What is a SMED Template?
A Single-Minute Exchange of Die (SMED) template is a structured document or digital tool used to standardize the process of equipment setup and changeover in manufacturing. Developed by Japanese engineer Shigeo Shingo, The goal of this template is to help reduce setup times to less than ten minutes, hence the term “single-minute.” While manufacturing processes benefit greatly from SMED, other industries that have frequent changeovers are able to take advantage of the features of this approach.
Importance
A SMED template is crucial in Lean manufacturing because it standardizes and optimizes the equipment setup and changeover process, directly impacting productivity and efficiency. By providing a clear, step-by-step guide, the template helps operators perform setups more consistently, reducing variation and human error.
With a well-maintained SMED template, companies can achieve significantly shorter changeover times, allowing them to respond more flexibly to production demands, reduce inventory levels, and improve overall production flow. Additionally, the template supports continuous improvement by highlighting opportunities to refine tasks and eliminate unnecessary steps so that greater focus can be redirected to checking for quality and compliance.
Benefits
Using a SMED (Single-Minute Exchange of Die) template offers multiple benefits that enhance efficiency and flexibility in manufacturing operations. Here are some key advantages:
- Reduced Setup Time: By clearly outlining each step in the changeover process and identifying tasks that can be done while the machine is still running, a SMED template minimizes downtime, enabling faster transitions between production runs.
- Increased Production Capacity: Shorter setup times mean that machines spend less time idle and more time producing, allowing for higher output without the need for additional equipment or shifts.
- Lower Costs: Faster setups using a template reduce labor and machine costs associated with changeovers, while increased production capacity may decrease the need for additional capital investment.
- Employee Engagement: By involving operators in the SMED process and using a standardized template, employees can contribute to process improvements and develop a deeper understanding of setup efficiencies.
How to Use a SMED Template
It is important to properly know how to use a SMED template to maximize the benefits it presents. Here is a step-by-step guide to help you get started:
- Describe the circumstances surrounding the changeover. Mention the equipment used, the time equipment was running and stopped, and the production line involved.
- Go into further detail with the changeover elements present. Determine whether this changeover can be completed while the equipment is running.
- Indicate if there is an internal changeover element present and answer the relevant questions listed in the template.
- Be as specific as possible when describing suggestions on how to perform changeovers in less time to help with continuous improvement.
- Add the time required for internal changeover elements.
- Record the equipment changeover time after going through the SMED process.
- Update the template as often as necessary. Append additional sections to record any new observations and recommendations, if needed.

FAQs about SMED Template
A SMED template should be updated whenever there are changes that impact the setup process, as its accuracy is critical for efficient setup time reduction. Examples of this include:
- Process changes
- Introduction of new equipment or tools
- Compliance or safety updates
- Routine improvements
Quality managers are the primary point persons for updating a SMED template. They are responsible for ensuring that quality standards are followed throughout different operational processes. By overseeing the use of SMED templates, they can gain better understanding and visibility over potential risks and make sure everything is running smoothly.
Organizations may face several challenges when using a SMED template, which can hinder its effectiveness in reducing setup times. This can include the following:
- Resistance to change
- Lack of training or understanding of SMED processes
- Accuracy of data collection
- Process mapping for changeovers
As such, it is crucial to have proper management support to implement effective strategies to help with SMED and maximize the benefits presented by this process.
