How to Avoid Common Mistakes When Measuring Performance

Quality indices – Cpk, DPMO and first pass yield – are prevalent criteria for gauging the performance of products and processes. These indices, however, often are interpreted wrongly and used without taking into account the conditions of application.

Importance of Tolerance Design for Six Sigma Projects

Since defects can be defined as the failure of a product or a process to conform to requirements, the importance of designing those requirements or specifications is clear. The fact is, properly designed specifications can reduce DPMO.

Sigma Performance Levels – One to Six Sigma

When learning about Six Sigma, it may help to consider these charts, which detail how sigma level relates to defects per million opportunities (DPMO), and some real-world examples.

Six Sigma Aids in IT Employee Resource Planning

Effective resource planning is an important part of any process improvement program, including those in IT. Formalizing processes and developing measurement systems helps to determine the value of internal projects from a human capital perspective.

Six Sigma Opportunity Counting

The nature of Six Sigma opportunity counting and related metrics like DPMO and sigma levels can be confusing. This article contains ideas to help with opportunities and defect counting on your Six Sigma project.

Six Sigma Software Metrics, Part 4

This article is the last of four parts. It presents a discussion of opportunities for defects (OFD), defects per million opportunities (DPMO) and Sigma levels. When comparing implementations across companies, using the common language of DPMO and Sigma levels will assist in understanding benchmarking data.

Statistical Six Sigma Definition

The Six Sigma methodology is well rooted in statistics and statistical mathematics. Learn why six standard deviations is worthwhile for your organization to measure.

Using Weighted-DPMO to Calculate an Overall Sigma Level

An organization can have difficulty telling its overall sigma level because some of its critical processes are more important to its operations than others. One approach is to weight each of the critical processes when calculating overall sigma level.

Zero Defects: What Does It Achieve? What Does It Mean?

The use by business strategists of slogans such as zero defects to spur quality in an organization may lead to a de-emphasis of the tried-and-true tools and culture associated with successful continuous improvement programs such as Six Sigma.
