Introduction: What is a Lean Six Sigma Yellow Belt?
The Lean Six Sigma Yellow Belt is the first step for those looking to contribute more actively to process improvement projects. It goes beyond basic awareness and equips professionals with practical skills to participate in improvement initiatives and support Green or Black Belt leaders.
Yellow Belts are trained to understand Lean and Six Sigma principles, assist with data collection, and contribute to identifying waste and inefficiencies in daily operations. They’re the frontline problem solvers who help embed continuous improvement into the organization’s culture.

Yellow Belt certification is ideal for:
- Team members participating in Lean Six Sigma projects
- Frontline staff or supervisors seeking structured problem-solving skills
- Analysts, coordinators, or quality reps who want to contribute to data gathering and process analysis
- Professionals moving toward a Green Belt or higher certification
What Does a Yellow Belt Learn?
The Yellow Belt curriculum offers foundational but actionable content, including:
- Key Lean principles (value, waste, flow)
- Core Six Sigma concepts (defects, variation, process capability)
- The basics of the DMAIC cycle
- Introduction to problem-solving tools like 5 Whys, SIPOC, and Fishbone Diagram
- Process mapping and simple data analysis

- Participating in problem-solving workshops (Kaizen events)
- Assisting in root cause analysis and data collection
- Identifying inefficiencies and potential improvement opportunities
- Helping drive local process improvements
- Supporting cultural transformation by promoting structured thinking
