I Want to Be Like Benny

“Do not wait for leaders; do it alone, person to person.” ~Mother Teresa

As I mentioned last week, my Dad is now recovering in a superbly run stroke rehab hospital.

This particular hospital has many wonderful attributes. It’s clean, organized, and actually feels more like a country club than a place of healing.

But the thing that really makes me rest well at night is the memory of one person. His name is Benny.

Benny works as a health care aid which means he, and his fellow aids, wear many hats.

Now I won’t pretend to act as if I know what a heath care aid is supposed to do because honestly, I haven’t a clue.

But what I do know is Benny truly inspired me with the way he performs his job.

Why? Where shall I start?

He Makes People Smile

Benny, who is pictured above with my Dad, is the type of fellow who immediately elevates the mood of a room with his presence.

The patients gravitate to him and Benny knows how to make each of them smile.

For some he sings the first line of a song allowing the patient to finish it. For others he jokes about the “steak and lobster” dinner they are about to enjoy.

No matter what it takes… Benny makes people smile and feel better about where they are.

He’s Compassionate

Benny is also extremely compassionate.

The last night of my visit was very hard. There were so many emotions stirring inside of me. I was crying. My Dad was crying. My siblings were crying.

And as I left my Dad’s room and walked down the hall there was one person I sought out – Benny.

Being the ultimate professional, it didn’t take long for Benny to see how upset we all were.

Benny has this way of looking you in the eye with extreme compassion when needed. And while I never saw Benny cry… it did seem his eyes glistened a bit as if to say, I understand your pain.

My last words to Benny were to please check on my Dad in a few minutes and then I thanked him for all he’s doing for my father.  I left knowing my Dad was in great hands which in turn gave me an incredible amount of peace.

Benny is Good at His Job

With all of this said, there are obviously many technical aspects to Benny’s job. And, to be sure, Benny is great at this phase of the game as well.

While he is a friend to his patients he is also in charge. As such, things are done right and done well.

Be Like Benny

Listen, folks. I’ve met many powerful business leaders including CEO’s of multi-billion dollar companies. Sure these folks can inspire with their charisma and charm.  Earlier in my career it was people like this that inspired me.

Not anymore. Instead, it’s people like Benny that inspire me at this phase of my life.

You see, I want to make people smile like Benny. I want to be as compassionate as Benny. I want to be as good at my work as Benny is at his.

I’m not sure I ever will be… but, God willing, I’ll die trying. I welcome you to do the same.  If we all do this… the world will be a much better place.

Thank you Benny

Thank you for what you do, Benny. I, and I know I am speaking for my family, appreciate you more than you know.

Gettin’ Jiggy With It

I’ve been doing a tremendous amount of classroom training the last few weeks. As an aside, if you’re interested in having me or one of my colleagues conduct in person training (lean or six sigma) please contact us.

Anyhow, over the last 14 days I’ve taught more than 40 people everything from hypothesis testing to the different types of pull systems used during lean implementations.

The students have been fabulous and a true joy to teach… but that’s not the point of this article.

You see, while teaching these classes I was reminded of how important it is to just chill out and have some fun. Allow me to explain.

Teaching Stats is Boring

Teaching statistics to a bunch of Black Belts is not always exhilarating. There’s some math and, for some, that isn’t much fun.

Well, during one of the harder lessons on Advanced DOE (Response Surface Optimization) I decided to shake things up a bit… and by shake I really do mean shake.

Half way through this lesson we were transitioning into the teeth of the concept and I knew some students would be intimidated.

Getting’ Jiggy With It!

To counter this, I inserted a funny slide with the picture of a crazy dog dancing summarizing how we were going to take things to the next level. In other words we were about to “get jiggy with it!”

I also had Will Smith’s song “Getting’ Jiggy with It” automatically play when the dog picture appear. To add additional shock factor I asked one of my colleagues to come to the front of the room before the slide (and music) played.

Once he and I were in position I transitioned to the slide… as the music started to play we both started to dance like true fools for about 15 seconds.

