The Performance Visibility cluster translates execution data into outcomes leadership actually cares about. It focuses on OEE, nonproductive time, downtime, and shift-to-shift variance, with an emphasis on high-mix, low-volume aerospace environments. The content clearly distinguishes meaningful metrics from vanity KPIs and explains how to calculate, interpret, and act on performance data. The goal is to help teams move from anecdotal explanations to evidence-based improvement tied directly to execution reality.
