Presentation Transcript

  1. Internal audits in the CZSOand their impact on National Accounts Vítězslav Ondruš, CZSO Vladimír Kermiet, CZSO

  2. Presentation consists: • System of internal audits in CZSO • Internal audits on National Accounts • Internal audits on main data sources 2

  3. System of internal audits in CZSO(1/5) • System of periodical internal audits was adopted by top management in 2003 • aim and expected outputs of audits - main attributes of quality were investigated: Relevancy (relevance, importance), Accuracy, Seasonableness,Availability, Comprehensibility, Coherency (connection, continuity • role of auditors was defined and audit‘s groups were created by external (mainly academic) and internal experts • audited statistics (departments) were chosen and time schedule of audits was adopted 3

  4. System of internal audits in CZSO(2/5) • The first cycle of 23 internal audits (all statistics): period from 2003 to 2008 –covered • System of internal audits started in the Quarterly National Accounts Department during the 4th quarter 2003 • Annual national accounts were audited in 2004 4

  5. System of internal audits in CZSO(3/5) Standard practise: • Auditing group usually consists of 3 external and 2 internal experts • Outcome: Final report prepared according to the general scheme • Final report was discussed by the top management, the head of auditing group and director of audited department • Time schedule of further steps was usually prepared and monitored 5

  6. System of internal audits in CZSO(4/5) Standard practise - final report consisted mainly of: • Audit assignment including rough time-schedule • Correspondence between standards and practice of EU statistical service • Satisfaction of users needs (statistical outputs) • Assessments • sufficiency of written methodology documentation   • quality dimensions of output (like in EUROSTAT quality report) • benchmarking • Suggested further actions and improvements (including opinions of auditing group members)6

  7. System of internal audits in CZSO(5/5) Future works: • The first round of internal audits has been evaluated by the Czech Statistical Council as satisfactory and highly appreciated work • The second round is anticipated – arrangements are almost completed 7

  8. Internal audits on National Accounts(1/6) • Quarterly national accounts (2003) - important findings and improvements: • Inadequacy of written documentation • the written documentation,,QNA Inventories” was completedin the year 2008 • Relevance - it took very long time to revise quarterly data after publishing ANA • new revision policy was established: the QNA data are revised promptly in next quarter after the ANA data are published 8

  9. Internal audits on National Accounts(2/6) • Quarterly national accounts (2003) - important findings and improvements: • Accuracy – there were some doubts about basic data quality resulting from sampling errors and non-sufficient sample size • responsibility for source data is now clearly defined by new system of SLA • Availability –at the time of the audit the usual praxis quarterly estimates were publish not untilT+70 to T+100 • flash GDP estimates have been published strictly in T+45, QNA in T+70 and QSA in T+90 9

  10. Internal audits on National Accounts(3/6) • Quarterly national accounts (2003) - important findings and improvements: • Coherency - non-coherency of NA and relevant short-term statistics was identified • it is the most complicated finding - working group for coherency, compatibility and consistency (CoCoCo) has been established, however the solution to this issue has not been found yet and the non-coherency still exist 10

  11. Internal audits on National Accounts(4/6) • Annual national accounts (2004) - important findings and improvements: • Inadequacy of written documentation • written documentation,,GNI Inventories” was completedin 2006 • Availability – not clearly define publishing schedule for ANA • new revision policy was established and strictly fulfilled: preliminary version of ANA in T+9 month, semi-definitive version in T+18 and definitive version in T+30 11

  12. Internal audits on National Accounts(5/6) • Annual national accounts (2004) - important findings and improvements: • Comprehensibility - NA data were published without any meta-information and published structure could lead to confusion • new NA web sites including methodological explanations were established in 2006 - this system is permanently updated, supplemented and improved 12

  13. Internal audits on National Accounts(6/6) • Annual national accounts (2004) - important findings and improvements: • Comparability and coherency–many lacks of comparability with branch statistics were found - itis the biggest deficit in CZSO • some particular shortcomings have been resolved under the CoCoCo (coherency, consistency and comparability) working group • general reason of incomparability and incoherency still exists – it is question of the role of individual statistics, their interrelations and harmonization of their revision policy • this issue should be one of the most important topics of next round of internal audits 13

  14. Internal audits on main data sources for ANA(1/3) • Statistical business survey (2005) - important findings and improvements: • Extensiveness of questionnaire – questionnaire was assessed as too extensive, bringing a significant administrative burden and not reflecting specifics of individual industries • small reduction of questionnairehas been done yet without conceptual discussion • next reduction is prepared for 2010 year, but also without deep conceptual discussion • conceptual discussion about role of administrative and statistical data sources started this autumn 14

  15. Internal audits on main data sources for ANA(2/3) • Statistical business survey (2005) - important findings and improvements: • Using of administrative data – assessed as an insufficient and recommended to focus on changes in legislation limits • legislation limits have been removed • regularly updated databases of ADS (mainly tax declarations and financial statements) has been in disposal for the CZSO since 2007 • until now any concept of direct use of ADSis missing. 15

  16. Internal audits on main data sources for ANA(3/3) • Statistical business survey (2005) - important findings and improvements: • Outputs of data processing –significant shortcomings and inconsistenciescaused by using of different outputs of data processing were identified (mainly due to different revision policy in NA and SBS) • basic rules for data processing and using of final outputs have been adopted and incorporated into SLA • still not yet any agreement concerning preliminary outputs (NA use August version and SBS use October version) 16
