  17. 17. ACC Data QualityGuiding Principles 1. ACC will manage data as a core organisational asset with decisions made based on value and the greater good of ACC and its stakeholders 2. The Data Council is mandated as the only forum for ratifying semantics, definitions and business rules for the use of data 3. Use industry and international data standards whenever, and as current, as possible 4. Data quality will be measured across the value chain and all data consumers will have a voice in specifying data quality service level agreements 5. Business process owners will agree to and abide by data quality Service Level Agreements 6. Data masters will be the primary source for any further use of that data 7. Validate data instances and data sets against defined business rules 8. Apply data corrections at the original source, if possible 9. Data entry and system integration will be automated whenever possible with validation applied on entry 10. System user interfaces will be designed to assist and encourage data quality 11. Reference data is current and relevant 12. All data entities will be semantically unique and defined 13. Metadata will be available to all data consumers 14. All report development will be peer reviewed 17
  18. 18. Data Quality Initiatives Improving Client Information • Reducing number of client duplicates created – 350,000 duplicates (60,000 P.A.) – Staff were trained and Eos improved – Rate reduced from 18% to 8% • Improving NHI, Date of Death (DOD) – Collaboration with MOH – Improve valid NHI from 49% to 81% – Provide DOD for 345,000 clients 18
  19. 19. RFI: Data Quality Tools Data Quality Tools & Processes • To be used for: – Analysis of data quality – Address cleansing, standardisation and validation – Duplicate identification and elimination – Monitoring and managing data quality • First application Client address standardisation and verification 19

  22. 22. The Business Case • Financial Savings – NZ Post – Rework – Error recovery • Reputational Risk Mitigation – Minister/Public/Clients • Process Support – Data cleansing/verification – Data matching/lookup (Master Data) • Ease of development/reuse/monitoring This is on paper … 22
  23. 23. Not on paper • Data governance was working – Used as a ―sanctioning committee‖ • Data quality must be addressed – Tools will help to do this – We must have tools • Confusion – Data Quality vs Text mining – What do the tools actually do? – How do you use them (development) – How can they help? • Current Image: Anything to do with data can be fixed with the tools! 23
  24. 24. Summary• Procurement highly influenced by: – Non-paper justification – Reputation of Data Governance – Data quality is a ―big‖ problem• Lots of confusion – Needs lots of education/mitigation – Evaluation panel needed lots of coaching• The organisation was ―ready‖• The business case … well … 24
