Machine, Money and Methodology” have to be optimized. There are primarily three methods of determining the “Standard Time” in which a worker should perform a task: i) Maynard Operation Sequence Technique (M.O.S.T) is a predetermined motion time system that is used primarily in industrial settings to get the standard time in which a worker should perform a task. ii) Time Study is a traditional Work Measurement technique which is involved to calculate the time of the operation in an assembly line with the help of instrument (Stopwatch). iii) Taylorism, System of scientific management advocated by Fred W. Taylor. In Taylor’s view, the task of factory management was to determine the best way for the worker to do the job, to provide the proper tools and training, and to provide incentives for good performance. He broke each job down into its individual motions, analyzed these to determine which were essential, and timed the workers with a stopwatch. With unnecessary motion eliminated, the worker, following a machinelike routine, became far more productive. In the present work, comparative case study of the “M.O.S.T.” and “Traditional Time Study” was carried out for Fitment of particular parts at M/S Adithya Automotive Application Pvt Ltd. Lucknow and Assembly Line-3 at Tata Motors Ltd, Lucknow and there was appreciable decrease in time taken by M.O.S.T. in accomplishment of task in both the cases. A total decrease of 16.8% was observed in M/S Adithya Au
