Why Lean Is Important: From An Informed Client's Perspective

Today's post comes from Gerald Cronin of the Vivarium Operational Excellence (VOE) Network.

The VOE Network is a worldwide group of Lab Animal and Biomedical veterinarians and experts that have discovered and been successfully utilizing the Toyota Production System, or Lean,  to reduce valuable research costs while at the same time improve research quality and animal quality of life. 

From thier own website:

"Every modern industry and organization has been influenced by the operational advances of the Toyota Production System, the thinking that made Toyota the #1 auto manufacturer in the world.   Decades of research has proven that Toyota's systematic approach to improving operations has tangible long-term benefits to customer service, quality, productivity, adaptability and ultimately to reduce costs."

"The Biomedical Research community recognized these advances over a decade ago and thus began the adaptation of systematic continuous improvement techniques to the Lab Animal Industry.  Consistent with Toyota's philosophy of "sharing what they have learned from over 50 years of experimentation with the world", the Biomedical Research community understood that together, we could improve operations better, faster, cheaper if we shared our knowledge with each other." 

"With over a decade of experience, the VOE-Network was born to help the entire animal care community improve operations through members' experimentation, learning and sharing."

"The Vivarium Operational Excellence Network is a consortium of animal care institutions and companies committed to quality clinical and veterinary research driven by operational excellence.  We are a members-run organization that responds to the evolving learning needs of its members.  Learning spans the organizational spectrum from front-line technicians through Webinars, videos and Lean Belt certification to leadership skills gained from our Leadership Academy events and offerings.  We also look to industry for insights into the best ways to improve operations as well as ways to build a problem-solving culture."

Today's post:

I took my dog to a large Veterinary practice about a year ago and needed to use the restroom.  The restroom was tucked inside the clinical staff area, so I needed to navigate through some hallways to get to where I needed to be.  Along the way, I was able to see “behind the curtain” of this operation.  I was disturbed to see rooms full of medical supplies in random areas, cardboard boxes both opened and unopened piled on top of each other, medical devices stacked on top of unfolded towels and on top of unopened boxes, there was almost zero floorspace for staff to move around.  Random bottles that looked to contain some sort of medication were in random locations.  Then there was the office with piles of paperwork, computer terminals were poking through the mess, almost as if they were struggling for air.
The staff was walking from room to room and asking each other “have you seen the (X clinical item)?”  “Did you call Mrs McGillicuddy or was I supposed to”? “Sorry for the wait, Mr. Cronin, we’re really busy today” and “We will need to schedule your next appointment, we were hoping the machine would be ready today, but it’s in need of maintenance”.

I made it to the restroom and got to see more of the same on the way back. The trip made me pause, as I now questioned the quality of care my dog was about to receive.  I’m also thinking about what I was going to get billed for and why I need to come back. Piles of inventory and random clutter, medications that didn’t seem to belong there, medical devices mixed with cardboard boxes filled with supplies 3-boxes deep.  Machines that should be operational but are not. The red flags were popping up everywhere.  What am I paying for?  Can I trust this clinic?  Who can I trust here? Do they know what they are doing?

You can tell a lot from what you see in a clinic. Maybe some of the judgements are assumptions, but often they are pretty accurate. The telltale signs of disorganization, the questions staff ask each other, the delays, the missed information, the clusters of inventory that often contains expired materials; all give me the chills, no matter if I’m going for my annual physical or if I’m taking my dog to the Vet.   To me, the paying customer, they all tell a story of wasteful processes that I know are built into my bill.

I’ve been a Lean practitioner in healthcare for a few years, watching and helping clinical teams improve their care to the patient in the bed. If they can do more for the patient in a better, easier way, they are all over it.  I now work in the Veterinary world, and I have seen amazing transformations of quality of animal care and improvements to the Veterinary staff quality-of-life by focusing on improving small (sometimes tiny) process that support their daily work.  It’s so exciting to see folks enjoy the teeny challenges of improving their own work. Lousy processes are like “pebbles in your shoe”; workers agonize through the customs and clutter; given the chance, they would stop and remove the pebble to make life better.  Lean thinking does just that for workers, and the animals and their owners benefit exponentially. 

