Dieses Buch ist ein Leitfaden zur Prozeß- und Produktveredelung durch den Gebrauch einfacher technischer Qualitätsverbesserungen und experimenteller Gestaltungsmethodik. Der Akzent liegt auf den Grundprinzipien, von der folgerichtigen experimentellen Annäherung bis hin zur Problemlösung, die auch stichhaltige statistische Analyse einschließen. Alle Techniken, die in diesem Buch vorgestellt werden, wurden bereits in der Industrie in den verschiedensten Bereichen von Personen mit unterschiedlichsten Grundvoraussetzungen angewandt.
Gerade für Personen, die mehr an der praktischen Durchführung von Experimenten interessiert sind, jedoch nicht zur theoretischen Statistik neigen, ist dieses Werk sehr nützlich.
Es ist ein ideales Buch für Studiengänge zur experimentellen Technik und ist auch für das Fernstudium geeignet.
