Lean Manufacturing

 

While defining Lean manufacturing, James P. Womack, Daniel T. Jones and Daniel Ross in their book titled “The Machine That Changed the World” quoted that "Lean Production is lean because it uses less of everything compared with mass production - half the human effort in the factory, half the manufacturing space, half the investment in tools, half the engineering hours to develop a new product in half the time. Also it requires keeping far less than half the needed inventory on site, results in many fewer defects, and produces a greater and ever growing variety of products.”

 

The recent shift in manufacturing paradigm due to relentless pursuit of lean manufacturing by business world introduced a new dimension in competition. Your competitor can produce exactly what a customer wants, when he wants it and at the price he wants with zero waste.  

Lean manufacturing is all about minimization of all resources used in various activities of the enterprise to create value to customers through high quality products and/or services. It is a systematic approach to reduce costs, lead-time and relentlessly eliminating non value-added activities. It helps us to identify and eliminate waste through continuous improvement techniques.

 

Lean manufacturing created by Henry Ford and perfected by Toyota identified seven sources of waste:

1.       Process

2.       Methods

3.       Movement

4.       Product defects

5.       Waiting time

6.       Over Production

7.       Inventory

 

According to researchers Steven Spears and H. Kent Bowen, a standardized way of thinking at Toyota starts with four rules.

 

1.       Structure every activity

2.       Clearly connect every customer / supplier

3.       Specify and simplify every flow

4.       Improve through experimentation at the lowest level possible towards ideal state

 

Implementation of Lean Manufacturing effort based on four rules mentioned above needs a winning lean strategy. We have developed our strategy based on experience gained in implementation of lean manufacturing by Fortune 500 companies.

Our Approach

Our approach in implementing Lean Manufacturing is outlined below:

 

1.       Form a Executive Lean Council after obtaining strategic direction, priorities and resources from top management

2.       Develop scope and boundaries of lean manufacturing

3.       Document current status

4.       Train all employees in principles of lean manufacturing and communicate shared vision

5.       Conduct training in value stream mapping, visual work place organization, set-up reduction, cellular / flow manufacturing systems, pull / Kanban systems, Andon Card, TPM, TOC, quality at source, process capability, PDCA, Poka Yoke, line balancing, activity sampling and methods improvement

6.       Create Value Stream Maps

7.       Identify gaps between desired and existing state

8.       Select appropriate pilot project to implement

9.       Form Core Lean Council

10.    Initiate, guide and steer the process of waste elimination through continuous improvement

11.    Sustain the movement till end result achieved

12.    Develop more lean champions and repeat the process from step 3

 

 

We subscribe to the ancient view that every individual has infinite potential. When this potential is nurtured through education and training, nothing prevents the organization in achieving break through results. That is what we strive to achieve.