If you ever feel frustrated, rushed, frazzled, buried by complaints, or workers constantly asking questions looking for “common sense’ answers, the prescription may not be buried in a store room or office, but right here, sitting out in the open at no charge to you.  The world of Lean thinking is liberating, and Lean thinkers are eager to share their learnings and experiences with you.  We are here to help you; we’ve all been through the same frustrations and we found the prescription.  Take one small dose daily; you will be amazed at how your quality of life will improve. (My dog is OK by the way).

R-E-S-P-E-C-T

“Respect for people” is a fundamental principle of Lean and a major difference between Lean and the Western, more Taylor-esque, concept of management. The Western tradition, which is still a part of educating MBAs, is that management knows best and makes all decisions. Workers are to do as they are told.

There is a quotation by Henry Ford to the effect that the problem with workers is that, not only do they come with two hands, but also, unfortunately, a brain. Workers are not hired to think! Lean is much less of a top-down style of management, and much more of a bottom-up, inclusive, transparent style. This is not to say, however, that the asylum is completely handed over to the patients.

This core belief influences the relationship Toyota managers and supervisors have with their workers. For Toyota, management’s primary function is more of teacher and less of an organizational police officer. We now understand, more than before, that the focus for Toyota is not just on building quality automobiles, it is primarily focused on the building of problem solving, innovative, respected employees who, then, build quality, innovative automobiles.

Dealing with people from a basis of respect permeates every aspect of Lean.

Systems thinking:

Have you ever had the feeling that, at some point at work, you were damned if you do and damned if you don't? Or, that you are in the the middle of a Catch-22 situation? If so, you have probably been the victim of poor systems or systems colliding with each other. That feeling of not being in control or at the mercy of things bigger than you.

Thinking in terms of systems means understanding that the systems at work within an organization are management and leadership designed. Systems are the responsibility of management. Workers have no authority to control or overhaul systems. They are at the mercy of the systems. Yet, many times, staff are blamed for what is, in actuality, a system design problem.

For example, if a job is not being performed well, systems thinking would first consider such things as does the worker know that job is their responsibility, has the worker been trained adequately, does the worker have the necessary tools, and does the worker have timely and correct information?

Systems thinking is more respectful. It recognizes that systems should be investigated when problems occur before blaming people.

Value:

The Lean definition of value is that which the client wants and is willing to pay for, and that improves the health status of the pet, without defects and waste along the way. Our clients get exactly what they want, when want it and in the amount wanted. They pay for only value adding services. The concept of defining value from the client’s point of view shows respect for them.

Variance and overburdening:

Lean understands that large variances in workload can be the source of difficulties and overburden our staff. Lean suggests work loads try to be leveled as much as possible. Being watchful for the overburdening of staff comes from respect.

Just-In-Time

The Just-In-Time (JIT) concept is the procurement and delivery of resources, (whether that be drugs, supplies, access to diagnostic equipment and information, or patients, doctors and staff) just exactly where it is needed, just exactly when it is needed, and just exactly in the amount needed. Nothing more and nothing less.

With respect to staff and personnel, the Just-In-Time idea is based, in part, on recognizing and respecting the unique value of everyone's time and skills; to only use them when, where and in the amount needed.

Standardized work

Standardized work is the mutually agreed upon method to do or handle a certain process or situation that helps insure quality, timeliness and safety, and gets everyone on the same page working in the same direction. It shows respect by involving staff in its definition and formal writing, and by eliminating ambiguity and the anxiety it causes to workers that come from policy and process chaos.

Kaizen

Kaizen is a Japanese word that can be translated to mean “good change,” “change for the better,” or “continuous improvement.”

While improvements can be large, time consuming and expensive major changes, the most common are the small, daily, quick, inexpensive ideas submitted by staff that improve quality, flow, safety, value to the client and make work life just a little easier. Staff are on the frontline of our practices every minute of every day. They know, better than anyone, where and what the problems are. And, they probably know better how to remedy them than we owners and managers do.

Kaizen shows respect by recognizing what an asset our staff is, and allowing them to partner with us in improving the practice; to be engaged and be part of the solutions, rather than always being blamed for the problems.

