  • Today, the term reliability is part of our everyday language, especially when speaking about the functionality of a product. A very reliable product is a product that fulfils its function at all times and under all operating conditions. The technical definition for reliability differs only slightly by expanding this common definition by probability: reliability is the probability that a product does not fail under given functional und environmental conditions during a defined period of time (VDI guidelines 4001).
