JIT (Just in Time) systems aim to eliminate waste by producing and delivering only what is needed when it is needed. This reduces excess inventory, waiting times, transportation, and other inefficiencies. JIT is well-suited for environments with highly repetitive and predictable workflows and material flows. It relies on pull systems, continuous improvement techniques, small lot sizes, uniform workloads, and consistently high quality to minimize waste and costs. While capacity increases can reduce lead times and inventory levels under JIT, achieving its benefits requires a flexible workforce and close supplier collaboration.
