More Lessons from Toyota Industrial Equipment

The Toyota Industrial Equipment Manufacturing (TIEM) plant in Columbus, Indiana has more lessons for us as we continued our tour last Friday. Although you can never learn all that you want in just one day, a simple glimpse really, it was enough to spark my critical lean thinking into high gear.

One of the most striking things you see at this plant is what you don’t see. That is the almost complete absence of cardboard boxes and other dunnage typically found in manufacturing plants. All the parts are delivered to this plant in reusable/returnable containers. The same goes even for parts shipped in from Japan. It was interesting to see that the sides of the returnable containers from Japan were dual colored to visually display two difference orientations. The first orientation lets the totes stack, one atop the other. The second orientation allows the same totes to nest within each other to provide better density on the return trip.

Seeing this return container design makes the engineer in me imagine all kinds of possibilities that I may have not though possible before. It also makes me wonder if we should aggressively pursue the use of returnable containers, even to China. Everybody tells us it is too expensive and not logistically practical so we just ignore the possibility. Does anybody use returnable containers with their China suppliers?

The leaders of this plant are extremely proud, and rightly so, of their contribution to conservation of resources and their stewardship of the environment by becoming a landfill free facility. With the universal use of returnable container and a strong recycling program, TIEM does not send any waste to landfills. How many of our plants can say the same?

Toyota Industrial Equipment Manufacturing




I spend today, touring the Toyota Industrial Equipment Manufacturing (TIEM), facility located in Columbus, Indiana. Although this facility has been open since 1990 and within an hour drive of my home, I never had the opportunity to take an inside look at their operation before now. Thank you Toyota for opening your doors so we can learn.

Some of you may wonder if this company is part of the Toyota Motor Company or just a company using the Toyota name in a licensing agreement. Although they don’t build cars, they actually are part of the Toyota organization and follow the Toyota Way.

A few facts first:
99% of all the Toyota lift trucks sold in North America are manufactured in Columbus, Indiana.
Over 800 employees work to produce almost 30,000 trucks per year.
Over 60 different models are produced of electric lifts, 3,000 – 12,000 lbs and internal combustion lifts 3,000 – 17,000 lbs.
The facility covers 880,000 sq ft on about 101 acres of land.
The operations within this facility include metal fabrication, welding, powder coating, assembly and distribution.
Three main lines assembly lines currently run at various Takt times from 4.5 minutes to 33 minutes, adjusted monthly.




Now the lean lessons:
Each area holds a morning meeting (called “Asaichi Meeting”) for about 8 minutes to discuss the day’s schedule, safety issues, quality concerns, improvement ideas, company news and take attendance.

Right after this meeting, all the Team Leaders gather together to help each other face the challenges of achieving the daily production requirements. This meeting goes for about 6-8 minutes with attendance being the primary topic. Depending on who’s missing, the team leaders quickly agree on shifting associates to fill the gaps. A skill matrix chart helps them determine which associates have the required skills to fill the needs.

The Team leaders will reconvene every two hours during the entire shift to make sure everybody stays on the same page throughout the day.

The area will meet as a group at the end of the shift to review issues of the day. This meeting was called the “Yuichi Meeting” or pm meeting.

The meetings were conducted in front of the respective area’s measurement boards, called “Team Leader Control Boards” listing all the metrics like attendance, 5S, Kaizen newspapers, Defect lists, etc. The kaizen newspaper lists problems, the temporary countermeasure, the permanent countermeasure, who identified it, the planned date of completion and the actual date of completion. They also use the PDCA circle to visually show the four phases (investigation, find root cause, implement countermeasure, and standardize).

Each line has a master andon board that displays the daily production target, the actual number of units produced, lights for each workstation, the anticipated overtime for that day and a running time of any line stoppages. The workstation lights are yellow and red. When the yellow light flashes, it is a signal for needing help within a Takt Time. The red light signifies the line is stopped. In addition to the flashing lights, music is played. The line I observed played “It’s a small world” which I listened to several times today.

