Introducing the Gemba Academy School of Six Sigma

Gemba Academy School of Six SigmaFor the past 6 months I, along with my Gemba Academy colleagues, have been extremely busy developing what we now call the Gemba Academy School of Six Sigma.

I’m obviously extremely biased… but I have to confess… I’m quite happy with the result.

The School of Six Sigma consists of 200+ videos covering topics ranging from Project Selection to Advanced Response Surface Design of Experiments.

We’ve also included several of our most popular, and critical, School of Lean courses such as 5S Workplace Productivity and Practical Problem Solving.

The Gemba Academy Difference

The thing I’m most excited about is the fact that both the School of Six Sigma & School of Lean follow the traditional Gemba Academy “site based” subscription model.

Traditionally, Six Sigma has been seen by some as an “elitist” methodology where only a few “chosen” people are selected to attend training.

Our sincere hope is that our site based subscriptions – which start at $1,295 for a one year subscription – will enable anyone interested in learning about Lean & Six Sigma the opportunity to do so.

For those interested, we’re also offering a certification option which will require both project work and the passing of an 80 question exam.

To be sure, we are not interested in becoming a certification mill where people essentially buy their certification.

Lean vs. Six Sigma

lean vs six sigmaAdditionally, another aspect of Continuous Improvement we hope to impact relates to the Lean vs. Six Sigma debate.

As many of you know, there are some “lean thinkers” who have less than kind things to say about six sigma.

And, to be sure, there are hard core “six sigma practitioners” who think lean is nothing more than laying tape on the ground and drawing value stream maps… which is obviously flawed logic.

True Knowledge

Socrates once said, “To know, is to know that you know nothing. That is the meaning of true knowledge.”

It’s with this same spirit that we sincerely hope to spread the good news that is Lean & Six Sigma to as many people around the world as possible.

And by doing so we hope to bridge the divide between lean and six sigma since, in the end, the two methodologies can work together in harmony.

Sneak Peak

Here’s a sneak peak at one of the videos from the DOE section of the course. If you’re reading this via email or RSS you may need to click through to the site.

How would you explain what Lean is to a 7-year-old?

Yesterday afternoon while driving home from a soccer game (and before I smashed into a Ford truck and obliterated the right side of my little Toyota… but that’s another story) my 7-year-old daughter (the swimmer and stud soccer player) asked me a great question, “Daddy, what do you REALLY teach people in Gemba Academy videos?


Now, to put this into perspective, my children know all about Gemba Academy and also understand many aspects of what lean is about.

This particular daughter even stars in our Gemba Academy Kaizen Overview video (she suggests moving the silverware tray closer to the dishwasher) at the 7:01 minute mark.

So, with this said, I knew I couldn’t offer a basic answer. So I paused. I pondered. What could I say to my 7-year-old daughter who already has some knowledge of what lean is about?

After a few moments… I replied, “Daddy tries to teach people how to work faster and make less mistakes. And, most importantly, we also try to teach people to be nice and respect each other… that way everyone can do their very best.”

As with anything related to continuous improvement I felt like my answer could have, and should have, been better.

What would you have said?

So, how would you have answered?  How would you explain what lean and six sigma and continuous improvement in general is all about to a 7-year-old?

5 Critical Control Chart Characteristics You May Not Be Aware Of

No matter if you call yourself a “lean practitioner” or “six sigma practitioner” or some combination of the two… one “tool” you should have a deep understanding of is the control chart.

I’ve written about control charts before so if you’re not familiar with what they are I’d suggest you check these articles out before pressing on with this article.

With this said, what I’ve discovered is that there are a few “details” related to control charts that many lean and six sigma practitioners aren’t aware of.

As such, I’d like to discuss 5 of these details in this article.

1. Collect 100 Data Points Before Calculating Control Limits

First, the “power” of any statistical test is directly related to sample size. The greater the sample size the greater the statistical power.

So, in order to ensure your control limits – which are calculated at +/- 3 Sample Standard Deviations from the mean – you should collect at least 100 data points.

If you don’t have at least 100 data points you can still calculate control limits but you should consider the results preliminary.

2. Study MR Chart Before I Chart

Next, when working with the I-MR or Xbar-R Charts we should always study and interpret the MR and R Charts before the I or Xbar Charts.

The reason this is so critical is because both the I and Xbar Control Limits assume the variability in the process is in statistical control.

So, even though the MR and R charts are shown below the I and Xbar charts we need to look at them first.

Furthermore, if we see any special cause variation in the MR and R charts we should seek to understand and counter the root cause of that variation before we take any action on the I and Xbar charts.

3. Start with Special Causes Tests 1, 2, and 7

Most Statistical Software packages, such as Minitab, allow you to test for 8 different types of special causes.

These tests were originally developed by Walter Shewhart and are sometimes referred to as the Western Electric Rules.

