The simple setting of goals does not make improvement happen.

An IEE value chain describes at a high-level what the organization does and the measurement of each function relative to a quality, cost and time assessment.

The following presents an alternative to Cp, Cpk, Pp, Ppk process capability indices.

For regions of stability, process capability indices can be used to describe how the process is performing relative to specification limits.

The question that one might ask is, "which control charting technique is most appropriate?" My response to this question is, it depends on how you categorize the source of variability relative to common and special causes.

In this blog and the next few blogs, I will expand upon the 30,000-foot-level methodology.

A test that samples and makes process statements from a 30,000-foot-level metric vantage point can provide more insight with less test effort than AQL testing.

If AQL testing is commonplace in an organization, consider viewing the AQL’s department activity as a process where input to the process is various types of batches that enter this process.

Sometimes we might be wasting too many resources attempting to answer the wrong question with much accuracy, or to the third decimal place.
