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

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 …

Page 23: Data quality sunz 2012

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!

Page 24: Data quality sunz 2012

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 …