As it turns out, the statisticians at Minitab have done extensive testing and discovered that tests 1, 2, and 7 are the most useful for evaluating the stability of the Individuals and Xbar charts.

  • Test 1 checks to see if any 1 point is greater than 3 standard deviations from the mean.
  • Test 2 checks to see if there are at least 9 points in a row on the same side of the mean.
  • Test 7 checks to see if there are 15 points in a row within 1 standard deviation of the mean.

Of course you’re definitely free to use any of these 8 tests but, as a starting point, we’d encourage you to at least start with these 3.

4. Rational Subgroups Rock

Next, while the I-MR Chart is extremely powerful it is limited since each data point is created from a sample size of 1.

So, if we’re able to collect more than one sample we should since doing this will allow us to minimize any noise, for lack of a better word, within each subgroup while maximizing our ability to spot any signals, or special causes, between subgroups.

And this is where Rational Subgroups come in.

Formally defined, a Rational Subgroup is one in which multiple samples are collected so that the chance for variation due to special causes occurring within a subgroup is minimized, while the chance for identifying special cause variation between subgroups is maximized.

5. Choose the Correct “Variation” Chart When Using Rational Subgroups

Finally, if we’re able to collect data in Rational Subgroups the “variation chart” we choose depends on the size of the subgroups we collect.

  • Xbar-R Chart: We should use the Xbar-R (Range) Chart when our Rational Subgroups are less than 8 but greater than 1.
  • Xbar-S Chart: We should use the Xbar-S (Standard Deviation) Chart when our Rational Subgroups are greater than 8.

Now, since the Xbar-S chart uses the Standard Deviation it is more powerful than the Xbar-R chart which simply uses the Range.

Process Improvement and Rock & Roll

In 1967 Eric Clapton bought a ten-year-old Fender Stratocaster in London for £150. He nicknamed it “Brownie.”

3 years later Brownie was used to record “Leyla”. Even if you hate Rock and Roll you will have heard “Leyla.”

At the close of the 20th century “Brownie” was sold at auction by Christies in New York for $450,000. That is a lot of money for a guitar, particularly a rather old and beaten up guitar, even if it did have a bucket full of provenance.

What’s so special about the Stratocaster?

When most people hear the words “electric guitar” the first name that flashes through their minds is Fender Stratocaster. It is to rock and roll what Stradivarius is to classical music. Buddy Holly, Jimi Hendrix, Eric Clapton and Pete Townshend all played them.

Why did they all play the Stratocaster?

The guitar was developed Leo Fender after the Second World War. Leo wasn’t a guitarist, but he realised that the way to make a great guitar was to listen to guitarists and understand what they wanted.

  • The Stratocaster has a curved body so it is comfortable to play and doesn’t dig into the musician’s ribs.
  • The Stratocaster’s electric chord plugs into the front of the guitar, not the bottom so it is easy to connect to an amp.
  • The Stratocaster has 6 tuning pegs in line on the head stock rather than three on the top and three on the bottom, making it easy to tune.

But Leo didn’t just focus on the needs of the guitarist; the Stratocaster also has a modular design so it is easy for people to repair. Given the efforts Leo went to, to design the world’s most user-friendly guitar, it is hardly surprising that it went on to become a huge commercial success and a rock and roll legend.

“My first wife said, ‘It’s either that guitar (Strat) or me’, you know – and I give you three guesses which one went” ~ Jeff Beck

What can Leo Fender teach you?

The Stratocaster works because Leo listened to his customers and repairers problems and then solved them. He made it easy for them.

Do you design your processes with the same focus, giving customers what they want and making things easy? If you don’t, what could you change?

4 Cloud Based Tools That Have Dramatically Increased my Personal Productivity

As a business owner, husband, and father of 5 amazing children time is not something I have a lot of.

As such, being able to stay focused and productive is extremely important. A few months ago I realized I was not being as effective as I needed to be.

It wasn’t because of a lack of effort… I was working very hard. But there were certain things really holding me back.

So, after some personal hansei, I made some changes that I’d like to share in this article.  Oh, and as an aside, there are no affiliate links in this article.


The first change I made centered around better managing my daily tasks.

To do this, I started to use a free web based tool called KanbanFlow.

KanbanFlow allows you to keep track of tasks you need to do, plan to work on today, and are currently working on.

The Pomodoro Technique

There is another tool built into the KanbanFlow site centered around something called the Pomodoro technique for time management.

The Pomodoro technique promotes working with full focus for 25 minutes before taking a short break. Then work another 25 minutes followed by another break.

The big breakthrough for me was a simple one. During a Pomodoro cycle (which I am in now) I turn off email and any other application that may distract me.

