Understanding Course Naming Variations

These variations reflect training delivery methods, not differences in certification level. Regardless of course title, certifications recorded in this directory are standardized under the Lean Sigma Corporation credential designations listed above.
The certification designation (CSSYB, CSSGB, CSSBB, CSSBB+, or CMBB) is the authoritative indicator of the credential earned.
