Master Data Management Tips: Managing Data Stewards

by | Mar 15, 2018 | Master Data Management

The extent to which rules can be used to resolve the conflicts and ambiguities arising from inconsistent and incomplete data is limited. At some point, it becomes necessary to turn to data stewards to apply human reasoning and additional research into the data. Many factors determine the amount of work required by data stewards, but in some cases, the workload can be significant. In this article, we discuss some of the important considerations when planning and managing a large data stewarding effort.

Short Sprints

Breaking down many data stewarding events into smaller groups makes it easier to create and maintain enthusiasm within the data steward team. Just as it’s easier to convince someone to run a quarter-mile than a full marathon, data stewards will more readily tackle a series of small groups of records than one long list.

Even in situations where there is a backlog of thousands of data stewarding events, breaking these into smaller groups of a few hundred records allows each steward the satisfaction of starting and finishing a set of records several times a day.

Communicate Policy Clearly

Data stewards are called upon to review situations that cannot be resolved by rules which typically imply that these situations are complex or ambiguous. A downside to human intervention is that people are less consistent than computers and this inconsistency is exaggerated in these complex/ ambiguous situations if the policy for managing these situations is at all unclear.

It is important that the policies and decision trees used by stewards are clearly documented and communicated to all stewards.

Suspense Queue

There will be situations where the data steward does not have enough information to make a decision. Providing some mechanism to move these records out of their queue allows the steward to continue to make forward progress and does not skew the time-per-record statistics that are so important to managing the stewarding process. Another advantage of a “suspense queue” is that these records can be more thoroughly analyzed to determine why they are more difficult to resolve.

Screen Design for Efficiency

User-friendly screens do not imply pleasing-to-the-eye designs but rather efficient-to-the-hands layouts. Your design must optimize the number of key-strokes required for any action and certainly minimize the number of time-consuming mouse movements.

Data stewards need to assess the data on the screen and action their decision with minimal fuss. Stewards will not thank you for elaborate fold-out lists and pop up information boxes no matter how pleasing the design.

Gather Feedback

Data stewards are the best people to comment on the efficiency of master data rules and they should be encouraged to provide feedback to the data management/governance team. Stewards will quickly identify patterns that may help the data management team for further investigation. Sometimes simply adding additional cleansing rules may help resolve hundreds of administrative hours per year.

Quality Assurance

Data stewards are often the last line of defense for enterprise data quality. There is no safety net for many decisions entrusted to data stewards and therefore it is important to have a solid quality program in place. A mistake made by a data steward will typically only surface as an error in some downstream process. It is worthwhile to trace these data errors back through the MDM process to the data steward. Data stewarding decisions should be traceable to individual stewards as poorly trained or careless stewards will quickly show a deviation from the mean error rate.

In our experience data stewards produce an error rate of much less than 1% of the decisions they make. Poorly trained or careless stewards will typically show a far higher error rate and therefore they can be easily identified and corrected.

Summary

Data stewarding is a mundane administrative task that adds time and cost to any MDM initiative. However, it is unavoidable in many circumstances, and building a trustworthy, efficient data stewarding process is a key success factor for sustainable data quality. Data stewards provide a key role in the MDM lifecycle and their role should be given the time and attention that it deserves.
