21ST CENTURY MANUFACTURING “NOT WITHOUT THE BASICS”
![Page 2: 21 st Century Manufacturing Not Without The Basic](https://reader031.fdocuments.in/reader031/viewer/2022030317/5a66d1577f8b9a784d8b4abd/html5/thumbnails/2.jpg)

EVOLUTION OF MANUFACTURING PROCESSES, SYSTEMS AND TOOLS
• 1950-1960 – Manual systems began migrating onto the fist computers, Order Point, Min-Max, EOQ, Scheduling Boards migrated into the first MRP systems
• 1970-1980 – Computer systems became more sophisticated (DBMOP, COPICS), MRP became MRPII
• 1990-2009 – Introduction of complex ERP systems, Internet, Extranet, new tools Lean, SCM, Six Sigma, Kanban, Kaizen, VMI, etc.

DURING THIS EVOLUTION PROCESS, SYSTEMS AND TOOLS WERE BEING
IMPLEMENTED
• New concepts were being introduced
• Companies invested in education and training
• Manufacturing came out of the closet
• Investment in Technology was being made
![Page 4: 21 st Century Manufacturing Not Without The Basic](https://reader031.fdocuments.in/reader031/viewer/2022030317/5a66d1577f8b9a784d8b4abd/html5/thumbnails/4.jpg)

MANUFACTURING SEEMS TO HAVE A COMMON GOAL
• We were all in it together
• Learning the new tools and applying these techniques
• Manufacturing began to have a common language
• The Basics were being implemented in companies from small to large
![Page 5: 21 st Century Manufacturing Not Without The Basic](https://reader031.fdocuments.in/reader031/viewer/2022030317/5a66d1577f8b9a784d8b4abd/html5/thumbnails/5.jpg)

THIS EVOLUTION HAS NEVER STOPPED
• New systems, processes and tools exist today that have been developed to meet the demands of a very complex manufacturing environment
![Page 8: 21 st Century Manufacturing Not Without The Basic](https://reader031.fdocuments.in/reader031/viewer/2022030317/5a66d1577f8b9a784d8b4abd/html5/thumbnails/8.jpg)

WORK FORCE REDUCTION
Due To Cost Pressures Companies Have Been Forced To Reduce Their Workforce
“Few Skilled Employees Wearing Many Hats”
![Page 10: 21 st Century Manufacturing Not Without The Basic](https://reader031.fdocuments.in/reader031/viewer/2022030317/5a66d1577f8b9a784d8b4abd/html5/thumbnails/10.jpg)

EDUCATION AND TRAINING
Companies have drastically cut back on the amount they spend for education and training
![Page 11: 21 st Century Manufacturing Not Without The Basic](https://reader031.fdocuments.in/reader031/viewer/2022030317/5a66d1577f8b9a784d8b4abd/html5/thumbnails/11.jpg)
11
KNOWLEDGE DRAIN
• Continued employee drain starting in the 60’s and continuing today at an alarming pace.
• This is leaving a large knowledge void especially when it comes to the basics
![Page 12: 21 st Century Manufacturing Not Without The Basic](https://reader031.fdocuments.in/reader031/viewer/2022030317/5a66d1577f8b9a784d8b4abd/html5/thumbnails/12.jpg)

DESIRE TO CHANGE
In most cases we have found that the driving reason for a company to embrace new tools and systems is when their business is facing a major threat.

THE CHALLENGE
• Implementation of advanced
• Systems
• Processes
• Tools
![Page 17: 21 st Century Manufacturing Not Without The Basic](https://reader031.fdocuments.in/reader031/viewer/2022030317/5a66d1577f8b9a784d8b4abd/html5/thumbnails/17.jpg)

ROAD BLOCKS
The Basic Systems, Processes and Tools cannot support the desired change to 21st Century thinking.
![Page 18: 21 st Century Manufacturing Not Without The Basic](https://reader031.fdocuments.in/reader031/viewer/2022030317/5a66d1577f8b9a784d8b4abd/html5/thumbnails/18.jpg)
18
REASONS FOR THE ROAD BLOCKS
• Core competencies have eroded over time and cannot support new thinking without major improvement.
• Core competencies were never in place or accurate. (Company operating on manual)
• Management and workforce desire does not match need.

ELIMINATION OF THE 7 WASTES
1. Waste of over-production– Quantity– Timing
2. Waste of waiting (delay)– Leveling of production flow– Line balancing– Lack of parts– Machine downtime
3. Waste of transportation– Improve plant layout– Decrease distance– Improve method
4. Waste of process itself– Should we produce these products?– Is this the best way?– Use of value engineering, value analysis
![Page 25: 21 st Century Manufacturing Not Without The Basic](https://reader031.fdocuments.in/reader031/viewer/2022030317/5a66d1577f8b9a784d8b4abd/html5/thumbnails/25.jpg)
ELIMINATION OF THE 7 WASTES (cont.)
5. Waste of stock– Small lots– SMED– Inventory is costly– Space reduction
6. Waste of motion– Have parts nearby– Arm's length
7. Waste of making defective products– Prevention– Poka-yoke– Find it when made– Self-inspection– Successive inspection– Process capability
![Page 26: 21 st Century Manufacturing Not Without The Basic](https://reader031.fdocuments.in/reader031/viewer/2022030317/5a66d1577f8b9a784d8b4abd/html5/thumbnails/26.jpg)

KAIZENKAIZEN: KAIZEN means improvement. Moreover it means continuing improvement in personal life, home life, social life, and working life. When applied to the workplace KAIZEN means continuing improvement involving everyone – managers and workers alike.
Policy Deployment: the process of implementing the policies of a KAIZEN program directly through line managers and indirectly through cross-functional organization.
TQM (Total Quality Management): organized KAIZEN activities involving everyone in a company – managers and workers – in a totally integrated effort toward improving performance at every level. This improved performance is directed toward satisfying such cross-functional goals as quality, costs, scheduling, manpower development, and new product development. It is assumed that these activities, ultimately, lead to increased customer satisfaction.
