A pivotal role in continuous improvement of processes

Any organisation that strives for the highest quality, best delivery times and the lowest operational costs, has many professionals who dedicate time to process improvement within their respective units. These professionals are often certified Green Belts. They are involved in optimising daily operations and are often pivotal in creating the required change of mindset to an improvement culture.

Green Belts are ambitious and they can combine their Lean Six Sigma knowledge with their experience to allow their organisation to excel. For these reasons, a Green Belt course also greatly contributes to your career prospects.

Competencies for key personnel and their organizations in relation to Six Sigma and Lean implementation

Our courses follow this standard and adhere to the competencies described therein.

With its origins dating back to the 80’s, Lean Six Sigma is truly a well proven and globally recognised methodology in process improvement.

Nevertheless, there was often some ambiguity surrounding the qualifications in Six Sigma, Lean and Lean Six Sigma.

For example, if an organisation advertised for a Lean Six Sigma Black Belt, how could they be sure of the level of ability of a ‘Black Belt’? If a supplier said it had deployed Six Sigma or Lean, how could a customer be sure of their real abilities?

It is exactly for this reason ‘The International Organization for Standardization’ (ISO) defined a universal standard for Lean Six Sigma in ISO 18404.

This International Standard for Lean Six Sigma sets out to clarify the required competencies for personnel and organisations in Six Sigma, Lean and ‘Lean & Six Sigma’. In doing so, it has created clarity what third parties can to expect Lean Six Sigma professionals.

As our courses adhere to this international standard, the company looking for a Black Belt in the example above, can now be sure what competencies to expect from a Lean Six Sigma Black  Belt  certified by The Lean Six Sigma Company.

The Lean Six Sigma Company courses adhere to the ISO18404 standard which defines the competencies for the following Lean Six Sigma professionals:

  • Lean Practitioner

  • Lean Leader

  • Lean Expert

  • Lean Six Sigma Green Belt

  • Lean Six Sigma Black Belt

  • Lean Six Sigma Master Black Belt

Our certification criteria are directly derived from the ISO standard. Participants who completed the course, fullfill internationally recognised and objective requirements (ISO18404), which may be expected from Lean Six Sigma professionals.

Lean Six Sigma in your company

Although Lean Six Sigma is best known as a project-based improvement structure, it is much broader than that. Lean Six Sigma is an established philosophy, an organisational and improvement structure as well as a set of tools. Using this perspective Lean Six Sigma addresses organisational issues with respect to competitiveness, cost reduction and customer satisfaction. 

Depending on your ambition, Lean Six Sigma can be implemented in phases. Every organisation is unique, without a common blueprint that universally applies. Together with you, The Lean Six Sigma Company will develop a plan of action tailored to your organisation.
