4 LEAN Kaizen, Maasaki Imai Lean Toyota Production System, Taiichi Ohno

5 KAIZEN KAI = Change ZEN = Good (for the better) KAIZEN = Continuous Improvement

6 What is Lean? Lean is a continuous improvement process of eliminating waste to reduce the actual time between when a customer expresses a need and when that need is satisfied.

7 Why LEAN costs + margin = sales price sales price costs = margin

8 Why LEAN forecast accuracy Forecast accuracy as function of time 100% 80% 60% 40% 20% 1 # days before shipment 0% order parts receive parts manuf. assembly shipment PWC Delivery Perf. supplier High C/O time Low O.E.E Process availability Assembly errors Rejects End-test

9 Why LEAN

10 CASH is King Business, cost of sales 130,000,000 Throughput time is 4 weeks Material turn = Inventory = 13 10,000,000 Throughput time is 2 weeks Material turn = Inventory = 26 5,000,000

11 INVENTORY (EXCESSIVE) MUDA of Inventory WHEN THE INVENTORY IS FULL... WATER SURFACE ABNORMAL OPERATION AFTER THE UNNECESSARY INVENTORY HAS BEEN REMOVED... GENERATION OF DEFECTIVE PRODUCTS DELAY IN DELIVERY UNSEEN OBSTACLES AND DEFECTS IMBALANCE IN WORKFORCE PERFORMANCE PROBLEMS BECOME APPARENT BREAKDOWN OF PRODUCTION FACILITY

12 Learning to See Added Value & Waste

13 Definition of Value Added From the Customer s perspective, every activity process that involved in creating the product or service can be considered as Value-Added or Non Value-Added Value-Added Activities Transforms material or information Done correctly the first time What the Customer wants What the Customer is willing to pay for Non Value-Added Activities (but necessary) Activities causing no value to be created but which cannot be eliminated Required activities by regulatory agencies Necessary due to risk reduction Non Value-Added Activities Activities that consume resources (time or space) but create no value in the customers eyes

14 What is Waste? Anything other than the minimum amount of equipment, materials, parts, space, and time, which are absolutely essential to add value to the product or information. If it doesn t add value - - it s waste.

15 Waste - Non-Value Adding Activities The goal is to do only Value Adding activities VA VA The opportunity is to eliminate as much of the Non Value Adding activities NVA NVA

21 LEAN Continuous improvement Elimination of waste Focus on process speed, reduce time Involve everyone Tools, Methodology, Philosophy

22 Six Sigma

23 What is Six Sigma? Six Sigma can be defined and understood at three distinct levels: Metric : 3,4 Defects Per Million Opportunities Methodology : DMAIC DFSS structured problem solving roadmap and tools Philosophy : Reduce variation in the business and make customerfocused, data driven decisions

24

25 What is σ? σ is a measure of how much variation exists in a process x x X avg x σ = SQRT [SUM(X-Xavg) 2 / (n-1)]

26

27 Six Sigma as a Metric Sigma = = Deviation ( Square root of variance ) Axis graduated in Sigma between + / - 1 between + / - 2 between + / - 3 between + / - 4 between + / - 5 between + / % % % % % %

28 Variation LSL USL LSL USL Off-Target, Low Variation High Potential Defects Good Cp but Bad Cpk On Target, High Variation High Potential Defects Not so good Cp and Cpk LSL USL On-Target, Low Variation Low Potential Defects Good Cp and Cpk Variation reduction and process centering create processes with less potential for defects. The concept of defect reduction applies to ALL processes (not just manufacturing)

29 Six Sigma as a Metric Process Capability PPM 308,537 66,811 6, Defects per Million Opportunities

30 How good is good enough? 99.9% is already VERY GOOD But what could happen at a quality level of 99.9% (i.e., 1000 ppm), in our everyday lives (about 4.6 )? 4000 wrong medical prescriptions each year More than 3000 newborns accidentally falling from the hands of nurses or doctors each year Two long or short landings at American airports each day 400 letters per hour which never arrive at their destination Is this good enough.?

31 What is Six Sigma? Six Sigma can be defined and understood at three distinct levels: Metric : 3,4 Defects Per Million Opportunities Methodology : DMAIC DFSS structured problem solving roadmap and tools Philosophy : Reduce variation in the business and make customerfocused, data driven decisions

32 What is Six Sigma? Pro Active DFSS Design for Six Sigma Re- Active DMAIC Define Measure Analyze Improve Control

33 DMAIC Define : Clearly defined problem, goals and metrics Measure : Accurate, reliable, consistent DATA used to make decisions. The baseline is captured, so improvement can be measured Analyze : Data analyzed to truly identify causes/barriers Improve : Develop actions to solve the problem, then prove it Control : Ensure sustained performance

34 DFSS Methodology & Tools DESIGN FOR SIX SIGMA Initiate, scope, and plan the project Understand customer needs and specify CTQs Develop design concepts and highlevel design Develop detailed design and control/test plan Test design and implement full-scale processes Define Measure Analyze Design Verify DELIVERABLES Team Charter CTQs High-level Design Detailed Design Pilot TOOLS Mgmt Leadership Customer Research FMEA/Errorproofing Project QFD Process Simulation Management Benchmarking Design Scorecards

42 The LEAN & Six Sigma Structure

43 LEAN A philosophy of the possibility and desirability of constant change for the better A management system that supports continuous improvement through adherence to the PDCA improvement cycle The application of operating principles to constantly expose and eliminate waste in the process of delivering value to the customer A way of working that relies upon everyone continuously seeking to improve how they carry out their job

44 Elements of the LEAD Structure LEAD Organization Business Organization & Management of LEAD LEAD Management Alignment with key business goals Quality Flow Measurements LEAD Improvement Tools LEAD Leadership and Culture Leadership People Involvement Change culture

46 Role of HR in LEAN Six Sigma

47 HR role in LEAN Apply lean practices and principles toward process improvement in HR processes. Actively support (LEAD?) lean transformation throughout the company.

48 LEAN Six Sigma in HR processes

49 Lean in HR processen Wat zijn de primaire HR processen? Hoe bepaal je die? Wie is je klant? Hoe tevreden is die klant? Kijk je naar die processen vanuit de positie van die klant? Wie is je leverancier? Hoe tevreden ben je over de aan levering van informatie? Meet je de kwaliteit van de HR processen? Wat is in die processen de verhouding tussen doorlooptijd en tijd waarbij je waarde toevoegt?

50 Lean in HR processen Invullen van een vacature, kosten, snelheid, kwaliteit Verlaging van het verloop Verlaging ziekteverzuim Benodigde tijd voor slarisverwerking Aantal fouten per maand in salarisverwerking Aantal rapporten en documenten dat geproduceerd wordt - Is het duidelijk waarom je een rapport maakt, (5 Why) - Kan het sneller / korter / beter (VOC) Hoeveel tijd ben je kwijt doordat de input fout / onvolledig is Snelheid van de jaarlijkse beoordelings / salarisronde Aanwezigheids registratie

51 Makigami / Process Mapping? Makigami literally means Roll of Paper in Japanese Makigami Process Mapping is a pencil and paper tool used to analyze and visualize any business process Makigami is specifically suited for environments where products are not visible or physical [Office Environment] Makigami allows for simple tracking of system processes, Touch Time, Wait Time and information transfers Makigami helps identify non value added time within the process Makigami Creates Standards for all processes
