Changeover time is the time that is required to do certain set-up change before starting a different set of operation. With SMED technique , we can reduce the waste in an efficient way by converting a manufacturing process for one product to next product. Steps involved in SMED are as follows 1. Calculate total time required to perform the task. 2. Identify Internal and external tasks. Identify the external task which can be performed parallelly when the equipment is running 3. Identify internal task which can be converted to external task. 4. Eliminate the internal waste 5. Eliminate the external waste 6. Standardize Example: In a car manufacturing company , dashboard assembly is a major activity that was initially done as a main process. Over the period of time, dashboard assembly was defined as an external activity. With this SMED Technique when the main assembly is in process, dashboard assembly was performed as a sub assembly, which reduces the car manufacturing time.
