Sayings of the Lean Fathers

Within the body of Jewish literature,  there is a book called "Pirke Avot", which means 'Sayings of the Fathers'. It is a collection of wisdom and quotes handed down from the ancient rabbis and the Jewish tradition. Taking that reference as a model, I decided to produce this "Sayings of the Lean Fathers." Enjoy!

Taiichi Ohno

(February 29, 1912 – May 28, 1990) was a Japanese industrial engineer and businessman. He is considered to be the father of the Toyota Production System, which became Lean Manufacturing in the U.S. He devised the seven wastes (or muda in Japanese) as part of this system. He wrote several books about the system, including Toyota Production System: Beyond Large-Scale Production.   https://es.wikipedia.org/wiki/Taiichi_Ohno 

We are doomed to failure without a daily destruction of our various preconceptions.

Progress cannot be generated when we are satisfied with existing situations.

Start from need.

Having no problems is the biggest problem of all.

If you assume that things are all right the way they are, you can’t do Kaizen. So change something!

Ask 'why' five times about every matter.

Why not make work easier and more interesting, so people do not have to sweat? The Toyota style is not to create results by working hard. It is a system that says there is no limit to people’s creativity. People don’t go to Toyota to ‘work’, they go there to ‘think’.

Without standards, there can be no improvement.

Where there is no Standard there can be no Kaizen.

Standards should not be forced down from above but rather set by the production workers themselves.

Make your workplace into showcase that can be understood by everyone at a glance. In terms of quality, it means to make the defects immediately apparent. In terms of quantity, it means that progress or delay, measured against the plan, is made immediately apparent. When this is done, problems can be discovered immediately, and everyone can initiate improvement plans.

The slower but consistent tortoise causes less waste and is more desirable than the speedy hare that races ahead and then stops occasionally to doze. The Toyota Production System can be realized only when all the workers become tortoises.

All we are doing is looking at the time line, from the moment a customer gives us an order to the point we collect the cash. And, we are reducing the time line by reducing the non-value-added wastes.

Something is wrong if workers do not look around each day, find things that are tedious or boring, and then rewrite the procedures. Even last month's manual should be out of date.

The more inventory a company has, the less likely they will have what they need.
We are doomed to failure without a daily destruction of our various preconceptions.

The key to the Toyota Way and what makes Toyota stand out is not any of the individual elements…But what is important is having all the elements together as a system. It must be practiced every day in a very consistent manner, not in spurts.

If you are going to do TPS you must do it all the way. You also need to change the way you think. You need to change how you look at things.

The only place that work and motion are the same thing is the zoo where people pay to see the animals move around.

People who can’t understand numbers are useless. The gemba where numbers are not visible is also bad. However,  people who only look at numbers are the worst of all.

W. Edwards Deming

(October 14, 1900 – December 20, 1993) was an American engineer, statistician, professor, author, lecturer, and management consultant. Educated initially as an electrical engineer and later specializing in mathematical physics, he helped develop the sampling techniques still used by the U.S. Department of the Census and the Bureau of Labor Statistics. In his book, The New Economics for Industry, Government, and Education, Deming championed the work of Walter Shewhart, including statistical process control, operational definitions, and what Deming called the "Shewhart Cycle" which had evolved into PDSA (Plan-Do-Study-Act). This was in response to the growing popularity of PDCA, which Deming viewed as tampering with the meaning of Shewhart's original work. Deming is best known for his work in Japan after WWII, particularly his work with the leaders of Japanese industry.    https://en.wikipedia.org/wiki/W._Edwards_Deming

People are entitled to joy in work.

Management by results -- like driving a car by looking in rear view mirror.

It is not necessary to change. Survival is not mandatory.

The greatest waste in America is failure to use the abilities of people.

The moral is that it is necessary to innovate, to predict needs of the customer, give him more. He that innovates and is lucky will take the market.

The consumer is the most important point on the production-line.

Export anything to a friendly country except American management.

Whenever there is fear, you will get wrong figures.

A bad system will beat a good person every time.

To manage one must lead. To lead, one must understand the work that he and his people are responsible for.

Does experience help? No! Not if we are doing the wrong things.

The supposition is prevalent the world over that there would be no problems in production or service if only our production workers would do their jobs in the way that they were taught. Pleasant dreams. The workers are handicapped by the system, and the system belongs to the management.

