In a lean production strategy, one of the key principles is to eliminate waste and increase efficiency. Implementing manufacturing cells is most appropriate as it creates a more streamlined and flexible approach to production, reduces movement and wait times, and increases efficiency. This method aligns directly with lean production principles. Increasing service through inventory and push strategies often lead to overproduction and excess inventory, which are considered waste in lean methodology. Batch type operations can also lead to inefficiencies and increased lead times. Therefore, implementing manufacturing cells is the most suitable activity for lean production.
