Introduction

Traditionally, managers in manufacturing companies have sought to maximize production so as to spread the costs of investments in equipment and other assets over as many units as possible. In addition, managers have traditionally felt that an important part of their job is to keep everyone busy on the theory that idleness waste money. These traditional views often aided and abetted by traditional management practices. Just-in-time (JIT) is an inventory strategy that strives to improve a business's return on investment by reducing in-process inventory and associated carrying costs. To meet JIT objectives, the process relies on signals between different points in the process, which tell production when to make the next part. Kanban are usually 'tickets' but can be simple visual signals, such as the presence or absence of a part on a shelf. Implemented correctly, JIT can improve a manufacturing organization's return on investment, quality, and efficiency. Different from JIT in that it is externally focused on the customer, lean operation starts with understanding what the customer wants. Lean production Optimize the entire process from the customer’s perspective. It is the systematic removal of waste by all members of the organization from all areas of the values stream. Lean is often referred to as a cost-reduction mechanism. Lean strives to make Lean, six sigma and lean sigma organizations more competitive in the market by increasing efficiency, decreasing costs incurred due to elimination of non-value-adding (VA) steps and inefficiencies in the processes as well as reducing cycle times and increasing profit for the organization.

Objectives of the Study

There are some particular objectives making this assignment, those are:

✓ Develop a clear sense about Just in Time and Lean operation concepts and their
