Process Variation and Capability Assessment
Competitive companies understand that satisfying customers' needs and running a successful operation requires a system that is dependable, predictable and consistent. Many of todays quality management philosophies, such as Six Sigma, focus on reducing variations and scrap. A modern view of quality defines it as the inverse of variability. Therefore, measuring variability and finding ways to reduce it is important for the success of a company. This article presents a Weibull analysis approach to modeling production data for a process in order to assess its deviation and capabilities. This approach augments the Six Sigma-type calculations, which typically rely on the normality assumption.

Reliability Importance Measures of Components in a Complex System - Identifying the 20% in the 80/20 Rule
When analyzing a systems reliability and availability, measuring the importance of components is often of significant value in prioritizing improvement efforts, performing trade-off analysis in system design or suggesting the most efficient way to operate and maintain a system. Focusing on the most problematic areas in the system results in the most significant gains. This article presents different ways for assessing the importance of non-repairable and repairable components within a system using BlockSim.