Once 25 minutes is up (man it goes fast when you’re really focused) I accept the break and check email and tend to any urgent matter that may have come up. I also allow myself to sneak a peak at some of my favorite bloggers, or maybe check out my Facebook page, or read about my beloved Texas Rangers.

But, once the 5 minutes is up I do my very best to close everything back down while beginning a new Pomodoro cycle.

I’ve not perfected this and still need more discipline but I’m getting better.


At Gemba Academy we have LOTS of projects going on.

We’re working on things such as the launch of a formal School of Six Sigma, redesigning our website, and even experimenting with subtitles in Hebrew, Chinese, and Arabic!

Historically, we’ve done OK with project management by email communication and using things like Dropbox to collaborate and share files.

But, as of a few months ago, we officially hit a point where we just had too much to manage.

Enter Basecamp by the guys over at 37 Signals.

Basecamp is cloud based project management website that allows users to keep track of projects, assign tasks, and have discussions with team members.

With Basecamp, there is no need to “discuss” things via email… it can all be done in Basecamp allowing you to revisit a discussion you had 3 weeks ago quickly and easily.

I love, love, love Basecamp and can’t imagine how we ever got anything done without it.


Another cloud-based tool, also produced by 37 Signals, we just started to experiment with is called Highrise.

Highrise is a “simple CRM” tool that allows us to keep better track of customers we talk to and need to follow back up with.

We have used some other CRM tools in the past that were far more complex than they needed to be.

The power of Highrise and Basecamp is in their simplicity. They allow you to do the things you need to do and nothing more.

Organization & Focus

Really, when I step back to think about it, the theme of all the tools I’ve mentioned is is organization and focus.

By staying more organized I, and my Gemba Academy team members, are better able to focus. And by staying focused, we’re able to stay better organized!

So, hopefully this article has given you some ideas on how to improve your own personal productivity.

What Tips do you Have?

Since I’m always on the look out for better ways of working I’d love to hear your advice on how you stay organized and focused.

What tips and tricks do you use to manage your work?

A Factory of One

If you missed our most recent webinar called “A Factory of One you can watch a replay of it here.

It was excellent and I highly recommend you take the time to check it out.

It’s free to view until May 15, 2012.  After that it will only be available to subscribers of Gemba Academy’s Complete Lean Package.

You can watch the entire, hour long, webinar by clicking here.

Here is a description of the webinar.

Most people spend all their time applying lean tools to external processes and systems. But what about the fundamental machine of production: you? How can you reap the benefits from applying lean concepts to your own work?

Indeed, you can apply lean principles and tools such as visual management, flow, pull, 5S, and kaizen to your individual work to improve efficiency, reduce waste, and link yourself ever more closely to customer value. While it’s true that applying lean at the individual level won’t lead to an overnight revolution in organizational performance, it can lead to success stories that make you more effective, and can get your leadership to sit up and pay attention.

Dan Markovitz will share specific strategies from his new book, A Factory of One, that will help you use lean principles to make yourself and your teams more effective.

I second Dan in saying this may be the best 11 minutes of your day.  If you want to be inspired – and smile – watch this video (click through to site if you’re reading via email or RSS).  Really, folks.  Please watch this.  All of it.

Webinar Replay: Using SPC to Make Better Management Decisions

Update: This webinar can now only be seen by subscribers to the Complete Lean Package.

In this pre-recorded webinar, Mark Graban, author of Lean Hospitals and the upcoming book Healthcare Kaizen, showed how simple statistical process control (SPC) methods can be used by managers and leaders to make better decisions about their businesses.

Using examples from manufacturing, healthcare, and services industries, Mark illustrated the basic SPC rules and explained how to create and interpret a control chart, allowing you to spot statistically valid trends and avoid overreacting to common cause variation in your performance measures.

Click the thumbnail below to watch the webinar, which includes Q&A at the end.

Perseverance & PDCA

“Let us run with perseverance the race that is set before us” (Hebrews 12:1).

The ability to persevere through the tough times we experience as lean and six sigma practitioners is extremely important.

In fact, the ability to persevere through the tough times we experience as human beings is also important.

But, unfortunately, perseverance alone isn’t eough.

Not Enough

You see, in order to find success at work or home we must also continuously turn the PDCA (Plan, Do, Check, Act) wheel.

  • We must seek to deeply understand the problem or problems.
  • We must have the courage to relentlessly attack these problems knowing full well many of our countermeasures won’t work.
  • And once we discover a successful countermeasure we must seek to understand why it worked.

Definition of Insanity

Put another way… perseverance without PDCA is similar to the definition of insanity whereby one tries the same thing over and over expecting different results.  Not only is this a painful way to live our lives… it will indeed drive a person mad!

What do you think?

Do you agree with my thinking here?  Can perseverance succeed without some form of problem solving?

And what about PDCA without perseverance… can that work?  What do you think?