A cool idea was the formation of a kaizen group. This kaizen group consisted of 10 shop floor associates on a 6 month rotational assignment, all on a voluntary basis, to focus solely on helping implement kaizen ideas. They build carts, make labels, work on fixtures or work aids, etc. Really, they do whatever they can to get these ideas implemented.

Where do the kaizen ideas come from? They come from all the associates who are asked to come up with 3 ideas per associate per month (Think quick and easy kaizen). While Toyota encourages associates to implement their own improvement ideas, sometimes they need help. That’s where this kaizen group steps in.

There were more lessons that I will share in follow up posts but this will give you enough to think about for now.

This facility was not as organized or spotless as the Toyota Lexus plant I visited in Japan but none the less, a great plant to see the Toyota Way in action without having to go all the way to Japan.

Push versus Pull

"Under a push system, there is little opportunity for workers to gain wisdom because they just produce according to the instructions they are given. In contrast, a pull system asks the worker to use his or her head to come up with a manufacturing process where he or she alone must decide what needs to be made and how quickly it needs to be made. An environment where people have to think brings with it wisdom, and this wisdom brings with it kaizen (continuous improvement)." - Teruyuki Minoura, Senior Managing Director, Toyota Motor Company.

Improvement

"Improvement usually means doing something that we have never done before." -Shigeo Shingo

Prepare your Mind

“A relentless barrage of “why’s” is the best way to prepare your mind to pierce the clouded veil of thinking caused by the status quo. Use it often”
-Shigeo Shingo

Very early in our process improvement training, we are taught about the 5 why technique in problem solving. I have learned in my kaizen efforts, by simply asking why, numerous opportunities for process improvement can be found, potential root causes identified and countermeasures created.

In this quote from Shigeo Shingo’s book “Kaizen and the Art of Creative Thinking”, we hear about asking why again but for a different purpose. We can use the why questioning to prepare our minds. Think about that for a moment. By preparing our minds first, we break our mental barriers with the status quo. Until we do, we are not ready to realize, implement or accept any improvements.

What better way to prepare our minds than by asking why. Isn’t the process of asking why, the core essence of human development? Throughout human history, most of our progress can be linked to someone asking why (or why not, in some cases). Even as children, asking why is a central part of our mental development process. Asking a relentless barrage of why’s is a great way to open our mind, just ask any 3-6 year old.

Work in Progress Virus


As I take my Gemba Walk at a client site, I see a virus spreading at epidemic speeds in the offices and shopfloor. The virus is a simple “Work in Progress” sign posted above a work area, usually above a pile of material or individual workstation. What once started as a plea for fairness during 5S audits in one area has now spread across the entire organization.

Apparently, someone did not like getting a poor score on their 5S audit. Instead of using kaizen to improve it, they argued that the designated area should not be counted because it was in a constant state of disarray as a result of doing work. When a 5S auditor went along with the scheme, the “Work in Progress” sign was born as a free pass to overlook this area in a 5S Audit. Just like a virus, the “Work in Progress” signs started showing up everywhere. It is not a surprise to see the popularity of the signs. This approach is certainly easier than making an actual improvement but the wrong approach. (I did like the turtle to describe the flow).

Isn’t every square inch of our facility a place to do work with some stuff just moving faster than other stuff? Why don’t we put a sign over our front door declaring the whole building as work in progress and skip the 5S audit entirely? Don’t laugh. This was actually done over an entire department work area as a joke and the Auditor accepted it!



On our lean journey, it is easy to fall into traps like the immune “Work in Progress” designated areas and even boldly call the signs a visual management tool. Don’t be fooled. The lean principles are to be applied in every process, every function, and every square inch of our organization. There are no free passes, my friends.

Lean and Six Sigma's Effect on Complex Organizations

Last Wednesday night, I attend the APICS Chicago Chapter Monthly Professional Development Meeting to listen to Praveen Gupta, President of Accelper Consulting and author of many books including Six Sigma Business Scorecard and Virtually Stat Free Six Sigma, on his topic, Lean and Six Sigma’s effects on complex organizations.

