Lean Gold case studies
Lean Gold · Put your knowledge to work in context.
Lean Gold is a professional credential in lean thinking and practice. Candidates typically include improvement specialists, operations and quality professionals, team leaders, and managers who want evidence of applied lean competence. Our independent study page mirrors the five equally weighted domains of the exam blueprint: lean principles and core concepts; value stream mapping and process analysis; waste identification and elimination; continuous improvement tools and methods; and lean deployment, leadership, and culture. Each domain carries 20 percent of the content, so no single topic can be skipped. The Lean Gold case studies are 5 cases and about 2,264 words.
