Lean Six Sigma is focused more on eliminating unnecessary activities from processes. It improves process speed and reduces cost. Its process improvements are based on eliminating waste from the system.
Both approaches can be successfully applied, but deciding which system to utilize should depend on the company’s goals and objectives.
Differences in Certification Eligibilities and Examinations

The Lean Six Sigma and Six Sigma training and examinations are distinctly different. Lean Six Sigma assesses the individual’s knowledge and ability to apply Lean Six Sigma tools. The Six Sigma certification exam focuses on the individual’s ability to use to improve processes.
The Lean Six Sigma certification exam generally requires much more practice and theoretical knowledge. The Lean Six Sigma exam often covers topics far beyond traditional Six Sigma certification.
The Difference in Time Commitment
Six Sigma and Lean Six Sigma are commonly used by organizations to improve the speed and efficiency of their processes. The main difference between these two models lies in the time commitment required.
Six Sigma is typically a longer-term initiative. It generally lasts up to two years, unlike Lean Six Sigma. This is intended to deliver results faster, typically within six months to one year.
Lean Six Sigma is more suitable for organizations requiring short-term results. It offers faster cycle times, enabling organizations to achieve their goal quicker. In contrast, Six Sigma’s lengthier cycles may be more suitable for organizations that require long-term results and where there may be room for improved performance and growth.
Therefore, when selecting between Six Sigma and Lean Six Sigma, organizations should consider their organization’s need for short or long-term results.
