OEE in the Lean News
I saw a post from Michel Baudin, Is OEE a Useful Key Performance Indicator? I don’t think it is. A few years back I wrote a blog about OEE and how it is very unclear as to what is really happening in a facility. It violates nearly every rule as to what is a clear and relevant metric.
Michel’s post started out with a bit from Jeffrey Liker’s post about OEE. This is the piece I found interesting from Jeffrey Liker:
Ignacio S. Gatell questions whether companies using OEE really understand it, can explain it clearly to their customers, and understand what it means to compare OEE as a KPI across plants. He questions whether even plant managers understand how it is calculated and what it means.
The only good argument for OEE is that at a macro-level in a plant it provides a high level picture of how your equipment is functioning.
I have to agree with Liker’s statement. OEE is good for a macro level idea of what is happening but you can’t understand what is happening without splitting it up into the components. Seems like Michel Baudin is thinking the same thing.
It is an overly aggregated and commonly gamed metric that you can only use by breaking it down into its constituent factors; you might as well bypass this step and go straight to the factors.
This is one of those blogs that gives me some of my sanity back. OEE seems to be so entrenched in “good business practices” it is hard to get people to move away from it. I get a lot of looks like I am completely crazy when I bring up my point of view. Thanks, Jeffrey and Michel. I see I’m not the only one now.

Model the Advantages of Using an A3
The A3 is a great communication tool. It can help tell a story succinctly and clearly making it easier for people to understand your thought process. An A3 will contain some background information, the current state, what the desired or future state is and an action plan to get there or measurements showing the success of the work.
Putting together an A3 can take some time. It isn’t actually putting the A3 together as much as it is truly understanding the issue and stating it clearly and concisely.
When your manager doesn’t understand the time it takes to truly understand how to put together an A3 it can be frustrating. As a lean learner, I encourage you to fight through that frustration and use the A3 to communicate with your manager or other managers. Show them the power of tell a good story on an A3.
The A3 won’t be perfect, but this is OK. If the others you are sharing it with understand your thinking then they can better add input. This better input leads to quicker high agreement and quicker resolution.
Think of using an A3 correctly as taking your time to do something right the first time, like setting up a machine. It may seem like it takes a long time but done right there isn’t as much rework because everyone understands quickly and you don’t have to have conversations over again because of the lack of understanding. Just like the machine being set up right the first time and not having to make tweaks over and over. In the long run, it is shorter to take your time upfront.
Eventually, others will see the benefits and the effects will spread.
Lean Concepts are Intertwined
When working with an area, department or organization to implement lean people like to focus on implementing a specific tool or concept, but it’s not that easy. The concepts and tools are so intertwined that focusing on one is really difficult to do.
An example would be implementing SMED (or quick changeover) across a facility. A vast majority of the time a large opportunity for improvement is through organization, having the tools you need where you need them and knowing when and where to be for the changeover. Immediately, other concepts that come to mind are visual management to understand when and where to be without having to ask. Also, 5S which can help with organization and having the right tools at the right spot. 5S is also a component of visual management.
A second example is implementing strategy deployment. There is standard work to how to cascade catchball down through the organization and it should be documented to be repeatable. Then the strategy is usually documented on an A3 to help communicate the message and most companies use visual management to show progress to the entire organization as time progresses.
As a person working to help others implement lean, it is OK to let them believe they are only focusing on one concept to start. Sometimes thinking about the intertwined concepts can become overwhelming. Let the customer focus on the one concept and introduce the other concepts through the backdoor. There is no need to call out the lean concept. Just discuss what a way to help them solve their problem in further implementing the concept the are focusing on.
At a later date, you can show them how they have actually implemented other lean concepts successfully. This helps build their confidence, shows further progress then what they believed and builds momentum to continue moving forward and taking more on.
Don’t get hung up on explaining all the intertwined concepts. Delivery on the needs of the customer and it will all work out.
What is 5S?
5S is a process to achieve a safe, efficient and organized workplace. It allows people to see if things are abnormal quickly, so they can address the issue. It does not keep people from doing something. 5S just allows someone to see if something isn’t right quickly.
The Five S’s are:
- Sort – Decide what is needed and what is not needed. Get rid of the things not needed.
- Straighten – Understand how things are used and put them in an appropriate place for the work space.
- Shine – Clean and label the area.
- Standardize – The work you have done is the new standard and needs to be kept that way.
- Sustain – The hardest part is not to let the work space degrade. Put checks in place to keep the standards in place.
Quite often 5S is equated with being lean. A large number of people believe that 5S is foundational to being lean. The thought is 5S is the first thing an organization must do to be lean. That is not necessarily the case.
Something as simple as organizing the workplace can help improve the efficiency of many things you do. I have seen 5S help gain large improvements with quick changeovers of machines. Looking for tools always seems to be the biggest waste when breaking down a setup of a machine, so having the tools in a particular spot every time can help a lot.
5S is not just for the manufacturing floor. It can benefit any work space, including in the office. But you do have to be careful. When it comes to 5S in the office many people get carried away. They prescribe marking where the computer should be and taping an outline around the stapler at everyone’s desk. This isn’t the purpose of 5S, so be sure to do 5S correctly in the office in environment.
Think of a NASCAR garage when doing 5S. It is spotless. The reason, so any drip from the car can be seen immediately and the problem can be addressed. You can’t go too far with organizing your work place.
5S is hard work. The hardest part is sustaining the work of the first 4S’s. Sustaining the work takes discipline. If the discipline is maintained the rewards of 5S can be great.
Good luck on your path to success with 5S.
Use the Right Visual
Visual management and visualization is a concept that lean relies heavily on. There are a lot of standard visuals like metric boards, kanban signals, 5S and value stream maps.