Praveen’s insights on the applying improvement strategies in our increasingly complex organizations were thought provoking. From his point of view, our limited success in getting results from our improvement activities rests mainly on our approach (which has also gotten more complex) and not understanding the purpose behind our activities.

In his presentation, Praveen expanded on the book, The Goal, in modifying the goal of business from making money to the goal of business is to sustain profitable growth. In order to sustain profitable growth we need three things.

1. Any process improvement approach like Lean, six sigma, Lean/Sigma, etc.
2. A business scorecard to measure what we value.
3. Growth not dependant on Mergers and Acquisitions, but driven on innovation.

Praveen challenged us to avoid some of the traps of our current improvement approaches like:

1. Corporations not measuring sigma levels.
2. Leaders avoiding accountability of improvements activities to the bottom line.
3. Too much statistics entering into Six Sigma at the cost of product/process knowledge.

Praveen Gupta’s message for success:

“Standardize intent, customize methodology, utilize the right mix of tools and reduce the number of measurements.”

For more thoughts from Praveen Gupta, check out his long list of books, and look in Quality Digest Magazine for numerous articles he has published.

Kaizen and the Art of Creative Thinking


I just finished reading a truly great “new” book that explores the thinking process of making improvements, “Kaizen and the Art of Creative Thinking” written by Shigeo Shingo, published by Norman Bodek (PCS, Inc) and Collin McLoughlin (Enna Products Corporation). Actually, this is not really a new book since it was first written by Shigeo Shingo in 1958 but has never been translated in English before now. The official release date of this newly published English translation is set for October 15, 2007 and you can pre-order your copy here.

Knowing that the book was written back in 1958 caused me to wonder if any of the information would be relevant to today’s lean journey but after reading this book, I was not disappointed. Unlike the other great Shingo books which were more lean tool driven, “Kaizen and the Art of Creative Thinking” focuses on the thinking portion of problem solving, making improvements and meeting opposition to the guardians of the status quo. There are a great number of improvement examples in this book to clearly explain Shingo’s points which I found extremely helpful and entertaining. Some of the information has been written about before but there are plenty of new insights to make this book a must read for those of us on our lean journey.

The book confirms what I already knew to be true from my early days in lean when Shigeo Shingo taught me the SMED system. Shigeo Shingo is a genius and has a gift for teaching.

What can I do Today?

Being overwhelmed is a common feeling on the lean journey, especially as we become better at seeing all the wastes. When faced with long kaizen newspapers and seemingly endless kaizen opportunities, we ask the wrong questions like “How am I going to get this all done?”. We might think we don’t have the manpower or time to work on all these kaizen projects and employee suggestions with our current workload.

As a lean thinker, we change the way we look at those same kaizen opportunities. Ask the right question, “What can I do today?.

The Emotional Side of Lean

As we navigate our way in applying the lean principles within our own company cultures, value streams and business processes, it can sometimes feel like we are strapped in backwards on a roller coaster with a blindfold over our eyes. We experience a huge range of emotions and feelings in a short period of time including fear, panic, pain, excitement, hopefulness, uneasiness, pride, adrenaline rushes and frustration. Taking the path on a lean journey can be an extremely overwhelming experience.

There is plenty of technical information on the tools and concepts of lean but very little on the emotional side of lean. We tend to brush over the emotional issues associated with a lean transformation as nonexistent because this lean stuff is simple to understand so how hard can it be to just do it.

There is also a tendency to look down on anyone caught up in these emotions as wimps. In my earlier days on the lean journey, if we questioned any of the lean changes in our company we were called concrete heads or barriers. And anyone who did not get on board quickly found themselves looking for a new job.

In reflection, it was good to push us on the lean path because some of us would have never taken the first steps. We over came our emotions, struggled to get it right and eventually found ways to make it work. But I think it would have been a far better journey if the emotional side of lean was recognized.

By recognizing the emotional side of a lean transformation, we take the time to help employees mentally and emotionally embrace the lean approach. Some people easily embrace the lean approach while others struggle to accept it. When you have employees who hesitate making some of the lean changes, don’t tell them to trust you or just have faith. Unlike religion which is faith based, the lean approach is better accepted based on experience, experimentation and education.

