Introduction
In spite of the fact that in the business field the TQM and ISO 9000 systems are considered to offer the same level of quality practices, there are several differences between their principles that place certification far below TQM.
The ISO 9000 set of international standards was created in 1987 with the objective of standardizing quality systems. They have become a pre-requisite in many companies to be a supplier for their industrial clients. In fact, this objective is the first discordant element with the TQM system, whose objective is to improve management through compliance with certain principles, but applying them in a flexible way according to company characteristics.
