Data quality

What is data quality?

Data quality is the degree to which your business data is correct, complete, current and consistent, and therefore usable for decisions and for AI.

Duplicate customers in the CRM, outdated addresses, fields filled in differently: it looks small, but every report and every AI application running on it inherits those errors.

AI makes data quality more important, because AI acts directly on the data. At the same time AI helps: it can flag duplicates and deviations and fill in missing data from other sources.

The foundation is that systems are connected and use the same data, so there is one source of truth. How to put that in place for AI is covered under the data foundation for AI. Read more about system integration.