Tell them, show them and let them learn by doing. Be a coach, providing endless encouragement and even a little pushing, to build confidence to go forward. Just like when our child first learns to walk, as parents, we cheer, encourage and praise our child’s attempts to take a single step. Even as our child stumbles and falls, we continue to cheer and extend our hands out to support them. Before long our child is taking several steps. We celebrate the success, taking pictures and videos. With more confidence and experience, our child learns to walk. Helping others on the lean journey should be no different, one step at a time.

Lean Tools for Maintenance & Reliability Conference 2007

There are several great lean conferences scheduled this fall including the Lean Tools for Maintenance & Reliability Conference set for October 1-3, 2007 in Cleveland, Ohio. Some of the great speakers lined up are from companies like Harley Davidson, Honda, Toyota and BMW to present case studies focusing on TPM, OEE and other lean maintenance topics. This is a great opportunity to learn more about lean and network with people who are currently on the lean journey. As a bonus, I am honored to have the opportunity to present some of my lean insights and experiences in one of the sessions. I hope you can join us.

We're Only as Good as Our Supply Chain

The best winning strategy for the future does not stop at our plant walls. Even if we are the most efficient manufacturer in our industry with the hottest products, our business will fail if we have a weak supply chain. We must extend our improvement efforts to include our supply chain.

Just look at the recently reported problems at Dell with their supply chain problems namely part shortages. Or just look at all the recent quality issues with products coming from China.

As labor costs decline as a percentage of product costs, we naturally start to focus on material costs for opportunities for improvement. Most companies up to now, play the games of “Beat up our Supplier” and “Chase the Globe for Lower Labor Cost” along with “Outsource it All”. Many companies have rightly earned a bad reputation with these strategies that aim solely at cost reductions at the expense of building a stronger supply chain. These companies will drop any of their suppliers to save a dime or less on piece part costs.

This method certainly has proven successful at pocketing some financial gains in the short run but will quickly cause deterioration in the supply chain. If we start to calculate the true cost of these methods over time, we may find out that our actual savings is much smaller than reported or even non-existent.

A better approach begins with completely changing our thinking of our supply chain. Our supply chain is the backbone of our value stream and everyone in the supply chain is linked together as partners. We are stronger when our suppliers are stronger. Toyota knows this lesson well.

As a valued partner, we should open our doors to our suppliers. We must share best practices, teach lean principles, coach and encourage continuous improvements. How many of our suppliers visit our facility? (I am not talking about sales reps) How about production, quality, engineering and even shop floor associates?

Do we invite our suppliers to join a kaizen event? Do we send our people to a supplier kaizen event? Do we communicate problems on a daily basis? Do we team together to solve problems or do we just send out formal corrective action requests? Do we listen to our suppliers?

It’s no longer good enough to just improve our internal processes. Our future success will not be based on how good we perform rather on how well our supply chain performs.

My First Toyota Sales Experience

There is no doubt that I am big fan of the Toyota Production System and the resulting Toyota vehicle product line. Despite these positive feelings, I have never owned a Toyota. Each time I am in the market for a new vehicle, I ended up buying a domestic brand including Buick, Chevy, Ford, and Dodge.

Yesterday, I went down to a Toyota Dealership in Indiana (name withheld) with a serious interest in buying a Toyota this time around. This was my first official Toyota sales contact although my wife visited Toyota dealerships before. All the vehicles were outstanding (I especially liked the newly redesigned Tundra). In direct contrast to the Toyota vehicles, my first time Toyota Sales Experience was not impressive.

Understanding that Toyota Motor Company does not own the dealerships and has no direct control over their operation, I suggest Toyota take a closer look at the dealership experience for kaizen. If Toyota can influence improvements in this experience, they can make a huge impact on continuing their growth. Otherwise, they may lose customers, not on the basis of the products but on the poor dealership experience.

