Estimate the manufacturing lead time for processing the product (recall that lead time is defined as the moment raw materials enter the facility to the moment that the finished product leaves the facility for delivery to the customer). III. Identify each conversion/transformation operation in the process and the time taken in each operation to transform one unit (or batch of units). Transformation operations (value-adding) time 1. 2. 3. 4. 5. 6. 7. 8. Total time for value-adding operations IV. Calculation of value-adding ratio (percent): Total time for value-adding operations/total mfg. lead time x 100 = _____ % (Value-adding ratio)

- Achieving Quick Changeover Participant Manual © 2007 Productivity, Inc. AQC0100PM_0907 Many people take for granted that changeovers will always take a long time. This does not have to be the case. The organization, if it is to successfully reduce changeover times, must challenge the following traditional assumptions about changeovers. In the past we believed that: Determining an Economic Order Quantity would balance the increased cost of large inventory caused by large-lot production with the reduced costs associated with long runs. The break-even point would be calculated. Large-lot production is inherent in some types of processes, such as chemical reactions or consumer products. Fewer setups lead to increased efficiency and production capacity. A high level of knowledge and skill is required for effective and efficient changeovers. This is only acquired through lots of practice and long-term experience. These ideas, once believed to form the basis for rational production policies, are flawed. They are based on the assumption that changeover or setup times cannot be reduced. Changeover times are not a constant, especially when you consider the variation in performance.
