The Yellow Belt level of certification is for the completion of a simpler improvement project. This level of application of improvement methodology often involves the use of Lean concepts and tools in the identification of waste (particularly cycle time). Simpler planning tools are used like the A3 format or the PDSA format. Likewise, foundational measurement and analysis techniques are used oriented to Lean thinking and understanding the degree of waste across a target value stream.
The Rapid Improvement course covers the various competencies assessed through the project. They deal with demonstration of planning, measurement, analysis capability and the capacity to facilitate the relevant workshop(s) and engagement with the people involved. Measurable improvement must be demonstrated at the end of the project.
