ESS VIP project on Validation

This project aims to standardize validation processes, enhance data coherence, and improve quality across statistical domains. It addresses the need for change in validation procedures, harmonization, and IT solutions, with milestones set for 2013-2020. The project involves collaboration with Member States and Eurostat to ensure data integrity and quality results.

  1. ESS VIP project on Validation Presented by: Pedro Díaz EUROSTAT

  2. CONTENT • Scope & objectives • Business case • Link with previous projects & maturity • Proposed approach & milestones • Next steps

  3. Scope & objectives • Documentation / Standardisation • Methodological analysis of Data Validation • Distribution of responsibilities in the production chain • Preparing for IS/IT solutions and architecture

  4. Scope & objectives • Coherent validation policy in the different statistical domains, in cooperation with MS. • Standard validation language • Solutions for complex validation actions to ensure: • Coherence between data files • Coherence between Member States • Integrity of the ESS data

  5. Scope & objectives Contribution to the VISION:

  6. Business case: Need for change • Two steps circular validation process • Step 1: Validation in Member States • Step 2: Validation in Eurostat • Lack of harmonisation • In documentation (validation procedures & rules) • In coordination: "Validation ping pong" • In software solutions • Subjective assessment of data quality • Risk of low quality results

  7. Link with previous projects & maturity

  8. Link with previous projects & maturity • Favourable reaction of Member States in • ITDG: Oct 2011 • DIME: March 2012 • ESSC: May 2012 • Working Groups

  9. Proposed approach & milestones Packages:

  10. Proposed approach & milestones

  11. Next steps: 2013 - 2014 • Data sent to Eurostat already validated (push mode, in-file validation, micro-macro) • Enablers: • Descriptive syntax • Governance mechanism with Member States • Implementation monitoring • Adaptation of IT Tools • Micro data specificities

  12. Next steps: 2014 - 2020 • Extended validation (across files, time series) • Need for shared databases • Need of shared tools • Mirror checks: One country checking after countries' data • Confidentiality treatment • Enhancement of transmission tools • Change roles (Member States, Eurostat) • Pull and shared modes • Common warehouses • Census hub technologies • Change roles (Member States, Eurostat)

  13. Next steps Why an ESS VIP? Role of NSI's in project phases • Methodological Task Force • Validate phase-1 deliverables • Advise on implementation/monitoring • Definition of ESSNet work ESSNet

  14. Next steps Why an ESS VIP? Role of NSI's in project phases • Methodological Task Force • Validate phase-1 deliverables • Advise on implementation / monitoring • Definition of ESSNet work ESSNet