Visuals really help people understand the information. Everyone sees the same visual and it starts a good conversation allowing people to gain high agreement. The issue is all the visuals I listed are tools and as with any tool you need to understand when to use it.
To be effective with using visuals, you need to understand what information the group is trying to understand. What is the purpose of the visual? Who is the audience? What do they need to learn from it?
Most of the time the standard visuals will be perfect. You can use them and get everything you need. That is why those tools are well known, because they are used all the time and work. But sometimes, they won’t.
Don’t be afraid to make up a visual tool to present the right information in an easily digestible manner.
Here are a couple a colleague and I came up with for a recent event:
This one shows the % of time people spent doing different tasks throughout the day. It helped the group better understand who was doing what and for how long.
This one shows the frequency of tasks. Daily, Weekly or Monthly? What was the task done on? Who many times on that day?
In both cases, the different colored post-its represent different areas of the company doing the work.
As you can see, the standard visual tools would not have shown this information in a easy manner to understand. We designed this for the group and it worked very well.
We can’t always rely on the tools we have and know in our toolbox. Sometimes we have to think outside the toolbox. It is important to understand what your customer/group is trying to accomplish and design the visual accordingly. Don’t meet the needs of the tool. Meet your group’s needs.
Owning a Small Business is Very Educational
If you are a regular reader of Beyond Lean, you may know that my wife has her own small business. It is just her and I. She runs the business 24/7 and I help where I can on nights and weekends.
Both of us have learned about a wide range of business aspects over the last couple of years from her small business. My wife has a background in marketing, but has learned a lot about IT and web design, materials, costing, production of a consistent product, using data to determine what the customers like and a lot more.
I have been working quite a bit with display booth setup and teardown (quick changeovers), preparing raw materials for usage and investment decisions.
When owning and running a small business a person can see everything from end-to-end. How a packaging decision can affect sales? How does shelf life of a product have an effect on the quality? How do certain ingredients react when mixing for production? Do they cause immediate quality issues? Do they cause quality issues over time?
In our experience, we have seen how lean thinking can be more natural for a small business. There is more of a concern about inventory and cash on hand, so there are many decisions that go into building to stock or building to order. Using visual management to make things easier to see when work needs to be done or not. I have some examples from my wife’s business that I will post at a later date as well as examples I have posted in the past.
I have learned numerous things from working with my wife in her small business that I carry on to my other job as lessons to apply.
Owning a small business is very hard work. You have to learn about things that don’t necessarily interest you, but if you want to be successful you have to get it done. In the end, it can be very rewarding and extremely educational.
The Answer is Easy…Better Forecasting
Have you ever sat in a meeting where the discussion is about the high (sometimes low) inventory levels? Do you frequently hear the answer of, “Once we get our better forecasting tool in place our inventories will be better.”?
This is a strong sign the company has not fully embraced lean thinking.
A lean company would not even have a discussion where forecasting tools are the solution. A lean company is closely connected to their customers. The goal is to make one product when one product is bought by the customer. I know this isn’t easy for all companies, but the discussion would be around how to move in this direction. Not how a better forecast can be generated.
There is one thing I can guarantee about a forecast. It is WRONG!
I have never heard anyone say, “Man, I nailed that forecast! I hit it right on the nose!”
Don’t misunderstand me. I do believe there is a use in looking forward and understand what is coming. A company would like to understand if a peak or a valley of the product sales might be coming. This can help set and adjust maximum kanban levels for that period of time.
A forecast is good to understand directionally where volumes are heading. Forecasting is not a good basis for your entire inventory strategy.
It is a difficult mindset to change. When you do and act on that new mindset, the dividends it pays are enormous.
H&H Color Lab – American Company Growing Through Lean
H&H Color Lab began in the basement of Wayne and Shirley Haub’s residence in a suburb of Kansas City, Missouri, in 1970. Wayne and his brother, Ted Haub, owned a portrait studio that had just landed its first high school senior contract. With a background in and love for color printing, Wayne chose to install his own color processing equipment in the basement of his home.
Business increased, and so did the need for additional space and employees. What began with Wayne doing everything from his basement has grown to 165 people and 55,000 square feet of space over 40 years later.
H&H customers are primarily school/portrait/wedding photographers. The offer a wide range of products from photo prints to books to Leather bound albums and digital products.
In 1999, H&H Color Lab started is Lean journey led by Lee Gabbert. Lee had been with the company for 5 years at the time and was chosen to learn more about lean and teach others at H&H. They started by reading “Lean Thinking” by James Womack and Daniel Jones. H&H also decided to get a sensei to help them learn as they traveled the bumpy road down the lean path.
H&H Color Lab started by setting up work cells, going away from a department mentality. H&H moved to smaller batches, moving cells closer to the monuments (that they couldn’t move), standard work, and lots and lots of 5S.
Muda (waste), lead times, late work and quality all had improved. In fact, the gains from lean had now freed up space that was once occupied by manufacturing departments. It allowed H&H to take the space and use it as a training facility to help customers from all over the United States. Thus, H&H University was born. Roughly 3,000 square feet of space was now designed and transformed into a learning center, working photographic studio with equipment, mock up photography sales room, photography studio work area, kitchen to host all day training, library sitting room with sample products that H&H produce on the book shelves and restrooms. By providing training for customers (mostly free of charge), you truly can engage in a partnership that can grow.
All of this work allowed H&H Color Lab to make a success transition from the “Age of Film” to the “Digital Age”. Understanding their customers and providing training and education others companies do not, shows how the most important part of lean, focusing on the customer, helps you innovate, grow and thrive.
Here are results that H&H Color Lab have seen from their lean implementation.
