How to be Certified in Lean Six Sigma

How to be Certified in Lean Six Sigma

Now that you know the numerous benefits and advantages of being certified in Lean Six Sigma, the next step is learning to be one.

  • Decide if you need the training - Most professionals enrol on Lean Six Sigma either because their organisation will adapt to Lean Six Sigma methodology and need the employees to transition, or they're already in project management, and want to be promoted. Some are beginners and want to start a career in project management. Regardless of the reason, you must ensure that getting certified aligns with your career goals.

  • Determine your belt level - Lean Six Sigma has different courses and belt levels. For beginners, it's best to start with a Yellow Belt certification. If you have the foundational knowledge, you can move to Green Belt, Black Belt, and Master Black Belt.

  • Enrol and attend a Lean Six Sigma training:Before enrolling on a course, you must check the certification body. There are several reputable certification providers for Lean Six Sigma, like CEPAS. Being approved by these awarding bodies ensures that your training meets global standards. After verifying, you can enrol on one of our courses here at e-Careers.

    We provide certifications for Yellow Belt, Green Belt and Black Belt. When you choose us,  you will earn one of the few Lean Six Sigma qualifications that meet the global ISO 18404 standard. Our training course includes comprehensive training materials, exams, and certifications, and you will also be registered on the CEPAS public register of Lean Six Sigma-certified professionals.

  • Participate in Practical Projects:Gain practical experience in real-world Lean Six Sigma projects. Application of the methodologies in a practical setting is often a requirement for certification.

  • Complete Training and Exam Requirements:Successfully complete the required training modules and pass the certification exam. The exam assesses your understanding of Lean Six Sigma principles and your ability to apply them.

  • Submit Project Work (if required):If your certification requires project completion, submit documentation and results for evaluation. This step ensures that you have successfully applied Lean Six Sigma methodologies in a practical scenario. However, our courses here at e-Careers don't require any project management work. The last step of your training course is passing your examinations.

  • Receive Certification: Upon successful completion of training, exams, and project requirements, you will receive your Lean Six Sigma certification. The certification may be in the form of a digital badge or a physical certificate.

    Remember that the specific steps and requirements may vary based on the certification body and the level of certification sought. It's essential to check the specific guidelines the chosen certification organisation provides and adhere to their requirements throughout the certification process.
