izchilligi

Izchilligi is a concept used in information governance, data provenance, and supply chain management to describe the degree to which outputs can be traced to their original sources with verifiable records. A high izchilligi implies comprehensive, tamper-evident provenance information that allows stakeholders to reconstruct the full lineage of a product, data item, or decision from inputs to final result.

Originating in Turkic-language contexts, izchilligi combines iz (trace or traceability) with chillig(i) (related to state or condition), forming an abstract noun that denotes traceability as a property of a process or system.

Key characteristics include tied metadata, versioned records, audit trails, and standardized identifiers. Systems with high izchilligi maintain end-to-end chain of custody, support reproducibility, and enable audits by independent reviewers. Privacy and security considerations must balance traceability with data minimization.

It is used in manufacturing to track materials, in software to document data lineage, and in research to ensure replicability. For instance, a data pipeline with complete lineage links raw data, transformation steps, and outputs to the processing code and parameter settings.

Measuring izchilligi involves metrics such as lineage completeness, auditability score, and tamper-evidence of logs. Benefits include improved accountability, regulatory compliance, and quality assurance; challenges include data silos, performance overhead, and privacy constraints.