Defects are not free. Somebody makes them, and gets paid for making them.

Every system is perfectly designed to get the results it gets.

A leader is a coach, not a judge.

Pay is not a motivator.

The merit rating nourishes short-term performance, annihilates long-term planning, builds fear, demolishes teamwork, [and] nourishes rivalry and politics. It leaves people bitter, crushed, bruised, battered, desolate, despondent, dejected, feeling inferior, some even depressed, unfit for work for weeks after receipt of rating, unable to comprehend why they are inferior. It is unfair, as it ascribes to the people in a group differences that may be caused totally by the system that they work in.

Quality is made in the board room. A worker can deliver lower quality, but she cannot deliver quality better than the system allows.

Shigeo Shingo

 (1909 - 1990), born in Saga City, Japan, was a Japanese industrial engineer who is considered as the world’s leading expert on manufacturing practices and the Toyota Production System.      https://en.wikipedia.org/wiki/Shigeo_Shingo

Lean is a way of thinking- not a list of things to do.

The most dangerous kind of waste is the waste we do not recognize.

Are you too busy for improvement? Frequently, I am rebuffed by people who say they are too busy and have no time for such activities. I make it a point to respond by telling people, look, you’ll stop being busy either when you die or when the company goes bankrupt.

Unless you change direction, you will end up where you are headed.

We have to grasp not only the Know-How but also 'Know Why', if we want to master the Toyota Production System.

Those who are not dissatisfied will never make any progress.

There are four purposes of improvement: easier, better, faster, and cheaper. These four goals appear in the order of priority.

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.

Masaaki Imai

(born, 1930) is a Japanese organizational theorist and management consultant, known for his work on quality management, specifically on Kaizen.     https://en.wikipedia.org/wiki/Masaaki_Imai

The message of the Kaizen strategy is that not a day should go by without some kind of improvement being made somewhere in the company.

The Kaizen Philosophy assumes that our way of life - be it our working life, our social life, or our home life - deserves to be constantly improved.

It is impossible to improve any process until it is standardized. If the process is shifting from here to there, then any improvement will just be one more variation that is occasionally used and mostly ignored. One must standardize, and thus stabilize the process, before continuous improvement can be made.

Progress is impossible without the ability to admit mistakes.

The standard is not written on the stone. The definition of the standard is that it is the best way to do the job for now. It should be regarded as a next step to make further improvement.

Where there is no standard, there can be no improvement. For these reasons, standards are the basis for both maintenance and improvement.

Kaizen means ongoing improvement involving everybody, without spending much money.

I believe that management should focus on two particular areas. One is Gemba (shop floor) and the other is customer (not the shareholder).

You can't do kaizen just once or twice and expect immediate results. You have to be in it for the long haul.

All of management's efforts for Kaizen boil down to two words: customer satisfaction.

I have a theory that among the large Western companies (mostly American) the higher an executive is promoted, the more wisdom is lost and by the time he or she reaches the top becomes a complete idiot. Certainly they do not deserve the outrageous salary.

Japanese management practices succeed simply because they are good management practices. This success has little to do with cultural factors. And the lack of cultural bias means that these practices can be - and are - just as successfully employed elsewhere.

Kaizen is like a hotbed that nurtures small and ongoing changes, while innovation is like magma that appears in abrupt eruptions from time to time.

Under the lean system, any tools which are required for solving problems are used.

This Kanban System Works

Several months ago, I helped a practice set up a small, experimental kanban system for drug inventory. This particular system uses a kanban card as the signal to re-order.

The other common system utilizes two bins to hold a predetermined amount of product. When the first bin is empty, it is  removed and placed in a specified place known as a kanban post. From here, someone routinely (determined by standardized work) collects the empty bins and refills them from a central supply area. These bins are then returned and placed under (behind) the bin currently in use. The cycle repeats. This type of system is most often utilized in work areas, such as exam rooms, treatment areas or the lab to manage syringes, blood tubes, gauze squares, microscope slides, etc.

This was the “system” that was used previously. Excess drugs were stored throughout the hospital wherever there was room, such as this exam room cabinet. Notice the somewhat haphazard way the bottles are arranged.  Nothing is labeled. There are two empty slots on the second shelf. What is missing and needs to be ordered? And, how many? How long has this shortage been going on?

