Ensuring Consistent Quality: Effective Methods for Assessing Process Capability for Normal and Non-Normal Data

To ensure consistent production of products and services that meet customer specifications, companies must ensure their processes are capable.  

This webinar covers techniques for estimating process capability for both normal and non-normal data. The session first discusses pre-requisites for estimating process capability, such as establishing process stability. It then briefly describes distributions and presents methods for estimating ppm levels. The webinar also delves into the use and limitations of common process capability indices like Cpk and Ppk.

Inaccurate estimation of capability due to inappropriate methods for non-normal data can lead to over-optimistic results, making it crucial to use suitable techniques. The webinar discusses methods for testing normality and presents transformations and distribution fitting as effective approaches for assessing non-normal data. It also includes several examples to explain the methods in detail.

A considerable misunderstanding exists regarding methods for assessing process stability and capability.  As a result, many companies incur excessive risks of customer dissatisfaction, warranty, recalls, and litigation. This webinar covers proper methods (and prerequisites) for estimating process capability. Additionally, the shortcomings of popular process capability indices are exposed. Following the webinar, participants will be able to quickly adopt the methods presented to improve their quality management system and the use of supporting statistical methods. 

The webinar will provide methods for assessing and understanding Process Capability.  Participants should be able to immediately apply the methods presented in order to: 

• Understand pre-requisites for assessing process capability