5S

5S projects are the physical cleaning and reorganization of a particular room or area of the practice. It helps the staff to work with less clutter, frustration and confusion on a daily basis. It creates better flow within the hospital which increase value to clients; all ways of showing respect.

Go to gemba

"Genchi Genbutsu" (go and see) means that whenever there is a problem found, all relevant stakeholders (management and staff) should go to where the problem occurs (the “gemba”) and solve it together. It shows respect by recognizing that staff have valuable input to the situation.  

The Andon cord

On the Toyota production line, workers are provided with a mechanism to sound an alarm and ask for help anytime they find it necessary. The line stops if the problem is not quickly resolved. Toyota trains and trusts its employees to use the Andon cord when an issue of quality or safety is in question. It shows respect by creating a culture of safety and trust for anyone to speak up, even if they think there might possibly be an inkling of a concern.

It is my humble opinion that if veterinary staffs knew about and understood the Lean mindset and its worker-centric (and client-centric) philosophy, there would be such a grassroots revolution within the profession that owners, managers and corporation leadership would have no choice but to start thinking Lean within their practices. Maybe, we could start now and circumvent all of the "bloodshed."

A Response To a Comment About My Post "Lean Self"

Last month, shortly after my blog on the “Lean Self”, my friend and mentor Mark Graban posted a comment to that blog. This was unusual.  Usually, Mark emails his questions and points of concern to me after receiving my final draft of the blog post, but before I publish the final, final draft. His questions sometimes come from sheer confusion about what it is ‘that I am really trying to say’, but many times it is his way of teaching in the Socratic (and Toyota) method. That is, rather than lecturing, asking the student a series of questions that lead the student to discovering the answer or reflecting deeper on the subject. Occasionally, I am not sure which it is.

I have decided to answer in another blog post, rather than a reply to the comment that may go unnoticed.

Mark comments:

Thanks for sharing this, Chip.

I agree that having a personal “true north” and understanding your own “current state” can be beneficial.  I don't quite see how to apply the idea of a “value stream” though. What is “value?” How does it flow? How do you see that connection in one’s personal life?

Mark

Here is my response.

Mark, thank you for your comments. Please forgive my tardiness in replying. I have been recovering from a little bit of surgery.

Your questions have caused me to re-evaluate my premise as regards extrapolating the Lean mindset to the “self.” As they should.

What is ‘value’ in this context?

Another way to arrive at an answer to this question is to ask, “What is really important to you in healthcare?” Or, “What is really important to you in a car?” For the “self” it would be, “What is really important to you in your life?” I think (hope!?) for most people it would be “contentment.” To be contented financially. To be content at work. To be content in our relationships.  To be content with ourselves. The Hebrew word “shalom” is generally translated as meaning “peace.” And it does, but it is the peace that comes from being “whole” (content spiritually, physically, emotionally, psychologically); not having excess or being destitute, but from having enough or being grateful with what you do have.

Part of the Lean definition of “value” is that the customer be willing to pay for it. If you are not willing to put a price on what you want, it doesn’t really hold any value. This holds true for the “self”, also. But, it doesn’t necessarily mean money. It means doing the hard work of honest self reflection, letting go of false assumptions, admitting mistakes, mending relationships, simplifying, budgeting, pushing back the ego, stepping out of the forest and,then, prioritizing and starting, somewhere, on a lifelong journey of improvement.

What is the “value stream’?

The Lean concept of the “value stream” requires, amongst other things, a provider, a customer and a “gemba” (the place where the work actually occurs). Unlike other applications of Lean where the provider and customer are separate entities, for the “self” they are the same, us. And the “gemba” is our hearts and minds.

The steps we go through in our hearts, minds and lives to get whatever value we get is the “value stream”. Whether that process results in contentment or “dis-ease” in a particular area of our life depends on how much muda (waste, i.e. faulty thinking, biases, rewritten history, skewed priorities, energy vampires, B**l S**t, etc.) is embedded. Graphically representing this thought process produces a “value stream map”

For example: I must be perfect →  I burned the turkey → I’m a bad cook → I’m a lousy wife → I’m a bad person.  Not good “flow.” Lots of bad processes and “trash.” What’s the value here?