This “system” requires a staff member to go to all the the different “nooks and crannies” in order to create a complete drug order. In addition, this person would need to be experienced enough to “know” what belongs in empty spaces and how many to order. Inventory must be taken daily in order to identify depleted drugs, and get them ordered and delivered, hopefully, before a doctor needs to prescribed them. There is no reserved supply to cover the time necessary to get a new order in. Fortunately, for this hospital, orders placed by 10:00a.m. would be delivered by 3:00p.m. Not horrible, but still a gap before anyone can use the drug. For many hospitals, the lead time is days, not hours. Daily ordering also means daily receiving, daily invoice reconciliation, and daily restocking of shelves. That’s a lot of muda (waste)!!

In the new system, a place was found to install a couple of shelf units to experiment with. The drugs and supplies chosen were arranged in alphabetical order, with a few spaces left open for future additions.

The front of the shelves were labeled for each item. A place for everything, and everything in its place!

Even at this point, a missing item would be noticeable and identifiable.

The final step was making and placing the kanban cards (the signals). In order to keep this experiment as inexpensive as possible and to allow for quick, easy changes, I used pink index cards. The cards were bent in an “L” shape so they would stand up and be more visible.

On the front of the cards, I wrote the name of the drug, its size (e.g. milligrams), the unit size (e.g. tablets per bottle), the number of units to order and the number of units to keep behind the card. Our goal with this system was to only need to order once weekly. We wanted no more than two months supply up front, if possible, and, at least, one week's worth behind the card. When a new order comes in, the inventory is rotated by placing the items behind the card in front and replacing the reserve stock behind; a FIFO ( First In, First Out) system.

Now, once a week, a staff member (any staff member, because the system makes this possible) looks at the shelves and records the item, size and quantity to order. Ba-da-bing, ba-da-boom!

An improvement experiment might be to place a bar code on the card and read it with a smartphone or tablet into a form to be faxed or transmitted directly into a vendor's ordering software.

There are several Lean concepts here.

1. It is visual. With a single glance and one can see what is needed and what is not.
2. Just-In-Time. Item are only ordered when they are needed and in the amount needed, but before they run out completely.
3. Elimination of waste (muda). Wasted time in ordering, receiving, reconciling  and shelving, i.e. once weekly vs once daily. Wasted space in warehousing large amounts of inventory. Wasted use of capital that might be needed for other situations. And, wasted transportation and motion by the vendor. Increased workload on the rest of the staff to “cover” for an employee to handle inventory on a daily basis.
4. Use of  small, inexpensive, manual systems to experiment with and work out the “bugs” before investing in and expanding the system to include all other drugs or supplies, such as office supplies, or implementing more advanced technology, such as expensive and cumbersome software.

I had the opportunity to speak with the doctors and staff last month. They are still using the system and admitted that it has resulted in near zero shortages of these drugs. They were planning to expand it to other areas in the very near future.

Einstein's Equation of Lean Relativity

No, not Albert Einstein! Moraito “Morey” Einstein, Albert’s third cousin, twice removed on his mother’s side.

Just kidding! However, this, in a simple equation, explains Lean.

“F” stands for Flow and “V” stands for Value from the client’s point of view.

Taiichi Ohno’s equation states:

                                      Capacity = Work + Waste

What this equation states is that there is always waste in our current state. When we remove some waste, we create a new current state, but there is still waste. We pursue perfection, but never achieve perfection.

If we substitute our total “Value Streams” for “Present Capacity” and “Flow” for “Work”, we get:

                                     Value Streams = Flow + Waste

Rewriting the equation gives us:

                                     Flow = Value Streams - Waste



This, then, is essentially what flow means. Flow is all the different processes (value streams) that occur in the management of a veterinary practice with as much waste removed as possible (and then continually improved).

Also, remember that Value is defined as that which a client desires (Dc) and is willing to pay for, that moves (Mp) the patient's condition toward the desired outcome and is performed correctly (without waste; W) the first time.

