Setup reduction achieved through the SMED approach (Single Minute Exchange of Die) There are advanced preparation of equipment needed for production allowing for a fast changeover from one operation to another. (This is the foundation to move from a batch mentaUty). 

Setups cost money and take time. If the setup takes too much money, then there will not be enough capacity at a work center to produce all the products required. When setups take too long at a work center, it is not possible to implement the pull system without reducing the setup time. This concept is sometimes called SMED or single-minute exchange of die. 

Also, as the cost — and here we mean incremental cost — of an individual order declines to zero, so does the economic order size. An example is the development of techniques to reduce costs of activities such as setup. SMED, or single minute exchange of dies, emphasizes fast setups. In applying SMED, analysts use videotapes and methods analysis to make sure machines are not offline too long when setups are needed. What SMED does is reduce the so-called economies of the batch model. 

This just-in-time approach generally precludes large batch production instead items are made in batches of one. This means that operators have to be flexible, the system has to be flexible and single minute exchange of dies (SMED) becomes the norm. A lean approach reduces the number of supervisors and quality inspectors. The operators are trained to know the production standards required and are authorized to take corrective action, in short they become their own inspectors/snpervisors. The principles of TPM (Total Productive Maintenance) and Five Ss (Sort, Set in place. Shine, Standardize and Sustain) are followed and as a result the equipment becomes more reliable and the operator develops ownership towards the equipment. 

Single minute exchange of die (SUED) Operator techniques pioneered by Shigeo Shingo, a Japanese industrial engineer, that result in changeovers of production machinery in less than 10 minutes.
