How do you monitor those events that happen infrequently? You probably have a number of event types that happen a very few times in a period; for example, chemical spills, lost work accidents, excursions and the like. Because of the infrequency of these events, most Statistical Process Control charts do not handle these situations well. We can't effectively tell if we are improving or getting worse.

In this complimentary webinar, Guy March explores a couple of methods to effectively track rare events. Viewers of this webinar will:

In this complimentary webinar, Guy March looks at a few alternative charts that you might use in analyzing your processes. He disccuses the D and Q attribute charts as well as the EWMA and Cusum variable charts. Each of these charts has properties that can be helpful in the right circumstances.

With this discussion, you will understand:

This webinar explores the uses and misuses of the i, u and c charts in the Manufacturing and Service industries. An i chart is often used when a u or c chart would be more useful and effective. We present some basic theory of these charts as well as useful guidelines on choosing which chart to use.

This webinar looks at different charting solutions and examines different ways to better understand underlying issues. First Pass Yield is an important measure, whether we are talking about a process step pass, system pass, or Rolled throughput yield. We examine these and associated questions using Statit e-QC.

This webinar examines the use of Pareto and Paynter Chart Analysis. There are often many different aspects of a manufacturing process which can be improved, such as the number of defects, time allocation, cost savings, etc. Each of these aspects usually contain many smaller problems, making it difficult to determine how to go about solving the larger one. Using Statit's web-based application, we demonstrated the use of Pareto Charts and the ability of users to drill-down through their defect data to determine the root cause. We show how Paynter Charts are the next step in providing more detailed information about the Pareto and areas of opportunity for improvement.

In this webinar, we discuss the importance, application and calculation of several of the process indices such as Cpk and Ppk. Process capability indices help the quality professional and engineer to understand the relation of the voice of the customer to the in-control process. Understanding the principles and calculations behind the indices helps to properly apply them. Near normal distributions are required for standard process capability calculations, but often data are so heavily skewed that these calculations are ineffective. An analysis is also presented for non-normal distributions using Statit e-QC.

This webinar explores the concepts necessary to help you understand key concepts of rational subgrouping and help you decide what subgrouping scheme you should use for your control charts. There are many things to take into consideration in deciding what determines a subgroup and we will explore those of most importance. While this is a broad and deep topic, we will explore:

In this complimentary webinar, we discuss tampering and its effects. Tampering was responsible for the birth of SPC. We review that birth, as well as Deming’s view of tampering. Treating Common Cause variation as Special Cause is one of the quickest ways to throw a system into chaos. Understanding "What is tampering?" and "What is systemic change?" is important to the quality journey.
