felkategorier

Felkategorier (Norwegian for fault categories) are a structured taxonomy used to classify defects, faults, or errors in information technology, manufacturing, and service delivery. They provide a way to describe problems consistently, enabling faster diagnosis, reporting, and remediation. Felkategorier are applied across disciplines to support incident management, quality assurance, and reliability improvement.

The primary purpose of felkategorier is to standardize fault descriptions so teams can triage issues, analyze trends, assign ownership, and measure reliability over time. A consistent categorization aids root-cause analysis, problem management, and communication with stakeholders such as customers and management.

Common felkategorier include:

- User input or validation errors

- Software defects or bugs

- Hardware failures

- Network or connectivity issues

- Configuration or deployment errors

- Data integrity or corruption issues

- Security or permissions errors

- External dependency failures

- Performance or resource exhaustion issues

Classification is typically based on origin (where the fault occurred), impact (severity), and detection (how and when the fault was found). Felkategorier are used in incident logging, ticketing systems, and dashboards to produce metrics, identify recurring problems, and guide improvement efforts.

Limitations include potential overlap between categories, evolving terminology, and the need for regular maintenance to keep the taxonomy relevant. A well-designed felkategori schema should align with broader quality or reliability frameworks, such as IT service management, failure mode and effects analysis (FMEA), and root-cause analysis processes.
