Article 11 requires a report describing, in a detailed and transparent manner, the measures implemented to ensure compliance, plus a non-confidential summary. The Commission template makes that evidence concrete: it asks for the pre-measure situation, implementation timing, product and geographic scope, technical or engineering changes, customer-experience changes, remuneration and terms changes, consultation records, alternatives assessed, impact testing, indicators, and internal monitoring tools.
The compliance program should therefore collect evidence continuously, not only near the reporting deadline. Product teams should attach engineering tickets, API documentation, data-flow descriptions, screenshots, recorded demos for user journeys, terms updates, experiment methodologies, survey results, and metric definitions to the same control record that supports the Article 11 annex.
