OBJECTIVE
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
Participants are expected to be familiar with the material covered in the course ‘Statistics in Practice (SIP)’. No prior knowledge of SQC is required.
The course is aimed at people who work in the process industry, be it chemical or pharmaceutical, biological or purely physical. Whether you are responsible for the production process, quality control or a specific laboratory analysis, you will be able to immediately apply in your work what you learned in this course.
SET-UP
In this course theoretical aspects are alternated with hands-on exercises. All examples and exercises are based on chemical processes.
