5 steps to optimal data quality

Data quality management is one of those concepts that is hard to define and hard to put into practice, let alone that it is clear how a company can best approach the optimization of data quality.

Jack de Hamer, data management specialist at Type 2 Solutions, defined the following five steps based on experience that offer practical help in improving data quality:

Step 1. Define the kind of data to be collected and the elements within that data which should be optimized.

Step 2. Define rules for each data element and automate the control mechanisms.

Step 3. Assign the responsibility for the optimization of a data entity to a single person.

Step 4. Automate data validation according to their definition, and keep the results.

Step 5. Correct exceptions and adjust their definition if necessary.

How does it work?

Data is extracted from the data source of an application (step 1). This data is automatically evaluated by the Data Quality Monitor (step 4), according to the business rules resulting from the data definitions (step 2). Exceptions to those business rules are detected, collected, and presented to the data owner (step 3), who can now take appropriate corrective action, either by correcting the data, or by fine-tuning the data definitions.

By repeatedly going through this process, a continuous improvement of the quality of the data, and of the optimization process leading to it, is achieved (step 5).

How to get started?

Data Quality Scan

To help you on your way with data quality, we offer a Data Quality Scan. During this scan we perform an audit of a current set of data. We load this data into the Data Quality Monitor.


The result is data management advice, including an action plan for cleaning and managing the data. This advice will be presented to you on-site.

Showing the results in the Data Quality Monitor is part of the data quality scan.

Data quality management at Eichholtz

Dennis Hendriks, Director Operations at Eichholtz, shares how they started with data quality management:

“In 2019 we, as Eichholtz, started the collaboration with Type 2 Solutions. What we started with was quite simple, we’ve generated quite a lot of leads through conventions in the past 29 years. This means a large collection of data, data which is far from sanitized. It needed some doing to clean it up.”

Data cleansing

“That’s where Type 2 Solutions provided the answer, by, initially looking broadly at the data and identifying where the mistakes are, removing those mistakes, and enabling us to continue with a clean database. The next step was our switch to a new ERP, which resulted in a clean-up of about 30.000 records.”

Strategic advantage with data quality

Jack de Hamer, data specialist at Type 2 Solutions, wrote an article about ‘Data quality gives companies a strategic advantage‘.

It is not easy to put a price tag on ‘poor’ maintenance. According to Jack de Hamer, this is strongly influenced by its consequences.

“The costs can range from a few euros per customer when mail is returned to thousands or hundreds of thousands of euros in damage as a result of incorrect data on an invoice, customs document or label.”

Invest in a long-term solution

However, according to him, companies should not focus on a specific amount. “I think it’s better if companies want to safeguard their data quality in order to gain a strategic advantage in terms of customer retention or new buyers.” Optimizing and maintaining data quality requires a good plan and discipline.

Optimize your article data

If you would like to exchange your article data with your customers your master data should be in order. Online retailers like Amazon,, Ahold, Intergamma require that you exchange your data according to the GS1 standards. T2S Data Analyst Stefanie Polfliet wrote a blog about ‘GS1 code management – know how’ and the importance of data quality.

“For GS1 codes to be properly managed you need to view them as an important part of your master data. If that doesn’t help because your master data is a tad, well, messy, then I honestly recommend cleaning that up. It can be a bit like paperwork at home, you kept all the important stuff like you should, but it ended up on one big pile that still needs filing et cetera. Trust me, the sooner you clean up that pile the better, it’ll only keep getting messier after all.”
