What is a product score?

How can Atlan help you build trust in your data products? Product scores!

Based on the principles of data as a product, product scores can help you signal the accuracy and completeness of your data products, helping build trust in them. The product scorecard in Atlan enables you to:

  • Identify and prioritize data quality issues
  • Quantify the business impact of data quality
  • Drill down for detailed analysis and take action
  • Share insights across stakeholders
πŸ’ͺ Did you know? You can also choose to hide the product score from your data products. Contact your Atlan admin to turn off the product score from the admin center.

Components of a product score

Atlan calculates and assigns a product score to your data products based on a preset criteria of metadata completeness. Atlan evaluates metadata enrichment on the data product, output ports, or a combination of both. Using a weighted scoring method, values are automatically assigned on the basis of how well your data product satisfies the six principles of data as a product. Atlan scores your data product on a scale of 0-5, with 0 being the lowest and 5 being the highest score.

The six principles of data as a product are:

  • Discoverable: The discoverability of a data product is based on the availability of aggregate metadata. Atlan quantifies discoverability in the form of glossary terms linked to the data product and output ports.
  • Understandable: A data product is considered to be understandable when it has defined and curated contextual metadata to help your data consumers understand the product better. Atlan quantifies how understandable a product is in the form of:
  • Addressable: A data product is considered to be addressable when it has well-documented owners and points of contact. Atlan quantifies how addressable a data product is in terms of owners assigned to the data product and its output ports.
  • Secure: A secure data product will clearly signify the sensitivity of data. Atlan quantifies how secure a data product is on the basis of sensitivity classifications on the data product and tags attached to its output ports.
  • Interoperable: Interoperability of a data product is determined on the basis of the visibility and completeness of technical lineage between data assets.
  • Trustworthy: Trustworthiness of a data product is determined on the basis of certificates and data contracts attached to the data product.

A product score is not set in stone, and will change depending on the completeness of metadata enrichment. The score can help you understand how to improve your data product to make it more useful for your data consumers.

Atlan currently does not allow you to either configure the score or define your own criteria.

Scoring rubric

Scoring method

To calculate the product score, Atlan uses a weighted scoring method:

  1. Assign scores for each principle β€” Atlan assigns a score based on each of the principles to determine a product score within the range of 0-5.
  2. Set weights for each principle β€” Atlan determines the weight of each principle based on the completion rate of metadata enrichment.
  3. Calculate weighted scores β€” the score for each principle is multiplied by its weight. For example, if Trustworthy has a score of 4 on a scale of 5 and a weight of 30%, the weighted score would be 4 * 0.3 = 1.2.
  4. Sum up the weighted scores β€” Atlan adds up the weighted scores for each principle to arrive at a total score, which is displayed on the data product.
  5. Interpret the score β€” you can use the total weighted score to evaluate the data product's overall alignment with the principles of data as a product. A higher score will indicate closer alignment with the principles and metadata completion.
