If we decrease the set-up times we could use the extra capacity either to increase productivity or to decrease the batch sizes. Typical benefits are:
So how could SMED be effectively implemented?
Based on my experience, the following steps are the key treads that would best guarantee the successful implementation:
Step 1 Focus. Start by choosing the right equipment to start with. This is normally a bottle-neck with long set-up times
Step 2 Build the right team. Work cross-functional. Operators, Technicians, Engineers and Managers should work together
Step 3 – Measure and set goals. Visualize the present situation and agree on a common goal
Step 4 – 5S. To succeed you will need a clean and well organized work-place. A 5S implementation is recommended
Step 5 - Analysis. Keenly observe the operations and processes. Analyze the present situation video-technique. The different moments are classified as being external or internal and waste or not waste. All known disturbances are listed as well.

Step 7 - Elimination of waste. Measures are carried out to reduce all types of waste. This includes:
Step 8 Follow up and improve. Make sure that your new level sets the new standard