                                           V = Dc + Mp - W


Everything about Lean is about improving flow, because flow ultimately results in greater value. A3 problem solving, 5S projects, kanban, Just-In-Time (JIT) concepts, error proofing (jidoka), visual management, continuous improvement (kaizen), everything is aimed at pursuing the perfection of flow. We continually improve systems and processes in order to improve flow, and therefore, value. 5S organizes the hospital by removing clutter from work areas, organizing the areas so that they have only the needed equipment close to hand with a consistent place for everything and everything in its place. 5S also makes problems visible, and solving those problems allows us to improve flow.

For example, at our hospital we were constantly having to leave the exams rooms to find this or that item. Not good for flow! So, we went to each of the exam rooms and got rid of duplicate suture scissors, hemostats, tourniquets, etc. Then, the staff and I created a list of the supplies and instruments that we routinely use within the rooms. We chose a roll of tape, Vetrap, cotton swabs, gauze squares, clippers, a small supply of various syringes, a digital thermometer, a Nye tourniquet, a stethoscope, fecal loops, etc. We even put some blood tubes, Idexx spinners, and a bottle of heparin in each room to facilitate quick blood draws for lab tests. Finally, we organized the drawers so that they were the same in each exam room. Now, each room is the same, with the most used resources close at hand. In addition, we all now know, regardless of which room we’re in, that tape is in the right hand drawer and the tourniquet is in the left. There is less confusion. We don't have to think, “This is exam room 1, so the suture scissors are here...no, there...no, in that drawer.” There’s no more time spent searching for items. Also, doctors and/or staff can now quickly (visually) tell if the drawers are complete (standardized). If not, the problem is fixed right then so it doesn't continue to be a disruption. This improves flow, thus value.

Kanban and JIT improve resource utilization by creating a system that provides drugs, supplies, staff schedules and doctor’s time, to name a few, only when needed, where needed and in the amount needed. This frees up cash, space, staff and doctors to do more patient care which improves flow which equates with higher value. Visual management techniques, A3 (PDSA) thinking, and “5 Whys” root cause analysis allow problems to be easily seen and fixed at the root cause(s), again, in order to improve flow and value. Even kaizen, the concept of utilizing our ultimate resource, our staff, to identify and fix problems and remove waste (muda) from our value streams is for the purpose of perfecting flow.

Time is money. And, time spent on wasteful activities and processes is money lost. Everything in our hospital, even wasted items, has to be paid for through income from clients. Otherwise, it comes out of our pockets, our bottom line. Value from the client's perspective means not being charged higher fees in order to cover waste.


All of this, then, is contained in the equation F=V. Simple, right?

The different individual concepts and “tools” of Lean are relatively simple. The difficulty is conceptualizing how the different elements interrelate to create Lean, putting it into operation within your practice and, then sustaining it long enough to get positive results and change the organizational mindset to automatically think Lean. But, that is a different equation and a different blog!

For now, just remember, “it's all about da flow, ‘bout da flow, ‘bout da flow…!“

What are your thoughts? Let us know.

Visual Management

5S is just one example of a Lean concept called “visual management.” We can also think of visual management as a form of “standardized work” for everyone in the practice.

As explained in the book Lean Hospitals (3rd edition), the goal of visual management is to make waste, problems and abnormal conditions readily apparent to employees and managers. As Fujio Cho, honorary chairman of Toyota says, “One of the worst situations… is not being able to tell whether things are standard or out of standard (normal or abnormal).” Our aim should be to expose problems so they can be fixed, as opposed to the old approach of hiding problems to make things look good. Jamie Bonini of the Toyota Production System Support Center organization says, "The ideal is to be notified of any abnormality immediately and to solve problems as they occur, while the situation is still fresh."

Visual management has two main tenets: first, make problems or status visible; and, second, manage those situations, reacting as needed in the short term and solving root causes of those problems over the longer term. Even before Lean, healthcare organizations might put multi-colored plastic “flags” up in the hallway outside each exam room. These flags, if used consistently by staff, can provide a clear visual indicator that answer questions such as, “Is there a client in that room yet?” or “Where does Dr. Y need to go next?”

While visual management is ideally used for real-time decision making and problem solving, Lean organizations tend to also post performance measures (or metrics) on the wall for everybody to see. Understanding the performance of a practice (in areas such as safety, quality, patient satisfaction, or financials) can help everybody focus their kaizen improvement efforts (as described later). Posting metrics cannot become an exercise in blaming or just pressuring people to perform better. Everybody must work together to improve the systems and processes that lead to those results.
