A number of years in the past, our information platform workforce aimed to pinpoint the first considerations of our information customers. We performed a survey amongst people interacting with our information platform, and unsurprisingly, the principle concern highlighted was information high quality.

The preliminary response, attribute of our engineering mindset, was to develop information high quality tooling. We launched an inner device named Contessa. Regardless of being considerably cumbersome and necessitating vital guide configuration, Contessa facilitated checks for traditional dimensions of knowledge high quality, encompassing consistency, timeliness, validity, uniqueness, accuracy and completeness. After operating the device for a few months with tons of of knowledge high quality checks we concluded that:

  • Knowledge high quality checks sometimes assisted information customers in discovering, in a shorter timeframe, that the information was compromised and couldn’t be relied upon.
  • Regardless of the frequent execution of knowledge high quality checks, there was no noticeable enchancment within the subjective notion of knowledge high quality.
  • For a good portion of points, significantly these recognized by means of automated information high quality checks comparable to consistency or validity, no corrective actions have been ever taken.

Certainly, I like to recommend this to anyone, as one-on-one conversations helped us uncover one other essential angle of the state of affairs. A few of these conversations unfolded as follows:

We are able to see additionally the precise income per product, however not on the order granularity.”
