felpreventiv

Felpreventiv is a concept in reliability engineering and safety management that describes systematic efforts to prevent faults from occurring, propagating, or causing harm in a system or process. It covers the entire lifecycle—from design and development to operation and maintenance—seeking to reduce both the likelihood and the impact of failures rather than simply detecting and correcting them after the fact.

Key principles include designing for reliability, redundancy and fault tolerance; error-proofing (poka-yoke) and standardization; robust maintenance planning and condition monitoring; and a focus on continuous improvement. Early-stage assessment often relies on risk analysis tools such as Failure Modes and Effects Analysis (FMEA), Failure Mode, Effects and Criticality Analysis (FMECA), and Fault Tree Analysis (FTA) to identify potential faults and their causes.

Implementation practices encompass robust design, modular architectures, component diversity, diagnostic instrumentation, and automatic fault detection and isolation. Preventive and predictive maintenance programs, together with real-time monitoring, are central to felpreventiv in industrial contexts. In software, the approach emphasizes defensive programming, thorough testing, and ongoing monitoring to minimize fault introduction and propagation.

Applications span manufacturing, software systems, transportation, energy, healthcare, and other critical infrastructures where reliability and safety are essential. Standards and governance relevant to felpreventiv include IEC 61508 and ISO 26262 for functional safety, ISO 9001 for quality management, and ISO 31000 for risk management.

Historically, felpreventiv emerged from reliability engineering and preventive maintenance practices in the 20th century and is closely linked to safety engineering and risk management. It complements fault detection and recovery by prioritizing fault prevention at the source.
