This case study describes implementing a quick changeover (QCO) process to reduce changeover times between production runs. The key steps are: (1) selecting a production team and target area, (2) documenting the current changeover process, (3) developing a future state process with separated internal and external changeover activities, and (4) implementing the new process. This standardizes changeovers and allows for smaller lot sizes and more frequent changeovers to produce products on demand. Benefits include reduced lead times and inventory levels. The case study provides examples of current and future state diagrams and a changeover matrix to plan production sequences.
