Call Transfer Graph Loop Analysis
A reproducible research protocol for which routing paths create repeated transfers without accepted ownership with bounded authority, traceable evidence, and caller-safe recovery.
Published October 12, 2026.
Research question
Call Transfer Graph Loop Analysis asks which routing paths create repeated transfers without accepted ownership. The unit of analysis, observation window, eligible population, exclusions, and intended operational decision must be registered before outcomes are inspected. The study reports evidence for a bounded call workflow; it does not certify a vendor, infer caller intent, or establish a universal performance benchmark.
Freeze the population and rule versions
In stage 1 of Call Transfer Graph Loop Analysis, retain source queue, destination queue, hop sequence, acceptance event, fallback, caller exit, and final owner. Link events with stable call and workflow identifiers rather than names or approximate timestamps. Preserve original timezones and source values, then add normalized fields separately. Report eligible, observed, excluded, unavailable, late, conflicting, and unresolved records as separate counts. This prevents a clean subset from silently representing the difficult calls most relevant to which routing paths create repeated transfers without accepted ownership.
Stage 1 of Call Transfer Graph Loop Analysis, freeze the population and rule versions, uses a predeclared classification guide and a second reviewer for a planned subset. Reviewers work independently before adjudication and record why competing classifications were rejected. Segment results by workflow version, queue, channel, shift, language or network condition only when that comparison was specified and sufficiently populated. An association may motivate a controlled test; it does not by itself prove that one factor caused the outcome.
Privacy at stage 1 of Call Transfer Graph Loop Analysis requires pseudonymous study identifiers, minimum necessary fields, role-based access, a retention owner, and approved references to restricted recordings or transcripts. Do not copy customer profiles or credentials into an analysis file. Publish denominators and uncertainty, not worker rankings from small samples. Any operational response names its accountable owner, effective time, stop rule, rollback, and follow-up observation window.
Preserve event lineage
In stage 2 of Call Transfer Graph Loop Analysis, retain source queue, destination queue, hop sequence, acceptance event, fallback, caller exit, and final owner. Link events with stable call and workflow identifiers rather than names or approximate timestamps. Preserve original timezones and source values, then add normalized fields separately.
