SMED California stands for Single Minute Exchange of Dies. It is a tool in Lean used to reduce the amount of time it takes to change from running one process in an operation to running another. SMED can help reduce costs and increase flexibility within a process.
Depending on the process, setup within minutes may be very difficult, but in most cases, if the SMED principles are followed, drastic reductions in setup time can be obtained.
Principles of SMED California
SMED can apply to any process that requires a changeover, from creating software to the restaurant. SMED steps take place within one of two areas: Internal steps happen while the equipment or process is stopped and External steps occur while the equipment or process is running.
– Identify internal versus external changeover tasks
– Analyze each task’s real purpose and function.
– Focus on no/low cost solutions.
– Aim to eliminate changeover time.
SMED California is typically broken down into three stages. Each stage has specific tasks and objectives and all are inter-related and work together.SMED California can be implemented using below steps:
– Separate internal and external setup
– Convert internal setup to external setup
– Streamline internal and external elements
