Direct observation – seeing for yourself – isn’t just a keystone of The Toyota Production System. It’s the underpinning of all of science. Secondhand information cannot substitute for being there, intently watching and listening, trying to understand on the spot what’s actually happening.
​

Before Galileo conducted his now-famous experiment to demonstrate the force of gravity, the prevailing world view of this experiment was that if a large and small ball were dropped together, the large ball would fall faster. This incorrect image of reality had been in place for over 1000 years before Galileo challenged it.  For promoting this revolutionary concept of direct observation, Galileo is often referred to today as the “father of science.” But in his own time, he was ostracized as a heretic because he challenged status quo thinking.

So, what’s that have to do with going to see the workplace today – and, in particular, management’s role when we “go see”? Several key points come to mind. First, to understand the physics of the situation, we need to observe for ourselves. Second, the observation should relate to a hypothesis. Galileo actually disproved the hypothesis that the heavy ball would fall faster, creating a new version of we call common sense. Today, every grade-schooler can tell you about that experiment. This represents the technical side of ‘go see’ that requires both critical thinking and an open mind.

But there is also an essential social side to direct observation, which is management’s most important contribution to improvement.  Galileo’s brilliance was squashed in his lifetime because, in effect, because he had no management support.  They didn’t go see, didn’t have an open mind, and above all were not scientists. As a result, it took another few hundred years for Galileo’s thinking to be accepted. Without management validation and support, brilliant ideas languish, and improvement stalls.

Those of you who have seen Toast Kaizen, a short video to demonstrate the power of Kaizen – small changes for the better – may also recollect that direct observation was needed to understand the toasting process before we could even talk about improvement.

As a starting point, remember. You have two roles when you go see. 

First, you’re a scientist, present with a critical but open mind. You go to the Gemba to learn. 

Second, you are there to help in whatever capacity you are able. And if you’re a top manager, you can help in ways to energize and accelerate your Lean transformation efforts that no one else in your organization can provide – removing roadblocks, providing resources and generally creating an environment that challenges employees but also gives them safety to experiment without reprisal. 

Here are a few specific tips for Gemba Walks:

For starters, tip one: if you haven’t been in the practice of visiting the workplace, be careful not to scare people. Particularly as you begin to visit the floor, get your first-line supervisors involved upfront so that they can explain to their employees that management is visiting the floor understand and help to remove the struggles that employees have with their jobs. There will still be concern on the floor when you first visit, but a least a little less than if you show up unannounced.  This also engages your first-line supervisors upfront, lessening their concerns as well. In fact, a little preparation on your part will you some background on problems and opportunities in a particular area that will make you more comfortable when you go see. Having time to reflect on these in advance of meeting with associates will make you a more informed listener.  We repeat - informed yes, but only for listening and observing. You need to listen and observe. Ask questions, yes, to understand, but don’t also answer them – even if you think you know the answer.

Please remember that in a traditional environment, employees wait to be told what they think. As a top manager in a Lean environment, your job is to change that paradigm. You’re not just going to the floor as a scientist; you are also the chief executive change agent. Once you change, it will be easier for your managers and supervisors to change also. 

Tip Two: Don’t intimidate your employees bring a large posse of managers to go see. This just complicates communication. Yes, you may also benefit from having other managers along with the top manager so that they can learn as well, but don’t make the group so large that participation is difficult.

Tip Three: There are just so many ways to insult and disrespect people – and the more elevated your position in the organization, the bigger the insult. Here’s a list of Don’t’s.  Bottom line? If you can’t handle the social part of going to see, then you’ll never get to the science part. Respect for people is one of the most basic principles of the Toyota Production System. If you can’t show respect, then expect nothing in return.

Don’t:
  • Point, Lean, Drink
  • Use your phone, eat, laugh in a way that could be perceived by anyone that you are laughing about others working
  • Argue, interrupt the team members workflow, make verbal judgments about what is bad or different about the worksite you are in (this includes safety practices, quality procedures)
  • Stand over people (like lurking or stalking), get in the way of the team members working path, stand with your back to the team members for an extended period of time
  • Waste time with questions that are long and hard for the group to understand
  • Violate any safety procedure the company has requested
  •  Carry on multiple conversations within a group, make comments that can be overheard and taken out of context, come to the worksite without some way of saying hello or introducing yourself
  • Take pictures or video, or use stopwatches in any way without being involved with members from their organization,
  • Snoop through their documentation at the worksite

Managers often are oblivious to the impact that their individual behaviors have on team members.   All of these “don’ts” can render your visits to Gemba worse than ineffective if you don’t avoid them. 

So okay, that’s the Law. Now here’s Gospel: the good news.  If you offer appropriate, supportive behaviors, these will be understood by employees as well. And the more senior your role, the more impactful these behaviors will be to everyone involved. If you are the top manager, you take the lead and then others will follow. You won’t see an overnight turnaround – but very soon your sincerity and passion will catch on. 

It’s critical to connect with your team members in a way that will enable the science part of the Gemba walk to be productive. 