Note that using 5 Why might take you back through this process. For example:

     Why are you a bad person?  Because, I am a lousy wife.

     Why are you a lousy wife? Because, I am a bad cook.

     Why are you a bad cook? Because, I burned the turkey AND I must be perfect!

BINGO!! A possible root cause. The false belief that “I must be perfect!”!

Now, to be able to map this current state value stream may not be easy and it may require the help of “stakeholders” (others who have our best interest at heart). And, just as in any other Lean application, finding the “waste” in order to produce a better future value stream will work best if our “stakeholders” are given access to our gemba and are present; if we are open, honest and communicative about what is going on inside of us and in our lives.

Thus, I think the Lean concepts of value, true North, gemba, current value stream, future value stream, A3 thinking, 5S, 5 Why and kaizen are just as valid working on improving ourselves as it is in improving manufacturing, service industries, healthcare, etc. for the customer- us!

Lean Self

One of the aspects of the Lean methodology that I appreciate most of all is the breadth of its  application. Lean is applicable to manufacturing, retail, service businesses, professional associations (Nudge, nudge AVMA!), human healthcare, dental practice and veterinary practice. It can even be extrapolated to one’s own life.

One of my extended family members is going through a rough time, as we all do on occasion. She came to us for some help. Since I naturally think and problem solve with a Lean mindset, I took this approach. Via guided questioning, we went through considering her problems, as I would with a practice problem.

True North

As with any Lean application, the first step is to define the ideal state: our ‘True North. If you were perfect, what would that look like? What areas of your life would you choose to define that perfection? What would be the focus areas? These might include such areas as spiritual ideals, physical ideals, financial ideals, relationship ideals, career ideals, etc. Pick four to six to work on at this time (or even just one!); choosing too many will be overwhelming and spread your work too thin. Create a True North statement in writing. Refer to this document often.

The Current State

Now that you have some conception of where you want to go, you need to honestly define your current state. Where are you right now in each of your focus areas? In an organization, this would be facilitated by going to the gemba with all of the stakeholders (line workers, supervisors, managers, etc) present, in order to observe what is really occurring in the Value Stream and, perhaps, drawing a Value Stream Map. Your gemba is deep inside you. It is your true self, warts and all. No preconceived ideas, no masks, no ego. What is the reality on your “shop floor?” Who are your stakeholders? Consider spouses, good friends, clergy, close colleagues, doctors, advisors. Write down your current situations.

Identify the Gaps.

At this point, you know where you want to be, and where you are in your focus areas. What are the differences or gaps? For example, you know you would like to be at some ideal state financially, and you know where you’re at currently. What is the difference between these two states? These are the problems you need to solve now. Write these down for each of the focus areas.

Root Cause Analysis (5 Whys)

Take some time to think about this step. Why are these gaps present? How did they come about? Why did this reason occur, and why did it happen? How did it happen? Ask enough times that you feel you have identified a root cause. This is important because, until the root cause is found and dealt with successfully, it will continue to be a problem. Notice I didn’t ask who was to blame. Try to concentrate on the systems, biases, prejudices, emotional needs, habits and the like. The idea is to deeply understand how this issue came about. It’s not because you are a bad person. We all are damaged in some way and have shortcomings,but how did these root causes contribute to your current state? Talking with your stakeholders may help.

Design Countermeasures

Now it is time to actively try to remedy the gaps: the problems. In each of your focus areas, what can you do to get even a little bit closer to your ideal state? Remember, though, your ideal state is perfection, and that is not realistic. There are always going to be gaps (problems), but with patience and persistence, you can get very close, greatly reduce your stress and frustration, and greatly increase your happiness, confidence and self-actualization.

Pick the low hanging fruit. Start with the easy stuff. Rack up some small successes that will then lead to greater momentum to tackle the bigger stuff. Focus on baby steps.

These countermeasures are experiments. After the trial period, evaluate the results. If they didn’t work out as planned, reflect on why and how, then tweak the experiment and try again. Try not to get disheartened. Lean is a journey. There will always be experiments to try.