My colleague attempted a form of the “sprinkler” and only the good Lord knows what my little dance moves should be called. As an aside, I’m the guy on the right in the picture above… and to protect the innocent I’ve blurred out my colleagues face so he doesn’t shoot me. Ha!

Total Engagement

But here’s the thing… once the class got over the shock of what was happening they exploded into applause. And I really mean exploded!

And most importantly… the class was totally engaged and ready to learn. They were having a tremendous amount of fun and things went far better than I ever expected with the teaching of Response Surface Designs.

The True Lesson

The true lesson for me was to never forget how powerful a little shock and extreme laughter can be.

If you are a consultant or trainer of any kind I strongly encourage you to stop taking yourself so seriously. You’re not a professor attempting to make people fall asleep. And chances are good that the material you’re presenting is pretty boring. Sorry, but it’s true.

So, don’t be afraid to shake things up a bit. And don’t be afraid to act like a fool for 15 seconds. It just might engage your students like never before!

Do you agree?

What do you think of this picture?

My family and I recently took a road trip.  During a stop at a restaurant I came across this sign in the restroom (click picture to enlarge it).

I’m curious to hear your thoughts on whether you think this is a weak or strong control.

LSS Academy Now on LinkedIn

I’m happy to announce that LSS Academy is now on LinkedIn.

We’ll obviously continue to roll strong here on the blog… but there seems to be something something special about LinkedIn when it comes to generating buzz about lean and six sigma.

So, I hope you’ll join the conversation over at the Lean Six Sigma Academy LinkedIn Group today!

There are many other outstanding LinkedIn Groups as well… just search for “lean” or “lean six sigma” and you’ll discover a lot of excellent conversation already in progress.

To Certify or Not…

Mark Graban wrote a relatively simple post a few days ago that has simply BLOWN up with comments.

Mark, if I may be so bold, doesn’t really believe in certifications… especially if the words six sigma are involved!

Me, well I do have certification in six sigma… and am proud of it as I had to work my butt off for it.  And, more importantly, my certification got me interviews for jobs I wouldn’t have ever gotten without the certification.

With this said, I  am always interested in what others – like Mark – have to say on the matter.

So, while I am all about comments here on LSS Academy I’d like to encourage you to visit the Lean Blog and continue the discussion there rather than here.  As of this post there are more than 40 comments!  So please head on over there and keep the discussion going LSS Academy readers!

If Lean Is So Great, Why Is Toyota Struggling?

Balaji, a reader of LSS Academy, recently sent me the following question/comment via email:

Toyota, GM, and Ford are experts in state of the art assembly technology and in implementing Lean and Six Sigma process improvement methods and so on. Then why have GM & Ford failed? Even Toyota closed its branch production units in Japan? Though I’m also one Lean Six Sigma Black Belt I too lost the confidence that Six Sigma or Lean or TPS can’t do anything in this recession period.

Regards,
Balaji.

Correcting Misconceptions

Before getting started, let me first say that I’ve done some research and don’t believe Toyota has closed any production units in Japan. If I am wrong here feel free to comment below with a correction.

Also, before the lean purists get too excited Toyota does not practice “six sigma” the same way companies like GE and Allied Signal do.

With all of this said, Toyota is still struggling these days just like many other companies.

The company is still deep in the red, logging a net loss of 77.82 billion yen (US$817 million) for the April-June quarter.

How can this be?

So the million dollar question is how did this happen? How could the mighty Toyota, the company that “changed the world” with their production and management system, lose money like this?

The Reality of Running a Business

Well, here’s my take on it.

No matter how amazing your production or management systems are or how well you respect people or how conscious you are of the environment… if no one is buying your product or service problems are coming.

You don’t need to be a CPA to figure this out… if your expenses are greater than your sales you’re in for some trouble.

And it goes without saying that people haven’t been buying many automobiles the past few quarters and no one, including Toyota, saw it coming. Perhaps they should have… but they didn’t.

