The installation of high rise shelving indicates an acceptance of wasteful inventory. This would just be added as a non-value step in their process. Lean philosophy leaves no room for surplus or safety stock. No safety stocks are allowed this philosophy says that, ‘If you cannot use it now, you do not need to produce it now.” Once production is done in excess, this can be considered as waste.

As we can see in the process, step 1 has one of the highest operation time and second to the highest when it comes to set up time. Therefore, adding a machine here will help improve the production of the...
