  1. Just in Time Neil Towers

  2. Definition of Just in Time Wherever possible no activity should take place in a system until there is a need for it. The system is driven by downstream requirements (Christopher, 1998)

  3. The meaning of just-in-time Traditional approach JIT approach Focus on Focus on high More producing capacity stoppages only when utilisation because of needed Fewer problems stoppages More production High inventory Lower capacity Low inventory at each reduces the utilization, but so problems stage chance of the are exposed problems being and solved exposed and solved Extra production goes No surplus into inventory because production goes of continuing stoppages into inventory at earlier stages

  4. JIT systems • Elimination of of Inventory in Supply Chains • Synchronised activity • Uninterrupted flow • Elimination of waste • Continuous Process Improvement

  5. The JIT philosophy JIT as a philosophy • Involve everyone • Continuous • Eliminate waste improvement

  6. Techniques commonly associated with JIT JIT as a philosophy • Involve everyone • Continuous • Eliminate waste improvement JIT as a set of techniques for managing operations • Basic working practices • Design for manufacture • Operational focus • Small simple machines • Layout and flow • TPM • Set-up reduction • Total people involvement • Visibility • JIT supply

  7. JIT planning and control JIT as a philosophy • Involve everyone • Continuous • Eliminate waste improvement JIT as a set of techniques for managing operations • Basic working practices JIT as a method of • Design for manufacture • Operational focus planning and control • Small simple machines • Pull scheduling • Layout and flow • Kanban control • TPM • Levelled scheduling • Set-up reduction • Mixed modelling • Total people involvement • Synchronization • Visibility • JIT supply

  8. Elimination of Inventory • More frequent deliveries • Small order quantities • Responding to immediate demand

  9. Uninterrupted flow • Flexibility of Supply • Visual control • Reliable and repeatable schedule • Increased flow through the pipeline

  10. Elimination of waste • Focus on value added • Dispense with non added value • Over production and waiting • Challenge all operating processes

  11. Continuous Process Improvement • Total people involvement • Culture and working practices • Flexibility and Creativity • Empowerment to workforce

  12. JIT philosophy • Driven by the demands of the consumer • Constant challenge to improve • Same day delivery
