J.I.T. - Just In Time

1. J.I.T. - Just In Time

2. History • The basic elements of JIT were developed by Toyota in the 1950s. • This evolved into the Toyota Production System. • Adopted, as part of ‘Lean manufacturing’, by many process manufacturers

3. Supplier Stock Process What is JIT and why do we do it? • Aligned to plan • Continuity of supply critical • Quality control • Spread risk • Minimise level • Working capital • Cashflow • Space • Avoid obsolescence • Demand driven • Easy to plan • Continuous • Flexible • Part of Lean

4. This theory is applicable to repetitive manufacturing processes • Ensure that the right parts are in the right place at the right time • Minimise waste by reducing inventory (increasing inventory turnover) • Ensure the use of a stable plan (no late/ rush orders) • Ensure quick set up times on all production lines • This allows short production runs & small purchasing lot sizes • Use preventative maintenance plans (during non production time to avoid unexpected breakdowns) • Ensure that there is a well trained flexible workforce (to minimise line manning issues) • Implement a supplier quality assurance programme (to ensure there are no issues with raw materials) What is JIT and why do we do it?

5. Case Study – Edrington • Each order is exploded into its component parts • Production orders are raised and scheduled on the production plan • Raw material orders are raised by the Buyers/ Resource Planners • Raw material delivery schedules are agreed with the suppliers • Materials are stored close to their point of use • Production personnel request materials using a computerised Kanban system • A preventative maintenance system is used to maintain production lines • A vendor appraisal/ supplier award system is used to maintain quality/ cost/ service
