LEAN MANAGEMENT
ABSTRACT
Lean has been defined in many
different ways. Following is one of the standard definition.
“A
systematic approach to identifying and eliminating waste(non-value-added
activities) through continuous improvement by flowing the product at the pull
of the customer in pursuit of perfection.”By The MEP Lean Network.
Lean manufacturing was developed by the
Japanese automotive industry, with a lead from Toyota and utilising the Toyota
Production System (TPS), following the challenge to re-build the Japanese
economy after World War II.
The concept of lean thinking was introduced to
the Western world in 1991 by the book “The Machine That Changed the World”
written by Womack, Jones, and Roos.
Lean is a philosophy that seeks
to eliminate waste in all aspects of a firm’s production activities: human
relations, vendor relations, technology, and the management of materials and
inventory.
Every Organization Must Address
• Purpose – Provide value to
customers in order to prosper.
• Process – Through smoothly
flowing value streams for design, make, and use.
• People – By engaging every
employee touching value streams (including support streams) to sustain And
improve the flow.

Kanban and MRP Combination: The
combination of these two systems is becoming quite common. An MRP system is
used for advanced planning, including long lead-time purchased materials,
adding resources, and implementing product design changes. Once the MRP has the
materials and resources “lined up,” however, Kanban is used as an execution
system, bringing with the characteristics of rapid response to customer order
and reduced inventory levels throughout the process.
