In today’s competitive professional landscape, certifications offer a powerful way to validate skills, increase marketability, and advance careers. Among the most sought-after credentials are Lean Six Sigma Green Belt certifications and various Project Management certifications, such as Project Management Professional (PMP®) or Certified Associate in Project Management (CAPM®). While these certifications may appear similar at first glance—both dealing with process improvement and project execution—they differ significantly in scope, methodology, and career applicability. Understanding these distinctions is key to selecting the right certification for your goals.
