Lean Six Sigma Process

Six Sigma is a business management strategy originally developed by Motorola, USA in 1986. Six Sigma seeks to improve the quality of process outputs by identifying and removing the causes of defects (errors) and minimising variability in manufacturing and business processes.

It uses a set of quality management methods, including statistical methods, and creates a special infrastructure of people within the organization (e.g. "Black Belts" and "Green Belts") who are experts in these methods. Each Six Sigma project carried out within an organisation follows a defined sequence of steps and has quantified financial targets (cost reduction or profit increase).

Lean was originally used to describe the Toyota Production System, and is an approach used to maximise customer value whilst minimising waste. In simple terms this is creating more value for customers with fewer resources.

The Lean Six Sigma Green Belt certification is suitable for anyone looking to generate business improvements in areas such as: customer satisfaction, service delivery, cost control, process performance, & new product introduction. Lean Six Sigma is a process improvement methodology. Project and change management are ineffective without process management.

The course is designed for all business professionals from a wide variety of manufacturing or service / transactional environments. You will be involved in the deployment of Business Improvement or Green Belt projects as part of your job role / function.

A Six Sigma process is one in which 99.99966% of the products being manufactured are expected to be free of defects (3.4 defects per million).

Estimates place the quality levels of key processes in successful businesses today within the three - four sigma range. But an entire world operating at a four sigma level would incur:

  • At least 20,000 wrong drug prescriptions dispensed per year
  • Ninety-six crashes per 100,000 airline flights
  • Unsafe drinking water for almost one hour each month
  • No telephone service or television transmission for nearly ten minutes each week

A world operating at a six-sigma level would be much safer, with far fewer errors and far more happy customers.

The course covers both Lean and Six Sigma methodology, meaning that activities focused around the speed and quality of business processes are addressed.


You will gain your Lean Six Sigma Green Belt certification in only five days. You'll also get:

  • In-depth understanding of Six Sigma and Lean, and hands-on application of the Green Belt tool-kit applied to real-life problems in the industry
  • Insights on how to establish meaningful business metrics that align process performance with financial performance
  • A detailed view of Cycle Time Reduction, Process Variation and Risk Management
  • An actionable plan for identifying, scoping and chartering process improvement projects and selecting the right people to execute those projects
  • Build your personal abilities to support your organization by attaining Green Belt Certification, upon successful completion of this program.

Traditional Lean Six Sigma Black Belt training lasts 20 days. This normally includes a month between each module, meaning that it can take up to four months to complete. This is compared to ten days (Green + Black Belt) at Firebrand. Plus, our course contains case studies and exercises - it is not just theory.

What is a Green Belt?

  • Is trained in a subset of the Six Sigma and LEAN methodology and tools
  • Works on small scope business improvement projects, typically as part of their job role
  • Promotes and apply a common set of behaviors and practices to drive acceptance of Lean and Sigma concepts in the organization
  • Can be an effective team member on a Black Belt team

Other accelerated training providers rely heavily on lecture and independent self-testing and study.

Effective technical instruction must be highly varied and interactive to keep attention levels high, promote camaraderie and teamwork between the students and instructor, and solidify knowledge through hands-on learning.

Firebrand Training provides instruction to meet every learning need:

  • Intensive group instruction
  • One-on-one instruction attention
  • Hands-on labs
  • Lab partner and group exercises
  • Question and answer drills
  • Independent study


Frequently asked questions

Q. What is Lean Six Sigma?

A. Lean Six Sigma is a management philosophy that is used to transform organisations, helping them improve performance to become more effective and efficient. The Lean Six Sigma principles use tools from Lean Manufacturing and Six Sigma to improve quality quickly.

Q. What is the difference between Green Belt Six Sigma and Black Belt Six Sigma?

A. There are actually four levels of Lean Six Sigma Training - Yellow Belt, Green Belt, Black Belt and Champion:

  • Yellow Belts are trained in the basics of Lean Six Sigma, and can typically carry out performance improvements within their teams.
  • Green Belt Six Sigma professionals are trained and certified at a more advanced level, in the tools and approach of Lean Six Sigma. They tackle change within their business in addition to their other responsibilities.
  • A Black Belt is fluent in the use of the Lean Six Sigma approach and tools, often delivers major performance or efficiency transformation for a business. Typically, they are Change Leaders within the business.
  • The Champions are those that sponsor performance improvement projects. Typically, they are managers of processes and business areas that are trained to pinpoint where transformation / improvement needs to occur they remove barriers to the implementation of changes.

Q. Where should I train?

A. For Lean Six Sigma training, UK students prefer to study in a distraction-free environment. This helps them focus on learning and passing. Firebrand’s training courses are outside major cities.

Q. What is Sig Sixma?

A. Sig Sixma is a common mis-spelling for Six Sigma. It doesn't exist.
