“Lean six sigma” or “six sigma” certification?

You may see “lean six sigma” and “six sigma” certification being used interchangeably as you research which qualification is right for your next step.

What is the difference between “lean six sigma” and “six sigma”?

Lean and Six Sigma are two separate methodologies that originated in different places, at different times.

Lean is focused on eliminating waste from and streamlining a process. Six Sigma works to reduce errors and keep quality consistently high.

Both approaches work to improve processes and quality in different ways. When combined, they become a powerful transformational tool for any business.

As outlined in an excellent article by Grey Campus, the very nature of Lean and Six Sigma means that they can, and should be used together within a business. (source: Grey Campus)

For this reason, most well-rounded certification programmes in process improvement will incorporate both methodologies.

Some certifications focus almost exclusively on Six Sigma. However, to gain optimum benefit and a confidence to implement real change and improvement, we recommend choosing a course that includes at least some focus on Lean.

Our Tip:

Rather than going by the course name alone, we recommend taking a look through the course content outline.

Sometimes, a course may be titled "Six Sigma", but will also include useful modules on Lean.

Is six sigma certification hard to get?

The challenges with lean six sigma increase as you progress. This goes for learning about lean six sigma, getting certified, and using it in your work.

This is a good thing.

It’s fair to say that those who are drawn to process improvement like the challenge and reward of problem solving and making things work better.

You will find that achieving a yellow belt is not too challenging, working towards green belt needs more focus and effort, and black belt requires experience, skill, and effort.

The level of challenge grows alongside your confidence, experience, and capabilities.

Therefore, achieving your first Lean Six Sigma certification is a quicker, easier challenge than say, becoming Six Sigma Black Belt certified, which takes time and dedication.

How long does it take to get certified?

The time frame for achieving lean six sigma certification varies depending on which certification you choose, and differs between providers. We have used our certification timelines as an example here.

At yellow belt level, you will achieve your certification following a short exam on day 2 of training.

Certification timeframe for our Lean Six Sigma Green Belt is usually about 3 months (with a couple of additional months before you receive the physical certificate). You can read our 3 steps to green belt certification below.

Our black belt candidates usually achieve their certification within a 6 - 7 month window.
