Gartner: Unternehmen benötigen Data Stewards zur Sicherung ihrer Datenqualität

Poor data quality severely inhibits many strategic business initiatives such as customer relationship management (CRM), business intelligence (BI) or any effort requiring significant integration of data.  A recent European Gartner BI survey of more than 600 BI users found that more than 35 per cent identified data quality as a top-three BI problem facing their organisation in the next 12-18 months, making it the second biggest challenge overall.

To alleviate this problem, Mr Bitterer recommends that each major business function have data stewards, including sales, marketing, service, production, finance, HR and IT.  ”Successful and effective data stewards reside in the business, are visible, respected and influential – they must have the vision to understand the importance of data quality to the overall business objectives, as well as the impact of quality issues on downstream business processes,” he added.  The leader of the steward team, i.e. the corporate sponsor for data quality, will serve as the ultimate point of decision on issues and conflicts occurring across stewards and teams.

“Many data stewardship programmes have resulted in little or no improvement because the organisation selected the wrong individuals as stewards or because those individuals were not organised and managed in a way that ensures success,” Mr Bitterer said.  Successful stewards are placed closest to the point of data capture and maintenance, are intimately knowledgeable about the data and its use in a business context. They have also a stake in improving quality.  As such, they are empowered to make business process changes and apply resources to address quality issues. Furthermore, they can influence how their peers execute business processes to achieve further improvements.

In addition, stewards are in an ideal position to help with an effective governance strategy for data quality, since governance must cascade across the entire organisation to ensure that appropriate accountability is enacted and enforced.

According to Gartner, the governance duties of stewards are to:

Ensure the consistency and accuracy of data as it flows from one application to the next. Implement governance tasks and achieve data quality metrics pertaining to the accuracy and completeness of information in their domain. Be responsible for the elements that support data sharing and master data management objectives (such as official product hierarchies, valuation models, customer segmentation profiles and preferred suppliers). Support ongoing profiling activities and identify issues with source systems (such as calculation routines and missing values). Create or update document taxonomies and actively participate in the semantic reconciliation of data models.
