Why Lean Six Sigma Deployments Fail!
When I was 18, I bought a 1967 Ford Mustang with a 302 Motor. The motor needed to be rebuilt which was an expensive problem for an 18-year-old. I thought to myself “how hard can it be? It’s just metal parts and gaskets.” I decided that I could rebuild the engine on my own. I’m sure you can imagine how this turned out. After many failed attempts and allot of money wasted, I took it to an expert to have it rebuilt correctly.
This is similar to how most companies deploy continuous improvement methodologies like Lean Six Sigma. Leadership thinks “we are educated leaders … how hard can it be?”. Six months into their “deployment” when they have created a CI department (of one) led by a brand-new Green Belt (with no previous project experience) that has been tasked with finding and solving problems, they (and their stakeholders) are wondering “where my ROI?”.
This is what happens when you have no clue how to rebuild an engine, but you try anyways. You will most likely “Crash and Burn!”.
Does this mean that you need an external consulting firm to guide you? You would expect me to say “YES” because deployments are one of our core services. The answer is “NO” … you don’t need an external consulting firm to deploy Lean Six Sigma. What you do need is education on: 1.) How Not to do it! And 2.) How to do it correctly. I will however add a disclaimer; even the best instructions cannot replace experience. If you were having open-heart surgery, would you want a surgeon who has only read a book on performing open heart surgery, or the surgeon with years of experience performing successful open-heart surgeries.
Now, let’s talk about “How Not to Do It!”. Below are Five (5) Reasons Lean Six Sigma Deployments Fail!
Reason #1: Our Executives are Too Busy for an “Executive Training”
“Our executives are too busy for an “Executive Training” … They support the effort, so do we really need the training?”
I can’t tell you how many times I have heard this when discussing a Lean Six Sigma deployment proposal. This is the first clue that the company’s efforts will most likely fail.
My team has one key metric to gauge the success of a deployment and that metric is the engagement of the Company Leaders. The more the leaders are engaged, supportive and accountable the better the chance of a sustainable deployment.

Reason #2: Leadership wants to want to train a lone Belt to be the CI person (and single-handedly save the world!)”
We teach several public Green Belt and Black Belt courses every week throughout the globe. One question that we ask our students in the beginning of each class is: “How many of you were sent to this class and are expected to go back to your company and ‘save the world’”?
What I mean by this question is: how many of our students are expected to learn the tools and methodology of a Lean Six Sigma Green Belt and then go back to their company and single handedly improve processes. It amazes me that nine out of ten students raise their hand.
Expecting the Belt to single-handedly address and solve the company’s problems is like dressing them in wooden armor with a wooden sword and shield and then sending them out to fight the fire breathing dragon. It’s a suicide mission. This is another key reason.why Lean Six Sigma Deployments Fail!

The belt needs to have an infrastructure (or foundation) in place to create sustainable change in an organization.

Reason #3: Leadership expects the Belt to learn Lean Six Sigma and deploy it in their company
Expecting the New Green / Black Belt to Deploy Lean Six Sigma in your Organization is like Expecting the Plumber to Build your House. Your plumber is an expert at plumbing, which is an important part of the house but there is much more than plumbing involved when constructing a house.
In the same sense, when implementing Lean Six Sigma in an organization, you wouldn’t ask a Green Belt or Black Belt with little or no experience leading a Lean Six Sigma deployment. But, in most companies this is exactly what happens.

Reason #4: Leadership expects the Belt to be the “Company Problem Solver”
One of the worst ways a company can fail in their Continuous Improvement Efforts is to promote the Myth that “CI’s role is to Improve Processes.”
It baffles me that some companies expect their Belts to be the “Company Problem Solver”. They are expected to find (or be assigned) and resolve process problems.
This is not a sustainable way to improve a company because you have broken the 1st rule of change management; “the process owner (SME) shall improve their own process!”.
The Belt’s job is not to be the “Sage on the Stage” (the problem solver). Their job is to be the “Guide on the Side” (using tools to help the SME’s find the real solution). It is an amazing transformation when the SME’s see the “fix” to the process in the data (swim lane maps, VSM’s, Spaghetti Diagrams, Hypothesis Tests, etc.). When the SMEs are team to identify and implement the fix then the SMEs will take ownership of the new process.
From my experience, this is one of the main reasons why Lean Six Sigma Deployments Fail!

Reason #5: The Belt becomes “Leadership’s New Toy” reacting to the 1.) “Pains” that they presently feel and 2.) Leadership agenda
This is one of the quickest paths to failure of a Lean Six Sigma Deployment. Here is a scenario that I have seen in many different companies: An employee from the organization is sent to a Green Belt course to learn Lean Six Sigma. When they return, the word gets around that the company has a new “problem solver”. The Green Belt quickly gets assigned random projects that are 1.) reactions to “pains” that we are experiencing presently, or 2.) Leadership agenda. Leadership has no training on how to effectively identify Lean Six Sigma projects. The company’s idea of a project ranges from: moving equipment; project managing a facility expansion; to implementing a new ERP/MRP system. None of these are Lean Six Sigma DMAIC opportunities.
Because the organization has not built the Foundation for a Lean Six Sigma Deployment, they will send the Green Belt on “wild goose chases” that will have no sustainable effect on the profit on the company.
