Lean Six Sigma is a powerful methodology for process improvement, and earning a certification can significantly boost your career prospects. But with multiple certification bodies offering programs, selecting the right one can be confusing. This article explores the key differences between three leading organizations: American Society for Quality (ASQ), International Association for Six Sigma Certification (IASSC), and Council for Six Sigma Certification (CSSC).
Body of Knowledge (BOK):
While all three bodies emphasize the core DMAIC (Define, Measure, Analyze, Improve, Control) principles, some variations exist. ASQ delves deeper into areas like Enterprise-Wide Deployment (EWD) and Design for Six Sigma (DFSS), which might be less prominent in IASSC certifications.
Certification Requirements:
Project experience is a key differentiator. ASQ mandates project completion and submission of an affidavit for Green Belt and Black Belt certifications. IASSC and CSSC focus solely on exam knowledge. Exam formats also differ. ASQ leans towards application-based formats, testing your ability to solve problems using Lean Six Sigma tools. IASSC offers a mix of theory and application with proctored online exams requiring a webcam. CSSC stands out with open-book exams, allowing reference materials during testing.
Weighing the Advantages and Disadvantages:
ASQ:
- Pros: Industry-respected, project focus promotes practical application, comprehensive BOK.
- Cons: More challenging exams with a project requirement, potentially higher cost due to project work.
IASSC:
- Pros: Convenient online exams, no project requirement, potentially lower cost.
- Cons: Less emphasis on practical application, may not hold the same weight as ASQ in some sectors.
CSSC:
- Pros: Open-book exams for flexibility, potentially lower cost due to no project requirement.
- Cons: Less widely recognized compared to ASQ and IASSC, open-book format might be seen as less rigorous.
Finding the Perfect Fit:
Consider these factors when making your choice:
- Career Goals: If global recognition is paramount, ASQ might be the preferred route.
- Learning Style: Those who learn best by applying concepts might favor ASQ’s project-focused approach.
- Budget and Time Constraints: IASSC and CSSC could be faster and potentially cheaper options.
- Company Requirements: Some employers may have specific certification preferences.
Remember, all three bodies offer a valuable foundation in Lean Six Sigma. Research industry trends and your individual needs to select the path that best propels your career forward.
