The Lean and Process Improvement Cluster focuses on applying continuous improvement principles to high-mix, low-volume aerospace environments without fighting compliance or complexity. It reframes lean as a systems discipline rather than a people problem, emphasizing layered process audits, mistake-proofing, setup reduction, and standardization where it actually works. The content avoids generic manufacturing advice and instead shows how improvement efforts must align with certification, variability, and execution evidence. This cluster helps teams improve performance while reinforcing trust in their processes.
