For accountability, businesses should record which decision is automated, which sources and features are used, which Article 22(2) GDPR exception is relied on and which safeguards are available. The record should also cover the information notices, the route to human review, responsibility for challenges and retention of the relevant decision record.
Common errors arise when a score is treated as the decision without checking the final human step. Another weakness is a general privacy notice that explains neither the significance of the assessment nor how to challenge it. There may also be a gap between the business and the external model provider. A business using an external model must understand the relevant sources, currency and logic well enough to assess its own processing.
Before changing the model, the organisation should check whether the data, groups, thresholds or effects have changed. The privacy compliance and governance topic supports the organisation of responsibilities and evidence. A clear review trail is especially important where automated decisions repeatedly affect many people in the same way.
