  2. 2. TOTAL QUALITY MANAGEMENT (TQM) ‘Total’ : Made up of whole ‘Quality’ : Degree of excellence ‘Management’ : Act of handling, controlling, directing, staffing an organisation. “Maximum user satisfaction at minimum cost” “TQM is both a philosophy and a set of guiding principles that represent the foundation of a continuously improving organisation.” Quality is determined by the combined efforts of various departments such as design, process planning, engineering, purchase, production and inspection. The golden rule of TQM “Do unto others as you would have do unto you”.

  8. 8. 5-S“5 S is a technique that results in a well-organized workplace complete with visual controls and order.” Developer- „Iwao Kobayashi‟ Sort (SEIRI) : Clear unnecessary items from work area. Straighten/Set in order (SEITON) : Organize work area in an orderly manner. Shine (SEISO) : Clean work area. Standardize (SEIKESTU) : Maintain work area cleanliness. Sustain (SHITSUKE) : Maintain self-discipline in work area.
  9. 9. 5-S There’s no second chance to make the first impression
  10. 10. 5-STOYOTA ASSEMBLING PLANT
  11. 11. 5-S OBJECTIVE Increase the Storing places. Create and preserve standards. Reduce unproductive times. Readjust the location. Reduce the document search time with 20%.

  15. 15. 5-S
  16. 16. 5-S BENEFITS OF IMPLEMENTATION It reduced the idle time & fatigue to workers. Reduction of wastage of material Improvement in quality & Productivity Punctuality, commitment & discipline Improved effectiveness of employees Reduction in Non- Value-Added Activities Following cost gets decreased- Record keeping & administrative cost Deterioration cost Handling cost
  17. 17. KAIZEN „KAI „: Change ; „ZEN‟ : Better „Changes for better‟ or „ Continous Improvement‟ Masaaki Imai – developer of Kaizen “Kaizen is a Japanese word for the phylosophy, that defines management’s role in continously encouraging & implementing small improvement involving everyone.” Kaizen makes the process more efficient , effective and adaptable. Kaizen focuses on simplication of complex process by breaking them down into their sub-process and then improving them
  18. 18. KAIZENMANUFACTURING OBJECTIVES
  19. 19. KAIZEN Key Elements of Kaizen foundation of Kaizen Quality  Team Work Effort  Personal Involvement of Discipline all employees  Improved Willingness to Morale Change  Quality Circles Communication  Suggestions For Improvement
  20. 20. KAIZENJOB FUNCTIONS AS PERCIEVED BY JAPANESE MANAGERS
  21. 21. KAIZEN KAIZEN IMPROVEMENT FOCUSES ON Value added & non-value  Documentation of standard added work activities. operating procedures Muda: wastes  5-S frame work 1. Over Production  Better Communication through 2. Delay visual displays- posters, bulletins. 3. Transportation  Just In Time Principles 4. Inventory  Poka – Yoke : to prevent or 5. Defective Parts detect errors 6. Wasted Motion  Team Effort on Problem solving, 7. Processing conflict reduction & Principles of Material communication. Handling
  22. 22. KAIZENKAIZEN : SMALLSUGGESTIONS •Work Improvement •Environment Improvement •Process Improvement •Machine capability Improvement •Quality Improvement •Customer Service Improvement An example of a Kaizen type improvement would be the change in color of a welding booth from black to white to improve operators visibility

  24. 24. JUST IN TIME (JIT) “JIT is manufacturing philosophy that produces necessary units, with the required quality, in the necessary quantities, at the last safe moment.” Eliminates waste of time, labour and storage space. It’s a “pull” system of production: actual orders provide a signal when to manufacture. Non-value-adding activities are removed for the purposes of :  Reducing Cost  Improving Quality  Improving Performance  Improving Delivery Adding Flexibility  Increase innovativeness
  25. 25. JUST IN TIME (JIT)
  26. 26. JUST IN TIME (JIT) Advantages of JIT Limitations of JIT Reduction in storage  Little room for space mistakes Less working  Production is very capital reliant on Less likelihood of suppliers stock perishing  No spared finished Avoids the build up product to meet of unsold finished the expected product demand
  27. 27. KANBAN„KAN‟ : Card ; „BAN‟ : SignalJapanese term for "visual record”Coined by : Taiichi OhnoThe Kanban card is “A message that signals depletion ofproduct , parts or inventory that when received willtrigger replenishment of that product, part or inventory.”Bernstein identifies as “a highly efficient and effectivefactory production system”.No. of kanbans =

  29. 29. POKA- YOKE „POKA‟ – „mistake‟ ; YOKERU – „Proofing‟ Developer: Shigeo Shingo (1960)- The industrial engineers at Toyota. “Techniques that help operators avoid mistakes in their work caused by choosing the wrong part, leaving out a part, installing a part backwards, etc” It provides instant feedback and prevention of quality problems It is a tool that is  Mistake-proofing systems  Does not rely on operators catching mistakes  Inexpensive ‘Point of Origin inspection’  Quick feedback 100% of the time This tool can be applied to any process, be it in manufacturing or the service industry.

  31. 31. POKA- YOKE ERROR TYPES i. Processing Error: Process operation missed or not performed per the SOP. ii. Setup Error: Using the wrong tooling or setting machine adjustments incorrectly.iii. Missing Part: Not all parts included in the assembly, welding, or other processes.iv. Improper part/item: Wrong part used in the process.v. Operations Error: Carrying out an operation incorrectly; having the incorrect version of the specification.vi. Measurement Error: Errors in machine adjustment, test measurement or dimensions of a part coming in from a supplier.
