Lean Six Sigma Belt certification

How do we akt?

As a Lean Six Sigma Master Black Belt, we can train your employees on site.

The content of the standard certification is taught using examples from the organisation and/or production on site.

The following certification is possible:

  • Lean Six Sigma Yellow, Green Belt
  • Lean Six Sigma Black Belt
  • Lean Six Sigma Master Black Belt

In an initial consultation, we work with you to clarify your expectations of the individual certification steps. Following the initial consultation and a visit to the organisational unit concerned, you will receive a quotation from us for your employees’ certification.

If the client’s employees do not pass the examination, the certificate cannot be issued and the examination must be repeated (maximum of 2 repetitions).

Your benefits

  1. If unresolved problems from your organisation and/or production are used for the practice units and may be resolved during the activity, the company benefits immediately from the certification.
  2. Employees have easier access to the certification content during certification.

The certification is conducted in accordance with the requirements of the IASSC (International Association for Lean Six Sigma Certification www.iassc.org) and ends with an examination specified by the IASSC.
