🤔Conducting a data quality assessment at Airbnb
✅Airbnb is an online platform for posting and searching for short-term rentals of private housing around the world.
I recently came across an article, where the author describes the process of developing and implementing a data quality assessment methodology, as well as the principles, criteria, and parameters used for this assessment.
As the author notes, the assessment is based on the following principles:
1. Full coverage is an assessment method that can be applied to all data from an entire array, ensuring analysis and processing of information without omissions or limitations. This principle allows for a more complete and accurate study of data, covering the entire set, regardless of its volume or complexity.
2. Automation is a process in which the collection of input data required for the assessment is fully automated, without the need for manual intervention. This principle ensures high speed, accuracy and efficiency in collecting and processing data, which improves the quality of analysis and reduces the time for decision-making.
3. Actionable is a characteristic that means that the data quality assessment is easily accessible and understandable for both producers and consumers of data. This ensures transparency and ease of use of the assessment results, which contributes to more effective interaction and increased trust between all parties.
4. Multidimensionality is a property of the assessment that allows it to be decomposed into various basic components of data quality. This helps to analyze in detail individual aspects affecting the overall quality, such as accuracy, completeness, relevance and consistency, providing a deeper understanding and the ability to target improvement of each component.
5. Evolvability is a characteristic of the assessment, meaning that the criteria and their definitions can adapt and change over time. This flexible approach allows the assessment to remain relevant and effective in the face of changing requirements, new data and technological advances.
