Why Six Sigma Professionals Should Earn a PMP Certification
Which Certification Has More Value: PMP or Lean Six Sigma?
People who are unsure whether to pursue Project Management Professional (PMP)® certification or Lean Six Sigma (LSS) certification often ask, “which is better?” These two distinct methodologies are complementary, so framing the question in “Lean Six Sigma vs. PMP” terms may be misguided. Additionally, employers often list both certifications as job requirements, and many professionals hold dual certification. To determine which one is right for you or whether to pursue both of these high-value credentials, there are numerous factors to consider.
This article outlines the similarities and differences between the PMP and LSS certifications, provides guidelines for choosing between them, and discusses the benefits of dual certification for project management and LSS professionals.
Similarities Between LSS and PMP Certifications
- Help professionals improve process performance
- Employ a five-phase methodology
- Are globally recognized and in demand by employers
- Apply to various function areas across industries
- Help employees add value to their organization
- Expand career opportunities
- Lead to higher earnings potential
Differences Between LSS and PMP Certifications
LSS certification provides individuals with a problem-solving framework, drawing heavily on statistical analysis to reduce or eliminate waste, lower defects, and improve customer satisfaction. With LSS projects, the emphasis is on developing and implementing a process that ensures quality. The five phases of the Lean Six Sigma process are: Define, Measure, Analyze, Improve and Control.
PMP certification teaches individuals how to lead and direct a team, and use a set of processes to effectively plan, orchestrate and control complex projects. They learn how to gain buy-in, manage risk, and establish effective stakeholder communication, among other skills. With project management, the emphasis is on developing and implementing processes to ensure a project is successfully completed on time and on budget. The five phases of project management methodology are: Initiate, Plan, Launch, Monitor and Control, and Close.
Earning and Maintaining Certification
Lean Six Sigma is a trajectory. Individuals gain mastery by progressing through a hierarchy of certifications that includes Green Belt and Black Belt. These certifications have no expiration date, and no single organization administers LSS certification exams.
Individuals earn the PMP designation by passing the PMP exam, which is administered solely by the Project Management Institute (PMI)®. To take the exam, individuals must meet professional project management training and experience. To pass PMI’s rigorous PMP exam, individuals must demonstrate thorough knowledge of the Institute’s Project Management Body of Knowledge (PMBOK® Guide). The PMP certification process can take several years and the certification must be renewed every three years through professional development units.
How to Choose Between PMP Certification and LSS Certification
The right choice depends on your current role or the position you are seeking and your long-term career objectives. If you want to be a project manager, the PMP designation immediately validates your competence and commitment to serving in this role. At many companies, this credential is mandatory for project managers. Additionally, the 2018 PMI Salary Survey of 33,000 certification holders from 37 countries, showed that PMP certification holders earn 23% more than their peers without the credential.
Lean Six Sigma certification is essential for Individuals working in or pursuing quality assurance roles in industries, including manufacturing and finance, that are heavy users of Lean Six Sigma. As with PMP certification, LSS certification can expand your job opportunities and provide you with knowledge and skills that enable you to perform your job better. Additionally, your earnings potential increases with each level of LSS certification. PayScale reports that in the United States an operations manager with a Green Belt earns an average annual salary of $80,726 and a project manager with a Black Belt earns an average annual salary of $92,886.
Keep in mind, though, that choosing which credential to pursue often isn’t a Lean Six Sigma vs. PMP proposition. They complement each other, and many professionals choose to earn both.

- Improved hiring potential and eligibility for positions that require both credentials
- Competitive advantage for positions that require only one of these credentials
- Expanded professional networking opportunities through membership in PMI and organizations including the American Society for Quality (ASQ) and International Society of Six Sigma Professionals (ISSSP).
