What it means
The assessment identifies data, purposes, actors, flows, permissions, retention, sharing, safeguards, and potential adverse effects, then records decisions and actions.
Why it matters
A PIA creates a structured point for challenging unnecessary collection, hidden secondary use, weak controls, and unexamined impacts before they become embedded.
Practical focus
- Start before design decisions are irreversible
- Map actual data flows and actors
- Evaluate impact on individuals, not only compliance
- Track mitigation and reassess after material change
Common mistakes
- Completing the assessment after launch
- Copying generic answers from another system
- Ignoring inferred or derived data
- Treating legal approval as proof of low privacy risk
