Endtoendfelkontroll

Endtoendfelkontroll is a term used to describe a systematic approach to detecting, diagnosing, and correcting faults across an entire system—from input to output. It emphasizes end-to-end visibility and responsibility for reliability, spanning hardware, software, networks, data, and processes. The goal is to prevent fault propagation, minimize downtime, and ensure consistent behavior under fault conditions. The concept is often applied in fields such as manufacturing, software engineering, IT operations, and telecommunications.

Key elements include end-to-end monitoring and telemetry that collect metrics, logs, and traces across all components; centralized correlation and alerting to identify root causes; robust fault-tolerance mechanisms such as retries, timeouts, circuit breakers, redundancy, and graceful degradation; and proactive risk management including testing and resilience engineering. Techniques like distributed tracing, OpenTelemetry, and log aggregation support end-to-end visibility.

Process aspects involve incident response and post-incident reviews to learn and close gaps; change management to avoid introducing new faults; and continuous improvement through reliability metrics such as availability, mean time to detection (MTTD), mean time to repair (MTTR), and fault rate.

In practice, endtoendfelkontroll requires organizational alignment between development, operations, and business units; a culture of blameless post-mortems; and tooling that can span multiple domains and boundaries, from sensors and embedded systems to cloud services. While challenging to implement, a mature end-to-end fault control program can improve system resilience, reduce service interruptions, and provide clearer accountability for fault handling.
