However, with increasingly complex machines and different sources of information, this is often a challenge. Products have become so complex that it is almost impossible to know all the machines and equipment.
Information on spare parts as well as the corresponding technical documentation for the individual machines and equipment are often available in different systems with varying quality and detail. To find the information they need, service technicians must know where to look and according to what criteria (e.g. keyword search in system A, inventory number in system B, part number in system C).
Internationally operating companies also face the challenge of ensuring consistent service quality all over the world. This is not always easy if there is no subsidiary in far-away countries.
