Often associated with Six Sigma, few certification providers have created standalone Lean certifications for professionals and industries interested specifically in Lean and its broad toolkit.
In most cases, implementing Lean should precede Six Sigma, as Six Sigma helps reduce variation and achieve very high levels of performance, tolerating no more than 3.4 defects per million opportunities.
Imagine starting with Six Sigma when Lean has a big opportunity to literally clean the workplace and get rid of waste across processes. It would be non-justifiable!
We are used to seeing Lean Six Sigma certification levels represented by belt colors, such as Yellow, Green, and Black. This is less common when Lean is taught alone, without Six Sigma.
Indeed, ILSSI is currently the only accredited certification provider offering standalone Lean certifications with a belt-color system, with these certifications also available through its accredited partners.
In this article, we cover the best Lean Management certifications from different perspectives: certifications with belt colors, general Lean certifications, and certifications focused on specific Lean tools.
