This paper reveals the application of Theory of Constraints to improve the productivity of component under consideration. Company was facing problem for delivering the targeted component after increase in demand from their customer. The past data of housing component manufacturing process, resources required, work in process inventory and raw material inventory was collected. When analyzed the past data, constraints were observed on two machines in the production line which were needed to be focused. Eliminating the bottlenecks on these resources was the solution to cope up with the increased demand and also to minimize the raw material inventory as well as work in process inventory.

The concepts described in Theory of Constraints were applied to overcome the bottlenecks on the constraint resources. The results obtained were at satisfactory level. The actual performance against the targeted level was measured and observed that productivity improved with considerable reduction in work in process as well as raw material inventories.
