WHY A SPECIFIC SQC COURSE?
Where SPC (Statistical Process Control) can be roughly defined as ‘control charting’, SQC (Statistical Quality Control) has a much broader meaning; it involves SPC, capability analysis as well as Measurement System Analysis (MSA).
However, the way SQC is being treated in most textbooks and courses doesn’t focus enough on the typical problems of complex processes, and very often standard methods are not directly applicable. Also the specificity of the measurement system has its implications on the statistics involved, and should be explicitly taken into account.
In this course modifications and extensions to classical SPC are being proposed.

COURSE SET-UP
In this two-day course theoretical aspects are alternated with practical exercises. All examples and exercises are based on chemical processes.
The book “Introduction to Statistical Quality Control” by Douglas C. Montgomery is strongly recommended as additional reference material.

COURSE OBJECTIVES
The goal of this course: to offer a thorough introduction to SQC, with emphasis on typical situations in the process industry: one-at-a-time sampling, short-run processes, batch processes, serial correlations (“drifts”) and complex measurements.

INTENDED AUDIENCE AND PRIOR KNOWLEDGE
This course addresses those who are at level with the material treated in 'Applied Statistics - A primer'
No prior knowledge of SQC is required.
