What is a data steward?

Growing companies collect more and more data every year. As a result, they need someone to keep that data clean, safe, and reliable. That job belongs to a data steward, who manages large volumes of information in line with the company’s governance rules.

This article explains what a data steward does. Next, it covers the key duties of the role and the main skills you need to do it well.

What is a data steward?

A data steward is the person who manages and protects an organization’s data so it stays accurate, consistent, and secure.

In simple terms, a data steward acts as a custodian of company data. They are accountable for keeping it reliable across teams. Here is what the role covers at a glance:

• Keeping data accurate, complete, and consistent
• Guarding sensitive records and logging security issues
• Enforcing data governance policies that the whole company follows

Data stewards also record data breaches, leaks, and other problems that staff run into. In addition, they help fix data issues by mapping information between different systems.

Key responsibilities of a data steward

A data steward makes sure the data a company handles meets its quality standards. Because of this, the role touches many parts of the business. Here are the main duties.

Data quality management

One core duty is to keep data quality high. So a data steward spends much of their time on the tasks below:

• Building and using data standardization methods
• Running data quality checks to profile and clean records
• Working with data owners and users to fix quality issues

Good data helps a company make smart choices. As a result, careful stewardship gives leaders insights they can trust. The steward also works to improve governance policies, practices, and steps over time.

Data security and privacy

Data stewards are trusted to protect sensitive and private information. So they build and enforce security and privacy rules that match the law. For example, this includes GDPR in Europe and HIPAA for patient records.

In addition, data stewards work closely with IT teams to add safeguards. Their goal is to lower the risk of data breaches before they happen.

Data governance

Data governance means managing and controlling the data a company owns. Data stewards help set up a strong data governance framework, define standards, and enforce best practices.

They also team up with many stakeholders. So data gets classified, stored, and used the right way. When several stewards work across departments, they keep one shared approach and steady data quality.

In short, data stewardship promotes quality, security, and compliance. Over time, this builds a culture where good data habits become normal.

Data documentation and metadata management

Data stewards create and manage documentation so records are easy to search. For example, they set metadata standards, update entries, and keep the notes current.

This helps users grasp what the data means and where it fits. As a result, teams can analyze it and act with more confidence. Stewards also oversee the data lifecycle, from getting records to storing and sharing them.

Data integration and collaboration

Data stewards support data integration across systems and teams. So they work with data architects and developers to design and run integration plans. This keeps information consistent and coherent.

They also talk with business users and analysts. Because of this, they learn what each team needs and guide them on how to read and use the data.

Skills required for a data steward role

A data steward needs a mix of skills to manage a company’s data well. Here are the main ones the role calls for.

Knowledge of data management

Data stewards must understand governance, data quality, modeling, and metadata. In addition, they should track best practices and new trends in the field.

Problem-solving skills

Data problems can be complex. So data stewards need strong analytical and problem-solving skills. They should spot issues, find the root cause, and offer clear fixes. Attention to detail matters too, since it keeps data accurate and reliable.

Communication and collaboration skills

Technical skill is not enough on its own. Data stewards also need good business communication and teamwork.

They act as a bridge between technical and non-technical staff. So they must turn jargon into plain terms for business users and leaders. Strong people skills help too, because their reading of the data can shape big decisions.

Programming skills

Not every data steward is an expert coder. Still, a basic grasp of programming helps a lot. With it, they can automate tasks and analyze data faster.

Most data stewards know SQL, Python, or R. For example, they write scripts to handle large datasets and run complex jobs.

Strategic mindset

Finally, data stewards need a strategic mindset. So they can line up data work with company goals. They must grasp the business context and spot chances to add value.

A steward with this mindset can read trends in the data they manage. As a result, they can plan ahead and build strategies that fit changing business needs.

Hiring a data steward

Hiring a data steward takes care, since they will handle big data. Beyond the skills above, look for a solid background in data management. For example, many firms prefer candidates who hold a certification such as the CDMP.

A good steward also supports data lineage. In other words, they trace where data starts and follow how it moves across systems.

There are a few ways to hire. Large firms often bring stewards in-house for closer control. Meanwhile, startups can hire freelancers or outsource data management instead. Either way, strong data security in outsourcing should stay a top priority.

In the end, data stewards are key to good data governance. As a result, they support better decisions, smoother operations, and stronger company performance.
