The document discusses moving the NHS supply chain from a push to a pull model. Currently, the NHS uses a push supply chain where equipment and supplies are ordered based on forecasts of estimated demand. However, demand is difficult to accurately predict and this model has led to failures like shortages during unexpected increases in demand or waste of expired supplies when too much is ordered. The document proposes transitioning to a pull supply chain where suppliers automatically replenish stock based on actual customer orders rather than forecasts. This could help the NHS supply chain better match supply to variable demand and improve efficiency.