Now, to be fair, Toyota has weathered this storm about as well as any automotive company SINCE they have an amazing production and management system… but they are not infallible. Far from it.

Rise Up Continuous Improvement Practitioners!

So does this mean lean and six sigma practitioners like Balaji (or you and me) should pack up ship and run for the hills until the orders start flooding in again?

Of course not.

Your company needs you now more than ever. Specifically, they need you to:

  • Attack the waste that is sucking operating income down the drain.
  • Find better ways to manage the inventory that is tying up much needed cash.
  • Reduce lead-times that will make you more competitive.
  • Partner with your sales and marketing team to see how you can apply lean and six sigma principles.
  • Stay positive while working to make things better EACH AND EVERY day even though you might feel like your boss is more focused on other things (like how to make payroll this week).

A “W” Recovery?

This market will eventually turn around. However, I’ve heard some economists claim that we might follow a “W” recovery pattern instead of the more common “V” recovery pattern we often see after recessions.

In other words, things could look better (like they seem to be now?) only to tank once more before the final recovery takes place.

But no matter how things recover one thing is for sure… the companies that work to become stronger during this recession by investing in continuous improvement will be the new winners of the post recession period. This I’m sure of.

What do you think?

Do you agree with me? Do you have any other thoughts on why lean exemplars like Toyota are losing money? Do you agree that investing in continuous improvement is more important than ever in these tough economic times?

Oh Snap! We Sent Bad Product to Our Customer: Fun with the Hypergeometric Distribution

If you enjoy statistics this is the perfect article for you! But even if hearing the words hypergeometric distribution makes you want to yack all over the floor at least give this article a quick skim as it could prove useful for you someday… especially if you ship a product or service to a customer!

The Scene

To help me with this article I’m going to make up a completely fabricated story.

Let’s say a producer of widgets (replace widgets with the product your company produces if you wish) recently shipped 1,000 units to their customer.

Let’s also say that, prior to shipping these units, the producer randomly inspected 100 widgets.

After inspection, the producer ships the 1,000 widgets to their customer, collects payment, and moves on to the next order.

The Angry Customer

A few weeks later the producer gets a phone call from their customer – who is less than pleased to say the least – explaining that they’ve discovered 4 defective widgets and they hadn’t even looked at all the widgets!

The customer goes on to say that they are sending all 1,000 widgets back and they are giving the producer 10 days to make things right.

Calling All Inspectors

Once the widgets arrive back in the plant a team quickly inspects all 1,000 widgets. Once they are complete they realize that 36 of the widgets were actually defective!

Identified Root Cause

Luckily, the root cause of the defective units was quickly identified and an immediate countermeasure was put into place ensuring this problem would never happen again.

How Did This Order Ever Ship?

The next question that was asked was how this order ever shipped. It was hypothesized that since 100 widgets were 100% inspected at least 1 of the 100 widgets should have been found to defective which would have forced a more thorough inspection of the entire lot.

Bring in the Black Belt

Not sure how to solve this problem the team asked their local Six Sigma Black Belt to help them determine the probability of catching at least 1 defective product while inspecting 100 units out of a lot of 1,000.

The Hypergeometric Distribution

After learning more about the situation the black belt decides to use the Hypergeometric Distribution, which Wikipedia so eloquently defines as a discrete probability distribution that describes the number of successes in a sequence of n draws from a finite population without replacement.

Here is how the black belt set things up in Minitab, which is the statistical software package they use.

In this example we are dealing with a finite population of 1,000 widgets so the “Population size” is 1,000.

Since we know, in this example, 36 widgets were defective and being defective is the “Event” in this case, the “Event count in the population” is 36.

Since the company sampled 100 widgets before shipping the lot, the “Sample size” is 100.

And since, for the Hypergeometric Distribution, X is the number of defective widgets we found in the sample of 100 widgets… X can range from 0 (we found no defective widgets) up to 36 (we found all defective widgets).

Now then, since the Black Belt wants to know the probability of finding at least 1 defective widget, they want to find the probability that X is greater than 0.

