6 Data Quality Metrics You Can't Afford To Ignore

data quality metrics

Low-quality data costs businesses up to $15 million annually. So, if you want to improve your data quality, and save money, you need to track the right data quality metrics.

What are data quality metrics?

Data quality metrics are the measurements by which you assess your business data. They benchmark how useful and relevant your data is, helping you differentiate between high-quality data and low-quality data.

When faced with budgetary constraints, bureaucracy, complex systems, and an ever-growing list of security and compliance regulations you need to know that your efforts are providing you with higher-quality data.

That's why we've created this list of six different data quality metrics.

1. Completeness

This measures whether all the necessary data is present in a specific dataset. You can think about completeness in one of two ways: at the record level or at the attribute level. Measuring completeness at the attribute level is a little more complex however, as not all fields will be mandatory.

An example metric for completeness is the percent of data fields that have values entered into them.

2. Accuracy

How accurately does your data reflect the real-world object? In the financial sector, data accuracy is usually black or white – it either is or isn’t accurate. That’s because the number of pounds and pennies in an account is a precise number.

Data accuracy is critical in large organizations, where the penalties for failure are high.

An example metric for accuracy is finding the percentage of values that are correct compared to the actual value.

3. Consistency

Maintaining synchronicity between different databases is essential. To ensure data remains consistent on a daily basis, software systems are often the answer.

For example, transaction consistency helps you detect incomplete financial transactions. Once found, you can roll back those errors meaning both balances remain in check.

We saved one client over $800,000 by ensuring phone and email data consistency across their databases. Not bad for a simple adjustment to their data quality strategy.

An example metric for consistency is the percent of values that match across different records/reports.

4. Validity

Validity is a measure of how well data conforms to required value attributes. For example, ensuring dates conform to the same format, i.e., date/month/year or month/date/year.

If we take our previous case study as an example, they relied on direct mail. But, without the correct formatting it was hard to identify household members or employees of an organization. Improving their data validation process eliminated this issue for good.

An example metric for validity is finding the percentage of data that have values within the domain of acceptable values.

5. Timeliness

Timeliness reflects the accuracy of data at a specific point in time. An example of this is when a customer moves to a new house, how timely are they in informing their bank of their new address? Few people do this immediately, so there will be a negative impact on the timeliness of their data.

Poor timeliness can also lead to bad decision making. For example, if you have strong data showing the success of a banking reward scheme, you can use that as evidence you should continue.

But you shouldn’t use the same data (from the initial 3 months) to justify the schemes extension after 6 months. Instead, update the data to reflect the 6-month period. In this case, old data with poor ‘timeliness’ will hamper effective decision making.

An example metric for timeliness is the percent of data you can obtain within a certain time frame, for example, weeks or days.

6. Integrity

To ensure data integrity, it’s important to maintain all the data quality metrics we’ve mentioned above as your data moves between different systems. Typically, data stored in multiple systems breaks data integrity.

For example, as client data moves from one database to another, does the data remain the same? Or, equally, are there any unintended changes to your data following the update of a specific database? If the answer is no, the integrity of your data has remained intact.

An example metric for integrity is the percent of data that is the same across multiple systems.

Moving from data quality metrics to actionable fixes

When the stakes are so high, it's important not to make things worse by applying the wrong data quality management processes. While it’s not brain surgery, a careful hand is still required to keep your data clean so you end up seeing healthy data metrics across the board.

If you combine data monitoring with the right validation and cleansing processes, you’ll be on the right path to improving your data quality.

But there’s one piece to the puzzle that can make all the difference…

Let software do the leg-work so you don’t have to

Because of bad quality data, the Financial Conduct Authority issued fines to twelve firms in 2018, with the damage totaling $42 million. But it’s not only about avoiding fines – reducing data errors will also help grow your business and deliver on its desired outcomes.

We talked earlier about how proactive data validation and cleansing helped one business save over $800,000Well, in the same stroke, they also increased their orders by 12 percent. All by improving data quality. I guess the lesson is to never underestimate the power of a good spring-clean.

While strong data quality management starts with understanding and monitoring the metrics we’ve discussed above, doing this manually is problematic. Not only is it difficult to get right, it also saps time from your development team that could be better spent on implementing strategic change.

However, with the right data quality tools, you can automate the validation and cleansing process at the source, reducing errors, complexity and the time it takes to deliver real value from your data. While poor data quality will continue to drain money from your organization, good data quality will revolutionize your decision-making processes and increase your chances of generating profit.
