Anticipatory failure identification and troubleshooting of new and existing products The implementation of TRIZ and AFI in the companies as an expandable internal platform for innovation and quality management.

Anticipatory Failure Identification AFI

New production methods and systems often only achieve an acceptable standard of reliability after a large number of breakdowns. Therefore, methods of anticipatory failure identification are growing in importance. They help to determine the risk of potential breakdowns even when the experience is lacking.
 
The TRIZ tool for anticipatory failure identification, AFI for short, is an effective and creative method. Amongst the most important applications for this method are the analysis of previous breakdowns which have happened for no apparent reason, as well as the prediction of hidden sources of potential breakdown scenarios or damage.

AFI Procedures

The general procedures of the AFI method consist of the following main stages:

Inverting the task: "What actions will definitely cause a system to fail?" With this method sources of errors are systematically "generated" using both the whole potential of TRIZ and the checklists of typical faults.
 
Identifying all resources of the system and the surrounding for producing failures.
 
Inventing failures systematically using TRIZ innovation principles and effects.
 
Re-inverting the task: using TRIZ tools for the development of fault-avoidance measures. This approach helps to overcome the general tendency to accept compromises.
 
 

FMEA Supplementation

The anticipatory failure identification can effectively supplement existing quality control methods such as FMEA method (Failure Modes and Effects Analysis), HAZOP/PAAG (Hazard and Operability Analysis) or be integrated into other methods.
