In this presentation we will discuss the following
questions and learn how to use SMED for continuous
improvement. Through a “Kaizen Event”-(Change for the
Better) we will improve.

SMED
What is SMED? Single Minute Exchange of Dies
 SMED (Changeover Reduction) is a tool supporting
Lean Manufacturing. It is used to control and
decrease downtime due to changeovers.
 SMED supports the concept of continuous
improvement through the removal of waste.
 SMED will make the job more structured,
repeatable and easier.
 SMED will take care of our Customers better
than we do today.

SMED
What is SMED? Single Minute Exchange of Dies
 SMED is about increasing productivity by
decreasing the time from the last good
“Set-up Reduction”
product to the first good product.

Why is SMED important?
The Customer
 Reducing set-up time helps us to better serve our
customer needs.





5
Decreases lead time
 Smaller batch sizes
Increases flexibility
 Growth opportunities
Increases “Customer On Time” delivery
 Get product when they want it
Supports Takt Time-(Time a product takes to meet a demand-cycle
time)
 Run to Customer demand not standard
Allows us to keep all Customers happy
5
 Each Customer gets what they want
SMED
Why is SMED important?
Cycle Time
 Better able to provide all customers with what
they want quicker & decrease inventory.

SMED
Why is SMED important?
 Think how would you handle your own
household.
 Would you buy a weeks worth of groceries or
a months worth at a time. Why?
1. Money-Cash Flow
2. Space-Inventory
3. Don’t need so much-Buy when needed
4. Perishable-Obsolete

SMED
Why is SMED important?
 Line down time is costly. We need shorter
changeover time.
 We are losing money when the line is down.

SMED
Why is SMED important?
 Improper set-ups can have negative effects on
equipment reliability, safety and quality.

SMED supports TPM (“Total Productive Maintenance”)
Uses Mistake Proofing or (“Poka Yoke”)
Reduces injuries due to machine failure
Establishes Standard Work for all operators
Assists with new operator training

Why is SMED important?
 Controlling line down time
allows for better planning and
supports a “Just In Time”
strategy.

SMED
Where should SMED be used?
 SMED should be used on a
machine or process which
requires a complicated or time
consuming set-up. (On the average
86% of a process is waste.)
NASCAR example: You VS Pit Crew
Changing 4 Tires (1 Hour VS 15 Seconds)
 SMED is supported strongly by
TPM, 6S and SW. It should be
used in an area to support Visual
Management practices.
 SMED reinforces other Lean
Manufacturing tools and should
be used as part of an on-going
move toward continuous
improvement.

SMED
How do we use SMED?
 SMED, as a Lean tool, can be used during a Rapid
Improvement Event, Just Do It, or Project.
 Preparation for a SMED event should include:

Gathering data to support the current state.
 Video Recording
 Current records

How do we use SMED?

16
Videotape the area and then review the video
recording with the team and document the “Current
State.”-Initial Set-Up Time
 Capture the steps used in the
changeover.
 Document waste as it is
observed.
 Stay focused on the current
state. (Fence Posts)
 Try not to jump ahead to
improvement ideas.
 If the video is unclear, visit the area (“Gemba-Work
Place”) to gain a better understanding of the steps
involved.
16
SMED
How do we use SMED?
 Use the video to perform time
observations.






List each step as you observe the
video.
Capture the time for each step & the
total time.
Capture walk & waiting times
separately (This will help with later
steps).
Observe waste in the process and
make notes.
Total time from each step should
equal the total time of the
changeover.
List each step on large easel paper.
Have three columns to the right for
Takt time, Total time and Pro Forma of
each step.

 Separate Internal from External activities. Move
Internal to External.

Internal- What has to be done when the machine is down.

External- What can be done while the machine is still running.
 Eliminate adjustments- “Poka Yoke”-Error Proofing
 Kaizen- (“Change for the Better”) Internal activities and
6S External activities.
 Eliminate Set-Up. (Tools, blocks, gauges, markings)

Brainstorming Ideas
 Look at the waste you
8000
observed in the video and
brainstorm ideas to remove it.
 Write ideas into action items
on colored post-its.
 Target the largest time blocks
on the Current State Bar
Chart.

Wasteful Activity
 Look for the 8 wastes in the process?

Defects- Creating WIP (Work in Progress) or waste

Overproduction- Too much, too early
Waiting Time- Waiting for something before
continuing
Non-Utilized Talent- Damage to people
Transportation- Moving people or materials
Inventory- Accumulation of product to be worked
Motion- Unnecessary human movement (Turning,
twisting, bending, taking steps, etc…)
Extra Processing- Non value added to the

Set-Up Reduction Ideas
6S
 Develop checklists for all items necessary for
changeover

Tools, gauges, materials, parallel operators, etc.
 Perform checks on all items to insure proper function
and fit

Tools sharpened, rebuilt or preset
 Stage all items at the workplace
 Die carts, tool boards
 Think like the Operating Room
 Try to stay within a few feet of the process at all times
 Prepare operating conditions prior to changeover
 Flush ready, next product ready

How do we sustain SMED?
 Make a Key Points Sheet for the SW-
(Standard Work) Board.

This will be used to help train operators with
the new process.
 Make a Changeover Visual Control to be
used at the SW Board.

This will be used to track changeovers and
assist in sustainment.

Where do we go from here?
 Sustainment! Sustainment! Sustainment!

What can we do to help with sustainment?
 Talk with other people to let them know about the
benefits of a more organized facility.
 Encourage change for the better (“Kaizen”) and assist
with new ideas.
 Follow up on your event and raise attention when
sustainment has slipped. (“Audits”)
 Everyone must follow the key point sheet.
 We must collect data that is needed.
 Everyone must be on board!

 Continuous Improvement Never Stops!!!
