The most successful organizations in the world are data-driven businesses. Data is at the core of the business of many organizations as one of the most important assets, since the decisions they make cannot be better than the data on which they are based. Due to this reason, organizations need to be able to trust their data. One important activity that helps to achieve data reliability is the evaluation and certification of the quality level of organizational data repositories. This paper describes the results of the application of a data quality evaluation and certification process to the repositories of three European organizations belonging to different sectors. We present findings from the point of view of both the data quality evaluation team and the organizations that underwent the evaluation process. In this respect, several benefits have been explicitly recognized by the involved organizations after achieving the data quality certification for their repositories (e.g., long-term organizational sustainability better internal knowledge of data, and a more efficient management of data quality). As a result of this experience, we have also identified a set of best practices aimed to enhance the data quality evaluation process.

世界上最成功的组织是数据驱动型企业。数据作为许多重要资产之一，是许多组织业务的核心，因为它们做出的决策不会比其所依据的数据更好。由于这个原因，组织需要能够信任他们的数据。帮助实现数据可靠性的一项重要活动是对组织数据存储库的质量级别进行评估和认证。本文介绍了将数据质量评估和认证过程应用于属于不同部门的三个欧洲组织的存储库的结果。我们从数据质量评估团队和进行评估过程的组织的角度提出调查结果。在这方面，例如，长期的组织可持续性可以更好地了解数据内部知识，并可以更有效地管理数据质量。有了这些经验，我们还确定了一组旨在增强数据质量评估过程的最佳实践。
