Quality management, monitoring, evaluation plans and reports
8.1. A quality policy ensures that the producers of official statistics systematically assess the quality of official statistics. Quality policy is publicly available through guidelines, framework, reports, etc. and staff members receive appropriate training for their application.
8.2. An efficient, and possibly independent, quality management system exists. It includes an appropriate organisational structure; quality indicators and other tools and processes for the planning, implementation, and monitoring of the quality of source data; and the collection, processing, and dissemination of official statistics.
8.3. The national quality management systems are based on recognised models for quality frameworks, such as the IMF Data Quality Assessment Framework (DQAF), the European Foundation for Quality Management, European Code of Practice, the European Statistical System Quality Assurance Framework, Total Quality Management and ISO EN 9001, etc.
8.4. There are regular and thorough reviews of key statistical outputs involving external experts where appropriate (ECoP).
8.5. Quality assessment and certification processes guarantee the official nature of statistics produced in various parts of the NSS.
8.6. The organisational structure of the entities belonging to the NSS and governance arrangements are appropriate and regularly reviewed to assess and justify new statistical demands and related costs.
8.7. Information and communication technologies are regularly monitored and assessed for use in data collection, data processing and data dissemination.
8.8. Source data, intermediate results and statistical outputs are regularly assessed and validated (ECoP).
8.9. National Statistical Authorities put in place processes to ensure that sampling and non-sampling errors are measured, systematically documented, and that information is made available to users.
8.10. Studies and analysis of revisions are regularly conducted according to transparent procedures and the results are made available to users.
Timeliness and punctuality
8.11. Timeliness meets international statistical release standards.
8.12. The periodicity of statistics takes into account user requirements as much as possible (ECoP).
8.13. A standard day time for the release of statistics is made public. (ECoP)
8.14. Preliminary results of acceptable aggregate accuracy are released when considered useful. (ECoP)
Coherence and comparability
8.15. Official statistics are consistent within datasets (i.e. elementary data are based on comparable concepts, definitions and classifications and can be meaningfully combined), across datasets (i.e. data are based on common concepts, units, definitions and classifications, or that any differences are explained and can be allowed for) and over time (i.e. data are based on common concepts, definitions, units, classifications, and methodology over time, or that any differences are explained and can be allowed for).
8.16. Statistics from the different sources and of different periodicity are compared and reconciled (ECoP).
8.17. Statistics are compiled according to common standards with respect to scope, definitions, classifications, and units in the different surveys and sources. (ECoP)
8.18. Processes are in place to consult users, monitor the relevance and utility of existing statistics in meeting their needs, and consider their emerging needs and priorities. (ECoP)
8.19. User satisfaction surveys are undertaken on a regular basis. The results are publicly released and considered as an input for decisions about plans and priorities and they are reflected in the statistical work programmes.