The first major mistake was the arrogance of the Toyota Salesman. He hyped the Toyota products for features and engineering while slammed every domestic car manufacturing company and their products. We told him of our comparison shopping of other brands and he made us feel we were stupid to even consider them. Not a good sales technique! I was always taught NEVER to say bad things about any of your competitors. We even told him that we bought one of those terrible domestic vehicles in the past and it performed great. I guess we were just lucky?

The Toyota Salesman continued on his ego trip when we told him of another Toyota dealership my wife visited earlier in the week. He promptly pulled out some regional sales data sheet proudly showing his dealership ranking was extremely higher in number of vehicle sales than this other Toyota dealership. He continued his error by telling us that all he cares about is increasing the number of units sold to increase their ranking. I was a little stunned. Talk about results based management! What about us, the customer? Are we only a number to add to his tally sheet? Another poor sales method!

After working through the numbers (which did not change much from the list price), he tried the old “What will it take to get us to buy this vehicle today?” routine. We told him that we were going to look around and do comparison shopping before we made any decision. Yet, he pressed on with the pressure for a decision today.

The next poor experience was when we offered to trade in our vehicle. He did the routine vehicle check and asked us what we wanted for it. When we told him our expectation for the trade value, he laughed and stated that there was no way. We have a newer model, low miles, domestic vehicle with great options that we rated using both Kelly Blue Book and Edmunds. He offered us 35% less that the book value for our vehicle which was more of an insult to our intelligence than a good opening sales technique.

As we departed, we thanked him for his time. Before we even made it out of the showroom door, this salesman was off helping the next potential tally sheet addition in the sales lot.

Despite this poor sales experience, I will give other Toyota dealerships another chance. It would be unfair to judge all Toyota salesmen on this sample size of one but many other potential customers might not give them a second chance.

Do your meetings start and end on time?

On our lean journey, we sometimes overlook the simple and obvious wastes. Take meetings for example. How many of your meetings start and end on time? For the past several months, I recorded the FPY (First Pass Yield) rate of meetings starting on time that I attended ending up with a poor 0% FPY rate. Not one meeting started on time and very few ended on time.

How much muda (waste) is accepted in your companies on a daily basis just because we can not start and end meetings on time. Is this problem just too complex to solve or do we just accept this waste as a by product of doing business today?

Of course, we should eliminate all unnecessary meetings as a first step. Then demand, encourage, reward, promote and expect all meetings to start on time and end on time.

Prosperity

"If your want one year of prosperity, grow seeds.

If you want ten years of prosperity, grow trees.

If you want one hundred years of prosperity, grow people."

Chinese Proverb

Opportunity Calls

As I pulled into the company parking lot, a steady rain fell from the morning clouds. I made my way down the hall, turned on the office lights and fired up my laptop. After a quick email scan, it’s time for my gemba walk. Before I could make it out the door, my phone rings. It was the company VP of Operations and he was not happy.

Apparently, the President of the company went out on the shop floor late yesterday afternoon and found a couple of issues related to our lean efforts. The President naturally passed these concerns to the VP and now to me.

“Mike, we have some problems.” said the VP with a serious tone. I quickly answered.” That’s great news!”

We Need Human Andons

With my last post on andon lights, I pointed out the seemingly widespread misuse of this simple visual tool. More importantly, we don’t stop to fix the problems and problems remain hidden. Andon lights are just tools. The real mission is the quick identification of all the interruptions to process flow and the speedy countermeasures to prevent the problems from occurring in the future. What we really need is human andons.

How many times do you or your employees see a problem and quietly fix it?

Is this the right thing to do?

Did you really fix the problem so it does not appear again or just fixed it this time?

Is the company in a better position by this approach?

Do these problems show up again later in the day? Tomorrow? Next week?

What if, starting immediately, every single employee in your company with every single task and every single process, takes on the additional role of human andon by identifying every single occurrence of interruption to the flow?

Would you be surprised by the results? A little overwhelming to think about the potential staggering number of flow interruptions our employees deal with every single day.

But think of all the opportunities for improvement? Call it kaizen heaven.

