  1. Unlocking the Potential in the Supply Chain through Lean Logistics David Taylor Cardiff University 2004 Queensland Supply Chain Seminar Brisbane 10 & 11 June

  2. Agenda • Yesterday : The Background & Theory • Lean Thinking v Mass Production • Understanding Waste • The Lean Principles • Today : The Practice • Lean Tools & Techniques • Case Studies of Lean Applications & Benefits

  3. Overproduction Defects Waiting MUDA Non-Value-Adding Activity Unnecessary motion Transport inventory Inappropriate Processing What have we Got So Far ? Mass Production Thinking V Lean Thinking The Five Lean Principles • Specify value • Identify the value stream • Make the product flow • So the customer can pull • Manage towards perfection The Seven Wastes

  4. Value Stream Management The application of Lean Thinkingto improving business processes Lean Mapping ToolsLean Improvement Tools Lean Strategic Techniques

  5. Total Value Stream Action Action Action Action Action Action Multi-plant Plant Action Value Streams VSM Can Be Applied at All Levels

  6. Value Stream Management A Dis-Aggregated Approach It deals with individual value streams separately

  7. Dis-Aggregation By Product Family Product Group A Product Group B Customer Product Group C Treat each product group as a separate Value Stream

  8. Value StreamManagement Methodology • Select a key value stream for pilot lean improvement - Key Product to Key Customer • Situational Analysis - Using ‘Mapping Tools’ • Develop model lean value stream – Using Lean Improvement Tools • Roll out lean to other value streams

  9. Value Stream Mapping ToolsLean Tools For Analysing the Current Situation & Identifying Waste • Process Activity Mapping • Current State Mapping • Demand Amplification Map • Quality Filter Map • Physical Structure map • Production Variety Funnel • Decision Point Analysis Create a Quantified Assessment of Process Performance

  10. Process Activity Mapping • The starting point for value stream improvement • Go to the work place and record what actual happens • Don’t do it in the office where you record what you think is happening

  11. Process Activity Map Summary Statistics Time Operations = 2 mins Inspection = 1 min Transport = 41 min Delay = 720 min Storage = 960 min Value Adding Operations Represent < 1% of Total time

  12. Huck Fasteners : Birmingham • Lean Improvement initiative • Mapped a pilot value stream - Hucktainer • Recorded & measured every step in making a specific product • Produced photo sequence – as part of their internal lean education process

  13. Huck Fasteners Performance Improvements from Lean • On-time delivery +10% • 40% Increase in V.A. per employee • 35% reduction in lead-times • 20% reduction in inventory • 40% of floor spaced freed - Cancelled £10m new factory • 55% reduction in set-ups Morethan offset 5% loss in margin due to foreign competition

  14. Current State Mapping • A Toyota tool • A clear visual representation of a process • Links Physical Product Flow Information Flow Time • The first tool to do this !

  30. Value Chain Analysis : Benefits • A joint value chain mapping team – a practical way to develop real cooperation & a joint vision • The whole team goes & sees all the operations and gets a real understanding of each other’s issues • Each firm identifies internal improvement opportunities • Opportunities are identified that are only available when firms cooperate

  31. Corus – Metsec – Gateway Steel coils Sections Caravan Chassis Benefits from Supply Chain Cooperation • Stock reduction across the Chain - 50% • On-time Delivery Improvement < 90% to 98% • Quoted Order to delivery lead time 21 days to 3 days • Increased Mutual Business + 40%

  36. Lean Applied in The Public Sector Local Government The BBC Hospitals

  37. Medway Hospital: Emergency Medical GP Referral Decision Flow Duplication of paper & computer systems Decisions=Major Source of Delay to patient progress Info Doesn’t Flow No standard system to ensure decisions Flow Major Cause of delay to patient flow Complex & time consuming Decision making often ad-hoc Lot of decision points( 17) & Many People involved Evolved Not planned Non systematic 8 process steps & 9 queues Information Flow 6-8 hrs from GP to bed Patient Flow & time Mapping by Walking the process With a pencil, paper & rubber 5- 8 days in-patient 1-5 hours to discharge

  38. Lean Future State Vision Current State Number of steps 24 Number of value steps 24 Time 4 -6 hrs in hospital 10 hrs input at home Number of steps 67 Number of value steps 27 Time 10 days in hospital Medway : Lean Thinking Pilot

  39. Medway : Value Stream Mapping • For the first time people start to see & understand the whole process of a patient coming into, through & out of hospital • Started ‘patient-centred’ process thinking • Identified wastes & inconsistencies • Led to immediate waste removal

  44. Conclusions : So why Lean? • Lean shifts the focus from managing assets to managing end to end processes • It reveals opportunities by distinguishing what creates value from what does not • It gives people the tools to redesign their processes to cut unnecessary steps and time • And it builds a social basis for collaboration between partners to achieve and sustain improvement

  45. What is Lean aiming for :- For Businesses Gaining Competitive Advantage And More Business At More Profitable Levels For Non-Profit Organisations Improving Efficiency Better Service
