Variation is inherent in any process and cannot be completely eliminated. The goal of process improvement is to reduce the variation to an acceptable level. SPC (Statistical Process Control) and TQM (Total Quality Management) are different approaches to process improvement. Assignable causes of variation are factors that can be identified and eliminated to reduce variation, while common causes of variation are factors inherent in the process itself that cannot be eliminated but can be controlled to some extent.