For some lingering reasons from the traditional management school of thinking, we do not welcome the news of problems. We prefer to hear only good news. We glorify news of some miraculous feats of managerial leadership that “pulled out all the stops, to muscle the order through the shop” but don’t talk about the problems encountered and countermeasures to prevent them. We still are caught up in placing blame for problems.

Until we removed the current equation (Problems = Blame) from our mindset and replace it with the lean thinkers equation (Problems = Opportunities), we can not go forward on our journey.

Andon Lights Make Us Look Lean

After visiting and working at numerous manufacturing plants across the United States this past year, I have come to the conclusion that we really don’t know how to use an andon light properly much less know why we should use them. In most cases, the lights are pointed out as one of the indicators that the plant does know about lean and practices lean principles. In these same plants, I see other things.

I have seen andon lights turned on and stay green all shift long regardless of multiple problems occurring. (Could it be possible the management yelled about the line stops and flashing lights so much that everybody is now afraid to pull the cord?)

I have seen andon lights turn on but all the bulbs were burned out rendering the light useless. (Maybe we should also work on our 5S audit program, lack of gemba walks and poor TPM program?).

I have seen andon lights flash and blink for hours but not one person comes running. (Why does the signal for help go unanswered and why don’t we look into the causes for the long delays?)

I have seen huge multi-stacked andon lights that nobody seems to remember why each color was needed. (How can we make the andon light system simpler?)

I have even seen andon lights used in shop floor pranks just to watch people frantically run around for the humor of the guilty light switch pullers. (Maybe we should read the story about the boy that cried wolf at our next shift meeting?)

Here is a simple visual signal that could improve awareness and responsiveness on the shop floor yet we don’t take the time to properly train and use this tool for its intended function. Just having andon lights is not an indication of being lean; it only helps make problems visible along with promoting the goal of FAST response.

I guess we have taken to heart what my old junior high football coach would regularly say to us on game day, “Boys, keep your jerseys tucked in and your socks pulled up. If you can’t play well, at least you are going to look like you can play well.”

New Lean Survey 5 Why Style

Thanks to the lean thinking approach of Mark Graban from the Lean Blog, there is a new 5 Why type lean survey under experimentation to address the limits of typical surveys. This all started from the results of the Lean Enterprise Institute 2007 State of Lean Survey. Please give it a try-link to survey.

Middle Managers are Biggest Obstacle to Lean Enterprise

According to the 2007 State of Lean Survey conducted by the Lean Enterprise Institute, the number one ranked obstacle to implementing lean is middle management resistance to change, jumping up from number three in last years survey.

Last years number one reported obstacle was backsliding which dropped all the way down to sixth place in this year’s survey.

It seems to be an interesting shift in just one year that it appears most respondents now can sustain gains better but must deal with the “concrete heads” of middle management to progress on their lean journey.

As a lean practitioner in the field working closely with several major clients, I have my own opinion on barriers to the lean journey. What about your obstacles to progress on your lean journey? Do you agree with these finding?

This survey was completed by 2,444 managers and executives within the base of LEI’s monthly e-letter subscribers. I wonder what the mix of senior level executives to lower level lean practitioners is within the 2,444 respondents. I see middle management resistance, employee resistance and supervisor resistance all making three of the top four obstacles to lean. Do you find that odd? Notice anyone missing from the list? Make me say, ummmmmmm!

From a senior executive point of view, I would say we could be a great lean company if it wasn’t for all our middle managers, supervisors and employees resisting change. Looks like the bus needs to makes a bus stop to let some (a lot of) people off. To make it more complete, how about adding supplier resistance and unreasonable customer demands to the list?

As a lean thinker, I find this difficult to believe. First, I would ask five whys to get deeper at the root cause of the obstacles to lean. It is not the five-who process to find the root blame. Until we stop trying to pin blame on someone else, we will not make progress on our lean journey. It is better that we should reflect on our own thinking and actions to see what obstacles we create and fix them first.

Despite my issues with the survey findings, LEI does an outstanding job promoting and teaching lean thinking along with helping organization on their lean journey. For more information, visit LEI at http://www.lean.org/.
