Abstract: The current project addresses the productivity improvement of a manual assembly line by making use of operations analysis in the framework of Lean production. A methodology is proposed that helps to improve the productivity of any production process. The methodology consists of selecting a product or product family to be studied followed by current process study. Once the existing process is documented, all the assembly tasks involved must be timed using time study techniques. Operations analysis enables the reduction of non-productive tasks and results in a set of standardized work elements along with the set of standard procedures for performing the operations. Assembly line balancing along with the associated operations analysis assists in constructing or re-configuring an assembly system, which is the key step in improving the overall performance of an assembly line. Assembly lines are one of the most widely used production systems. Productivity of a manufacturing  system can be defined as the amount of work that can be accomplished per unit time using the available resources. This project address the assembly time reduction by implementing the proposal and also it contains the cost reduction by eliminating the assembly parts and increases the productivity.
