Illustration of Individual Kaizen Theme: Improvement in bracket bellow support assembly for machine assembly Before Kaizen: There was a strain in mounting the Bracket bellow support on to slim3 machine. 2 persons required to assemble the cover After Kaizen: Fixture made by using simple frame from in-house parts. Single person can assemble the cover. Easy handling of part since crane will be used
  7. 7. WHY KAIZEN • Easy to understand • Easy to implement • All functions can participate • Does not involve much expenses • Does not need any major tool, Except ….. Motivation • No expensive training required to implement
  9. 9. CHANGE Stumbling blocks for change 1. I have done it before… it did not work 2. It is not my idea…. it will not work 3. Why change …..while I am comfortable 4. Nobody has ever tried…. so it will not work
  10. 10. KAIZEN – FOCUSED IMPROVEMENT Improvement Focused Improvement KAIZEN Paper does not burn in sunlight Paper burns Improvement is like sunlight: • Lot of energy, but dispersed (wasted) • Small improvements • Slow progress. Focused improvement concentrates the energy: • Little energy, but concentrated and aligned • Enables significant (large) improvements • Small time required • Rapid progress
  11. 11. TRADITIONAL ORGANIZATION Customer expectations Top Mgmt. Middle Mgmt. Gemba Customer satisfaction
  12. 12. ORGANIZATION FOR KAIZEN Customer expectations Gemba Organization to support Customer satisfaction
  13. 13. THE THREE GOALS OF OPERATIONS-QDC • Customer expectation is three fold: QDC – QUALITY – DELIVERY – COST Customer is satisfied QUALITY-Better firm customer • The Firm’s response should be: BFC – BETTER – FASTER – CHEAPER Firm develops competitive advantage! DELIVERY Faster - COSTCheaper
  14. 14. • QDC DEFINITIONS & QUALITY CONCEPTS – – – – It is “conformance to customers requirements” Its target is “zero defect” Its measure is “cost of nonconformance” Its system is “prevention” • DELIVERY – – – – Meeting the promised time Delivering by expected time Crashing leadtimes & cycletimes Meeting schedules • COST – Value derived by customer – Driver of Competitive advantage – Nonvalue adding activities(NVA)-Waste

  32. 32. Criteria for the Kaizen committee • Originality of idea • Multiple Area of ideas • Business Impact of the idea • Innovation involved • Implemented & benefits realised • Low investment
  33. 33. GENERAL RULES OF KAIZEN • Do it Today • Do not take NO for an answer • Do not find out why it cannot or should not be done. Do it. • Do not wait for perfection; 60% is good enough. Move!
  34. 34. KAIZEN and NEW VENTURES 1. The journey of Kaizen cannot ignore any of the QDC parametersyet any one of them is always more critical than the other two depending upon the business context at a given point in time During the startup of new ventures, 2. • • • 3. high emphasis should be given to innovation and quality assurance, and once high level of confidence was built on product reliability, thereafter the management priority shift to shorter lead-times and promised dates, and once that was settled finally cost efficiencies and business profitability become important. The top management keep an eye on the earlier objectives so that it is not diluted during the process of shifting Kaizen focus subsequently from Q to D and later from D to C.
  35. 35. In conclusion…. • CUSTOMER SATISFACTION – QUALITY, DELIVERY, COST • COMPETITIVE ADVANTAGE – FASTER, BETTER, CHEAPER – OVER PAST, OVER OTHERS • CONTINUAL IMPROVEMENT – MURA, MURI,MUDA – STRAIN, DISCREPANCY, WASTAGE • Close correlation with worldclass practices in manufacturing and success of business
  37. 37. Actual Examples
  38. 38. CONTINUAL IMPROVEMENT Before Kaizen: No coolant filtration unit for ID grinding machine After Kaizen: Coolant filtration unit created using existing tank. Chip filtration ensured
  39. 39. CONTINUAL IMPROVEMENT Before Kaizen: No support for casting. Hence was being placed on critical machined surface After Kaizen: Small supporting fixture provided. Avoids any damage to machined surface. Also safe method of placing component
  40. 40. CONTINUAL IMPROVEMENT Before Kaizen: There was no method other than CMM to check the final size of Ø 58 F8.Separate inspection time was required and machine was kept idle to check this diameter in CMM. Ø 58 F8 After Kaizen: Special Gauge is made to check the size,QC inspection is not required before I/D grinding.
  41. 41. CONTINUAL IMPROVEMENT Theme: Improvement in bracket bellow support assembly for slim3 assembly Before Kaizen: There was a strain in mounting the Bracket bellow support on to slim3 machine. 2 persons required to assemble the cover After Kaizen: Fixture made by using simple frame from in-house parts. Single person can assemble the cover. Easy handling of part since crane will be used
  42. 42. QUALITY IMPROVEMENTS Theme: Process improvement for 21M120A717 (Bearing screw) Before Kaizen: Concentricity between OD & ID was achieved about 50 microns against required 30 microns This was due to the holding of work piece with 3 jaw chuck After Kaizen: Process changed by completing the OD grinding, assembling part on to mating component and ID grinding after the assembly This ensures that both OD & ID are concentric (within 10 microns) and no distortion of parts
  43. 43. QUALITY IMPROVEMENTS Theme: Storage of spindle shafts for Slim3 Before Kaizen: The storage of spindle shafts was being done with the help of a wooden V block fixture. This method was prone to damages After Kaizen: Special trolley introduced for storage of spindle shafts. Easy handling of spindle shafts. No damages will be caused during transport
  44. 44. CONTINUAL IMPROVEMENT Theme: Dummy probe pocket for CMM Before Kaizen: CMM probe was kept on a surface table. Due to this being a regular working area there were chances of probe getting damaged . The probe is very expensive and costs. After Kaizen: Probe damage avoided completely. House keeping also improved on CMM surface table
  45. 45. CONTINUAL IMPROVEMENT Before Kaizen: There was no fixture for proximity tightening. After Kaizen: Two holes made on the table so that proximity can be fixed while tightening the connectors
