The challenge

Vodafone UK BI needed to provide greater assurance on the data that was used by the business as part of their Data Excellence programme.

This needed to have an automated and innovative approach to measuring the ‘quality’ of their data as it flowed through their various systems, including their enterprise data warehouse and onto the business-facing reports via a presentation tool.

 

 

 

 

 

 

 

 

How we did it

Using a combination of our process heritage and data analysis skills, we have created a cloud-based tool which maps and monitors the flow of data.

Treating the data as a ‘product’ we applied statistical and monitoring techniques to be able to assess the quality of the data through the various stages of its processing. This included enrichment, suspense, matching and staging.

The tool has been built from the ground up, utilising modern pipeline techniques to take daily snapshots of the core enterprise data warehouse and apply rules to understand the changes in data quality over time.

Outcome

We continue to work with Vodafone in realising the full potential of the data assurance tool.

At present the tool is being used to:

  • Provide a kitemark of assurance on 5 key indicators.
  • Deliver high-level analysis of trends that can help understand reasons for falls in data quality.

We continue to build out new features that extend the reach to cover more indicators and use cases.

We are also building out ‘proof of concept’ projects to explore more advanced capabilities within the tool to help spot areas for predictive analytics.
