Understanding SMED Methodology Concepts

Dr. Beth Cudney introduces the concept of Single Minute Exchange of Dies (SMED), a technique aimed at reducing changeover times in operations to improve efficiency. Developed by Shigeo Shingo in the 1950s and 1960s, SMED is crucial in lean operations, allowing for more frequent product changes and reduced inventory. The video explains the difference between internal and external setups and emphasizes converting internal setups to external ones to minimize downtime. The stages of implementing SMED are outlined, including documenting current operations and streamlining processes.

What is the primary goal of SMED?

• To increase the production speed of machines

• To reduce the changeover time for operations

• To improve the quality of products

• To decrease the cost of raw materials

What does the term 'single minute' refer to in SMED?

• Five minutes or less

• Ten minutes or less

• Nine minutes or less

• One minute or less

Who developed the SMED methodology?

• Kiichiro Toyoda

• Shigeo Shingo

• Eiji Toyoda

• Taiichi Ohno

In which industries was SMED initially developed?

• Retail and Logistics

• Healthcare and Education

• Manufacturing and Machine Tool

• Automotive and Electronics

What is an internal setup in SMED?

• Operations that involve external tools

• Operations that require the machine to be off

• Operations that can be done while the machine is running

• Operations that are performed by external contractors

How can external setups help in reducing changeover times?

• By reducing the need for skilled labor

• By allowing setups to be done while the machine is running

• By increasing the machine's speed

• By improving the quality of the final product

What is the second main point of SMED?

• Improving the quality of raw materials

• Increasing the number of machines

• Converting internal setups to external setups

• Reducing the cost of production

What is the first step in documenting the SMED process?

• Streamlining the setup operations

• Separating internal and external setup times

• Creating a Pareto analysis

• Videotaping the current operations

What is the purpose of a setup analysis chart in SMED?

• To document and analyze the setup process

• To increase the speed of production

• To reduce the cost of materials

• To improve the quality of products

What does a Pareto analysis help identify in the SMED process?

• The cost of production

• The quality of raw materials

• The major categories where time is being spent

• The number of machines required
