FAQPage Schema
How do I detect user persona drift in my product backlog?

User persona drift is detected by analyzing backlog signals, implemented features, and agent-memory patterns to surface alignment gaps between documented VPC attributes and actual delivery. This produces per-persona drift scores and concrete recommendations.

What is VPC persona drift and how is it measured?

VPC persona drift is the misalignment between defined user personas and actual usage patterns. It is measured by fusing cross-backlog and feature signals to generate per-persona drift scores, identify drifted attributes, and output structured JSON or Markdown reports.

How do I fix persona alignment gaps in my VPC?

To fix persona alignment gaps, the analysis generates actionable VPC update recommendations across multiple phases based on detected drifted attributes. It uses keyword-based matching and semantic assessment to provide clear drift levels and misalignment indicators.

Can I export VPC drift reports in structured formats like JSON or Markdown?

Yes, VPC drift reports can be exported in structured JSON or Markdown formats. The system outputs per-persona drift scores, drifted attributes, and concrete VPC update recommendations with clear drift levels and misalignment indicators for downstream use.

Does VPC drift detection require external dependencies or components?

VPC drift detection operates without external dependencies or components, relying on internal analysis of backlog signals, implemented features, and agent-memory patterns to evaluate alignment gaps and generate per-persona drift scores.

When should I run a VPC drift report for my project?

You should run a VPC drift report when documented user personas potentially diverge from actual delivery. The analysis identifies drifted attributes and alignment gaps using semantic assessment and cross-backlog signal fusion to recommend VPC updates.
