You should start by understanding the quality of the existing data. This is best done by conducting a formal objective Data Assessment. Place a stake in the ground and determine the current quality of an aspect of your data that is critical to your business processes. Conduct a Data Assessment and measure the quality of the Data.
On completion of the assessment you will be able to:
- Provide accurate, complete measures of the current quality of the data
- Report statistics and findings in summary scorecards and detailed tables
- Identify the problems that exist within the data
- Identify actions that can be taken to further analyse and improve the quality
When presenting your results:
- Start with the end in sight
- Interpret the results where possible and relate to business :
- What risks exist due to the problems identified?
- What costs are being incurred due to these issues?
- What potential benefits would fixing the problems provide?
- Identify which areas are being impacted by the problems and should support improvement activity being implemented
- Consider who will benefit from Data Quality improvement, directly and indirectly
- Report the statistics graphically where possible for ease of understanding
