What is the Lean-Six Sigma colored belt designation for project team members who contribute approximately 20% of their time to QI projects while delivering their normal job functions?

The designation that fits project team members contributing approximately 20% of their time to quality improvement (QI) projects while still performing their regular job functions is the Green Belt. In Lean-Six Sigma, Green Belts play a crucial role in projects by applying the methodologies to improve processes within their work area, all while maintaining their primary responsibilities.

Green Belts are trained to understand and implement Lean-Six Sigma tools and concepts, which allows them to work effectively on projects aimed at improving quality, reducing waste, and increasing efficiency. Their involvement in QI projects is typically part-time, often balancing it with their other job functions, which aligns with the specification of contributing about 20% of their time.

Other belt designations represent different levels of experience and commitment. For example, Yellow Belts usually have a basic understanding of Lean-Six Sigma principles but are not actively involved in project leadership or execution. Black Belts, on the other hand, devote a significant amount of time to QI projects and often lead project teams, requiring a higher level of expertise and commitment than what is described in this scenario. Blue Belt is not a standard designation within the Lean-Six Sigma framework, and thus is not applicable in this context.
