Maintenance is the first step to quality assurance of a producing company. QA element 4.9 (process control) of DIN/ISO 9001 basically mainly describes requirements to the maintenance. It is the first-mentioned QA element of the supplier's operative actions.

Goals exceeding DIN/ISO are based on the merging of TQM (Total Quality Management) with TPM (Total Productive Maintenance) and therefore make completely new demands on maintenance systems. The module iQ-INST implements these demands.


The concept of the iQ-INST module is based on three fundamental units. The first unit are monitoring installations that identify problems with devices and thus initiate maintenance demands that aim at identifying necessary improvements. One essential element of the monitoring is the so-called shift book where the operators of devices can enter many incidents and document the initiated actions. The demands themselves are basis of the second fundamental unit, the maintenance orders. These are created by the maintenance management and make up the actual placing of inspection and maintenance orders with the maintaining party. The concept's third fundamental unit are the numerous master data that have to be administered for a working maintenance.

The important master data for iQ-INST are those data of the device to be maintained and the effective maintenance and work plans. Each device can be made up of an arbitrary deep convoluted hierarchy of device components in form of a bill of materials. One or more maintenance plans are assigned to the device components. These plans describe the maintenance cycles, and each of them can be assigned to an independent work plan.