So, by using an “Input constant” of 0, they learn that the probability of having no defective widgets in this lot of 1,000 widgets is ~ 2% as shown above.

In other words, there is a 98% chance that at least 1 of the 36 defective widgets should have been detected during the inspection process.

The Conclusion

With this information, the team came to the conclusion that their inspection process was broken. There were three theories that needed to be investigated.

  1. The measurement system is not repeatable and/or reproducible
  2. The units were not inspected at all
  3. Defective units were allowed to pass

So, as is the case with many things related to continuous improvement, answering one question has created several more that need to be addressed.

What do you think?

What do you think of this analysis? Would you have done it another way? What about the conclusions of the team… can you think of another theory of why these widgets were sent to the customer?

Parenting and Lean Six Sigma

I am the father of 4 wonderfully perfect children. I love them more than words can describe and couldn’t imagine my life without them.

And, recently, I’ve been thinking about how much having children helps me to sharpen my lean and six sigma practitioner “saw.”

Of course this isn’t to say that those without kids can’t also sharpen their lean and six sigma saws… but we parents just might have a bit of an advantage if we leverage this gift we’ve been given.

So, with this said, here are some of the ways my children help me to be better at what I do.

Commitment

Raising children takes a tremendous amount of commitment and self sacrifice. No matter what… we know at least one of our kids will be hopping on our bed by 6:00 AM each and every morning.

Likewise, anyone serious about lean or six sigma knows how important it is to stay committed to excellence. In fact, every day you should ask yourself… have I left this place better than it was when I walked in this morning?

Patience

Ah yes, patience. It goes without saying that my kids often get on my nerves and really try my patience. Especially as they learn to ‘test boundaries.’ But I know this is part of growing up so I do my best to persevere.

Likewise, continuous improvement often comes much slower than many expect or desire. In other words, patience is most definitely required!

Continuous Learning

My wife home-schools our children and I often marvel at how much my oldest (6 years old) daughter has learned.

She, if you’ll allow a proud Dad to boast for a moment, is reading at around a 3rd grade level and can work my iPhone better than most adults I know!

But the thing I am most in love with is how hungry all of my children are to learn. I pray they never lose this.

Likewise, all lean and six sigma practitioners must continue to learn. There are many ways to go about this such as reading books, or blogs, or online training that never ends.

Long-term Thinking

As parents my wife and I are constantly thinking long term with respect to our children. We are doing our very best to form their faith while teaching them to be good citizens.

Likewise, many business owners and senior executives would do well to focus on the long term and not on how to simply make Wall Street happy this week.

Why, Why, Why, Why, Why

If there is one lean principle most kids have mastered by the age of 3 or 4 it’s how to ask why over and over.

Sadly most parents – myself included from time to time – often grow tired of hearing so many questions day in and day out which often times beats this amazing gift right out of our most important assets (our kids).

So, it goes without saying that if we grown-ups all learned – or remembered – how we used to ask why over and over… well, the world might just be a better place.

Let’s Hear from More Parents

If you’re a parent or spend a lot of time around children… what have I missed? Are there other things you’ve learned from your little one’s about continuous improvement or life in general?

The Critical Difference Between Defects and Defectives

Today I submit a quick, but extremely important post if you produce a product of any kind.

There are two different ways your product can be “bad.”

It’s defective

First, said product can be defective. This is to say something is wrong with it. It doesn’t work like it’s supposed to. It doesn’t look like it’s supposed to. The customer, who pays you good money, ain’t gonna be happy with said product.

It has multiple defects

Second, the aforementioned defective product might have multiple defects. This is to say there are many things ‘wrong’ with the product. It has 103 different scratches all over it, 14 surface mount components are not soldered correctly, and the text on the label is incorrect in 3 different places.

Manage the defects

In summary, it only takes one defect to create a defective product. But a single defective product can have a zillion defects.

What does this me to you, maker of said product? You need to stop focusing on how many defective units you produce… instead you should be laser focused on the number of defects you’ve created the past month.

Do you agree? Is this how you manage your business?
