4.2.2—Just in Time (JIT)

Just in Time aims to receive inputs shortly before they are needed and produce to demand. It can reduce storage and tied-up finance but depends on reliable suppliers, quality and accurate scheduling.

JIT exposes problems that buffer stock would hide. A disruption, defect or demand surprise can therefore stop the process quickly.

A manufacturer may use small, frequent deliveries with trusted suppliers; a port delay can halt production if no contingency exists.

JIT is not simply “hold no stock”, and it is unsuitable when lead times or supply reliability make continuity more important.
