Monitoreo de no conformidades (defectos) por unidad. D. Capacidad del Proceso (Capítulo 6/7) Índices

This is the heart of the book. Students encounter Shewhart control charts ($\barX$ and $R$ charts, $S$ charts), CUSUM charts, and EWMA (Exponentially Weighted Moving Average) charts. The complexity here lies in knowing which chart to use, how to calculate control limits accurately, and how to interpret "out-of-control" signals.

Before delving into the solutions, one must understand the weight of the problem. Douglas Montgomery’s text is not merely a collection of formulas; it is a philosophy of continuous improvement. The book bridges the gap between theoretical statistics and the messy reality of the factory floor or the service industry.