Do:
  • Respectfully recognize each person with eye contact
  • Ask interested, authentic questions of the people available at the worksite
  • Seek to understand and find things to replicate at your organization
  • Be aware that your posture and body positioning is telling a story to others (ex. shaking your head in a negative way when looking underneath a roller conveyor, yawning)
  • Try to stay with a high level of alertness to things all around you (360 degrees is ideal)
  • Wear the appropriate PPE at all times, be aware of other visitors to the worksite (auditors, customers, video crew, etc.),
  • Thank people for their time, insight, advice or let them know how you will benefit from their gift of sharing time and experience
    ​
In many ways, the social part of the Gemba walk is harder than the go see science, because it requires a change in management behavior.  At GBMP we like to say that Lean transformation is 90% people and 10% technical and the journey never ends of course. This is always room for improvement. Easier, better faster and cheaper, as Shigeo Shingo said, is the order for improvement. When you go to the Gemba, your role is to empower employees to achieve these ends and then to provide resources they can’t muster themselves – or remove roadblocks in your system that hold them back. Does your system “make these problems ugly?” Does the environment favor reporting problems?  Are there policies or organizational problems the inadvertently stymie improvement efforts? Take notes. These problems are your homework.
​

You don’t go to Gemba to tell anyone how to do their job; you go to ask and understand what they need to do their job. You go to remove their struggles.  And you go to learn and deepen your understanding so that you can be a better manager.  Your Gemba walk may be only 30 minutes, but if you follow these guidelines it will enable your team members to create breakthrough improvement and keep your organization headed in a True North direction.

The fundamentality of True North to TPS (or Why You Should Care about True North)

1/13/2020

In the context of the Toyota Production System, True North has a very concrete and specific meaning, an ideal that transcends any particular business or occupation. True North is not for you to invent, but rather to understand in the context of your business. It will guide your business strategy, but it is not your strategy. And if you follow the True North principles, it will generate terrific business results. But to be clear True North is not a set of results either.  If you understand its meaning, then all of the other pieces of Toyota's system will make sense to you. And if you don't understand it, then the rest of their system won't make any sense to you at all. That's how important it is.

Consider this: At some point, each of us is either a customer or a supplier. We generally think of external customers as the customers, but every downstream process within your company is also a customer. External suppliers are also very important providers -- they're the outside factory that typically accounts for 80% of product cost and, like our employees, can have a really big impact on improvement if we only include them in our TPS efforts. (See Supplier Kaizen for how to do this.) Customers and suppliers are really two sides of the same coin. Like doctor-patient, clerk-customer, machining-assembly, distributor-end user -- we all rely on each other.

Customers and suppliers – internal and/or external - they are the Yin and the Yang of commerce. The customer wants perfect goods and services, and the supplier wants to provide that very same thing. To head in a True North direction, your business perspective must be win-win for the customer and the supplier. 

In any process we say that the customer is first, meaning suppliers need to understand value from the customers' standpoint. For example, as customers, we would ideally have perfect quality and instant delivery of products and services, with absolutely no waste. That's the ideal, and this is True North, independent of your industry or job function.

But in order to approach this ideal for the consumer, we need to do a much better job supporting and developing our providers. Management's commitments to developing this most valuable, creative resource are the other side of the coin.

So that's the big picture. Now, let's break it down into its parts looking at the Yin and Yang of each part.
We’ll start with perfect quality. As consumers, we expect this, and providers will naturally do their best work to deliver it if they in work an environment that supports them. It's just human nature. Who likes to produce defects? No one. When provider quality is not perfect, the customer’s process becomes unstable and unpredictable.
There are two roads that can be taken when defects occur in a process: The traditional response to defects -- a very costly one -- is inspection, sorting, rework or scrap. These words may vary between industries, but they never drive defects to zero. These responses also subject the providers to mindless tasks that don't fix problems but only sweep them under the rug.

On the other hand, in a True North environment, the providers, be they employees or external suppliers, will be challenged to perfect the process through problem-solving and kaizen rather than just inspecting out defects. In this scenario, the consumer is provided real value while the provider is developing his or her ability. Win-win. Providing meaningful work to employees and suppliers, and challenging them to solve problems, is management's first True North goal. This requires drawing a line in the sand for defects: No defect is ever passed to the next process. Quality at the source is essential.

When first considering the idea of never ever passing a defect to the next process, you may be thinking "OMG we'll never ship another product."  But if you refuse to sort and sift through bad material from suppliers, quality will improve. Are your team members spending more time on sorting and rework than production? If so, then you haven’t solved the problems. But if you identify and fix these problems on the spot, you’ll all be problem-solvers. You can start today!

Of course, managers worry about stopping production to fix problems, but they soon learn that this behavior not only increases productivity and quality but also develops the skills and passion of the providers. It's the manager's responsibility to create an environment in which employees not only know where to look for improvement but also feel safe and supported when they identify problems. That's True North too. If the providers feel that reporting problems will affect their personal well-being then the problems are compounded: First the problem is not reported, and second the problem festers with the provider.

What is the solution? Employees must be developed as problem-solvers. They need to be given a basic understanding of problem-solving methods to support their efforts. Employee development through learning and practice is True North too. And the same ideal holds when we're working with external suppliers too.

Here are a couple of more tenets of True North that will create an environment favorable to problem-solving and improvement. First, an explicit and credible promise from management that employees will not lose jobs as a result of participating in improvements is key. While no company can guarantee lifetime employment, we can provide assurances that downsizing is not a planned outcome of improvement. Articulating the opportunities of TPS is management's responsibility. Management must also commit to removing destructive physical and mental stress (also known as Muri) from work. Simply put, employees with fried brains will not make good problem-solvers. If we can't identify and remove stressors, then they become the silent killer of engagement and enthusiasm. If as True North indicates, our employees and suppliers are the most important resources for improvement, then we had best make Muri elimination a top priority too.
​
Imagine a flock of geese in migration. For them, the direction is clear and shared. They have, as W. Edwards Deming put it, "constancy of purpose." Leadership will change from time to time along the migration, but the direction – True North - remains constant. Good luck & happy new year!

Excellent observation shared by GBMP CI Manager Bob Elliott.  Mistakes are inevitable but remember, people aren't to blame. Processes are.
