Abstract
Qualität (vom lateinischen qualis = wie beschaffen) beschreibt die Güte, den Wert bzw die Beschaffenheit oder auch die Gesamtheit der charakteristischen Eigenschaften einer Sache oder Person. Die Beschaffenheit und die Unterscheidungsmerkmale einer Ware oder einer Dienstleistung in bezug auf ihre Vorzüge oder Mängel gegenüber anderen Waren oder Dienstleistungen sind dabei von besonderer Bedeutung. Diesem allgemeinsprachlichen Verständnis steht eine Definition der DIN ISO Norm 8402 gegenüber, die Qualität als "die Gesamtheit von Eigenschaften und Merkmalen eines Produktes oder einer Dienstleistung, die sich auf deren Eignung zur Erfüllung festgelegter oder vorausgesetzter Erfordernisse beziehen" beschreibt. Qualität ist also nicht ein abstraktes Gut, welches Dienstleistungen oder Produkten anhaftet. Vielmehr bezieht sich die Qualität eines Produktes oder einer Dienstleistung auf eine konkrete Situation oder Problemstellung, in deren Kontext die Qualität bestimmt wird. Diese Sichtweise auf Qualität, die zweckorientiert im Hinblick auf bestimmte, festgelegte Bedürfnisse ist, nennt man teleologisch. Qualität wird in beiden Definitionen als eine Größe formuliert, die sich aus bestimmten Kriterien zusammensetzt (Gesamtheit der charakteristischen Eigenschaften, Gesamtheit von Eigenschaften und Merkmalen) und für das entsprechende Produkt oder die Dienstleistung typisch sind. Es gibt also nicht die absolute Qualität, sondern immer nur eine zusammengesetzte Größe. Das bedeutet auch, dass Qualität keine binäre Größe ist, sondern dass zur Bewertung von Qualität eine kontinuierliche Skala notwendig ist. Möchte man die Qualität messen, so benötigt man also zumindest Ordinalskalen oder auch Intervallskalen.
