This edited volume is divided into two parts: Part I On-line Control covers fields like control charting, monitoring and surveillance as well as acceptance sampling. Part II Off-line Control is devoted to experimental design, process-capability analysis and data quality. It is based on the 11th International Workshop on Intelligent Statistical Quality Control, which took place in Sydney, Australia, August 20 - 23, 2013 and presents papers that were carefully selected by the scientific program committee, reviewed by its members, revised by the authors and, finally, adapted for this volume by the editors. The workshop was hosted by Professor Ross Sparks, CSIRO, Sydney, Australia and was jointly organized by Professors Sven Knoth, Wolfgang Schmid and Ross Sparks.
