felundersökning

Felundersökning, often translated as fault investigation or failure analysis, is a systematic process used to determine the root cause of a malfunction or failure in a system, product, or process. The primary goal is to understand why something stopped working as intended so that corrective actions can be implemented to prevent recurrence. This can range from simple troubleshooting of a household appliance to complex investigations of industrial accidents.

The process typically begins with defining the problem and gathering initial information. This might involve observing the failure, collecting relevant data, and interviewing witnesses. Following this, a detailed examination of the failed component or system is conducted. This can include visual inspection, non-destructive testing, and destructive testing to uncover physical evidence.

Once data is collected and analyzed, hypotheses about the potential causes are formulated and tested. This often involves applying principles of engineering, physics, or other relevant scientific disciplines. The ultimate objective is to identify the specific event or condition that initiated the failure chain.

The findings of a felundersökning are then used to develop recommendations. These recommendations aim to address the root cause and can include design changes, improved manufacturing processes, enhanced maintenance procedures, or updated training for personnel. The successful implementation of these recommendations is crucial for improving reliability and safety in the future. Felundersökning is a critical component of quality management and risk mitigation across many industries.
