World class manufacturing is a collection of concepts that set production standards for organizations to follow. It originated from Japanese manufacturing practices and focuses on process-driven techniques like just-in-time production, streamlined flow, small lot sizes, and zero defects. The goals of world class manufacturing include improving safety, quality, cost, delivery times, and environmental impact. It utilizes principles like just-in-time, total quality management, total productive maintenance, lean manufacturing, agile manufacturing, and concurrent engineering. Agile manufacturing allows organizations to quickly respond to customer needs and market changes while controlling costs and quality.

2. World Class Manufacturing
• World class manufacturing is a collection of concepts, which set standard for production
and manufacturing for another organization to follow.
• Japanese manufacturing is credited with pioneer in concept of world-class manufacturing.
• World class manufacturing was introduced in the automobile, electronic and steel industry.
• World class manufacturing is a process driven approach where various techniques and
philosophy are used in one combination or other.

3. WCM Approach
• World class manufacturing is a process driven approach where various techniques and philosophy are used
in one combination or other.
• Some of the techniques are as follows:
• Make to order
• Streamlined Flow
• Smaller lot sizes

4. • Collection of parts
• Doing it right first time
• Cellular or group manufacturing
• Total preventive maintenance
• Quick replacement
• Zero Defects
• Just in Time

5. Focus Areas
 Safety : to eliminate accident
 Quality : to way to reach the best production quality in worldwide
 Cost : Reduce production cost by reducing wasteland loss
 Delivery : Reduce delivery time
 Environment : Reduce environmental accidents to zero and reduce negative environmental effects

6. Six Principles of world class manufacturing
 Just in time
• JIT is a complete business philosophy and a process of thinking , working and managing to eliminate waste.
 Total quality management
• It is a culture of intolerance to defects both in the processes and also information such as bills os materials and
stock records .
 Total productive maintenance
• Whenever practical , a preventative programme means that unplanned stoppages due to equipment failure are
minimized .
 Lean manufacturing
• It is the step by step elimination of waste .
 Agile manufacturing
• It is an approach to manufacturing which is focused on meeting the needs of customers while maintaining high
standards of quality and controlling the overall costs involved in the production of a product .

7.  Concurrent engineering
• It refers to an approach used in product development in which function of design engineering , manufacturing
engineering and other functions are integrated to reduce the elapsed time required to bring a new product to
the market .

8. Examples of WCM

10. • Agile manufacturing is a term applied to an organization that has created the processes, tools and training to enable it to
respond quickly to customer needs and market changes while still controlling costs and quality

11. • Agility property consisting of quickness, lightness and ease of movement.
• The ability to create and respond to change in order to profit in a turbulent global business environment.
• The ability to quick reprioritize use of resources when requirements, technology andknowlege shift.
• A very fast response to sudden market changes and emerging threats by intensive customer interaction.
• Use of evolutionary, incremental and iterative delivery to converge on an optimal customer solution.
• Maximizing BUSINESS VALUE with right sized, just enough and just-in-time processes and documentation
• An enabling factor in becoming an agile manufacturer has been the development of manufacturing support
technology that allows the marketers, the designers and the production personnel to share a common database of
parts and products, to share data on production capacities and problems-particularly where small initial problems
may have larger downstream effects
• It is a general proposition of manufacturing that the cost of the correcting quality issues increases as the
problem moves the downstream, so that it is cheaper to quality problems at the earliest possible point in the
process.

12. ATTRIBUTES OF AGILITY:
• Agility has four underlying components:
1) Delivering value to the customer;
2) Being ready for the change;
3) Valuing human knowledge and skills;
4) Forming virtual partnership.
