An Overview Of Six Sigma: Everything You Need To Know

What exactly is Six Sigma? How can it benefit you? And what’s the DMAIC implementation process? While many are aware that Six Sigma is a fantastic manufacturing performance tool, the mechanics behind it remain largely unknown.

So we’re here to take you through everything you need to know about the method, and highlight the different training options available with The Manufacturing Institute. Read on to learn more.

What is Six Sigma?

Six Sigma can be defined as an approach that equips organisations with the tools required to better the capability of their business processes.


It was introduced back in the 1980s, when the telecommunications company Motorola was refining and improving its key production and organisational procedures. The method led to incredibly high levels of process capability, completely eradicating business and process costs and triggering a tremendous boost to its profitability.

Motorola coined the phrase ‘Six Sigma’ and since then, the approach has completely revolutionised how companies operate.

What is the DMAIC implementation process?

This process is what the Six Sigma approach usually follows. It’s an acronym: ‘define’, ‘measure’, ‘analyse’, ‘improve’ and ‘control’, like so:

  • Define – the problem and what exactly it should solve
  • Measure – the gap in performance and the process
  • Analyse – the process effectively so you can pinpoint the root cause
  • Improve – along the way, then measure the outcomes so you can learn from them
  • Control – the process to achieve higher performance (process capability)

How can Six Sigma benefit your business?

There are many advantages to applying the Six Sigma method, the main six being:

  1. Improving problem-solving capabilities by getting to the root cause of issues
  2. Reducing variation, leading to enhanced quality and productivity
  3. Linking up new and existing tools to a methodology that brings results
  4. Applying widely to industries, processes, products, and functions
  5. Broadening your set of tools, and learning how to choose the most appropriate ones for the job at hand
  6. Gaining invaluable knowledge about how your products or processes work – helping you make sustainable results and enable continuous improvement

What Six Sigma training is available?

At The Manufacturing Institute, we offer three Six Sigma training courses: Yellow Belt, Green Belt and Black Belt – each meant for practical application, allowing your business to bring about real change. As well as focussing on Six Sigma methods, you’ll also experience the benefits of learning a diverse range of techniques within lean and TPM.

Yellow Belt

This is for beginners – those looking to understand the language of Six Sigma, and needing to contribute to improvement projects as a team member or process owner. You’ll be taught an overview of the DMAIC methodology, plus discover the basic tools of variation reduction, problem solving and quality improvement.

Green Belt

The Six Sigma Green Belt Programme is designed for those seeking to lead victorious Six Sigma project teams. As well as a deeper exploration of the DMAIC methodology, it takes a look at an extensive variety of problem-solving strategies. What’s more, you’ll find out about applicable lean tools, along with critical factors for successful change management.

Black Belt

Through this course, delegates can achieve expert practitioner level status. It’s ideal if you want to take on a leading role in Six Sigma application and deployment. Through understanding a broad range of crucial and advanced Six Sigma tools and methods, you can lead critical and challenging improvement projects, as well as coach individuals and teams successfully so they can attain swift (and sustainable) outcomes.