If they do produce gains, then reflect on this, also. Why did this experiment work? What did you learn about the situation, about yourself. Can this same idea or principle be utilized in another aspect of yourself? Sustain this new you and rewrite your new current state. Congratulations!

5S

5S is one of the “tools” in the Lean system. It stands for Sort, Straighten, Shine, Systematize, and Sustain. It typically is used to reorganize a physical space, such as a surgery room, exam room drawer, office. It is used to decrease confusion, wasted time hunting down instruments or tools, and increase visual management.

Are there aspects of your life that could benefit from eliminating “garbage,” reorganizing, and/or prioritizing? What about faulty thought processes, biases, relationships, habits, wasted resources, beliefs?

Kaizen

Kaizen means continuous improvement. There is no set amount that is required, only that we try to be better tomorrow than we were today. There is no punishment if we are not successful on every attempt. We just try again. Again, baby steps. As stated above, Lean is a journey, it is a philosophy, it is a mindset. It is lifelong. The process of defining our current state, identifying gaps and experimenting will never end. But, success will come, if only one millimeter at a time.  “Patience, Grasshopper”!

Final Note

I am not speaking from any ivory tower. I struggle with all of this from time to time and have for most of my life. I, too, am on a journey; a work in progress. Veterinary medicine is not easy.  Veterinary practice management is even harder. I have started a practice and been a solo practitioner for over 30 years (for two of those years I owned and operated two practices), merged practices, worked for a corporation and three other employers. I have stayed awake many a night worrying about my business, my family, my health and my faith. I have experienced complete ‘burn out’ and come out the other end. My goal is to attempt to be better tomorrow than today. None of us are responsible for saving the world, but we are required to participate. Success, in my humble opinion, is to leave this world a little better for having lived here. A Lean mindset supports this effort.

Thanks for stopping by. Comments always welcome.

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.

5S

5S is part of the Lean approach to of “visual management,” as a way to show problems and irregularities, so they can be fixed quickly. As such, it is also an aspect of flow, standardized work and the elimination of waste. 5S deals with workplace organization, i.e. exam rooms, pharmacy, lab, surgery, or even the organization of email and information, etc. The workplace is organized to make work easier, clutter is removed, areas are cleaned, and the locations for supplies and movable equipment are labeled. A place for everything and everything in its place (once we figure out the right place!), and in the right amount. It requires the answering of two questions: (1) Do we have all that we need at the gemba, and (2) Do we need all that we have at the Gemba?

The five Ss stand for:

Sort (Seiri)
Go through the work area looking for any old, expired, irrelevant or broken items, and remove them. Throw them away or, at least, get them out of the way (if they are items that are used infrequently or non urgently). Do you really need to keep rabies certificates from 1987? Does anyone even know what a hemocytometer is, let alone still use it? Besides, the latex tubes disintegrated a decade ago!

Straighten (Seiton)
For everything else that remains, organize it. In the exam rooms, for instance, you try to make each exam room similar to the others so that there is continuity from one exam room to the other. Items used more frequently should be placed closer at hand to save time for staff and veterinarians, which can reduce delays for patients and increase office capacity and throughput.

Shine (Seiso)
Clean up the area and have a process for ongoing cleaning and sanitizing (as a form of standardized work). This minimizes contamination and infectious disease. The regular shine process is also the time to check equipment and perform timely maintenance. This keeps the hospital in a state that is a source of pride, with improved quality and safety

Systemize (Seiketsu)
Once the first 3Ss are done, we need to help make this an ongoing system, rather than a onetime activity. Ask if each of the drawers in cabinets, in each of the exam rooms, contain the same supplies and are they arranged in the same way? Systematizing helps prevent confusion and wasted time looking for items. This step provides the method to the madness. Label the drawers, cabinets and even the tops, so everyone knows what is supposed to be there and can easily see if it is not. It is similar to the woodworker who paints silhouettes of his hand tools on the wall to show where they belong, and to quickly, visually highlight when they might be missing.

Sustain (Shitsuke)
Again, 5S is not meant to be a one-time project. It should be an ongoing activity in the practice, to keep things organized, and to be continually improved. Management oversight, 5S audits, and continued improvement are the key to ongoing 5S success.
