Every year, poor data quality costs organizations an average $12.9 million. Apart from the immediate impact on revenue, over the long term, poor quality data increases the complexity of data ecosystems and leads to poor decision making.

The emphasis on data quality (DQ) in enterprise systems has increased as organizations increasingly use data analytics to help drive business decisions. Gartner predicts that by 2022, 70% of organizations will rigorously track data quality levels via metrics, improving it by 60% to significantly reduce operational risks and costs.
“Data quality is directly linked to the quality of decision making,” says Melody Chien, Senior Director Analyst, Gartner. “Good quality data provides better leads, better understanding of customers and better customer relationships. Data quality is a competitive advantage that D&A leaders need to improve upon continuously.”
No. 1: Establish how improved data quality impacts business decisions
Identify a clear linkage between business processes, key performance indicators (KPIs) and data assets. Make a list of the existing data quality issues the organization is facing and how they are impacting revenue and other business KPIs. After establishing a clear connection between data as an asset and the improvement requirements, data and analytics leaders can begin building a targeted data quality improvement program that clearly defines the scope, the list of stakeholders and a high-level investment plan.
No. 2: Define what is a “good enough” standard of data
To improve data quality, first it is important to understand what is “best fit” for the organization. This responsibility of describing what can be defined as “good” lies with the business. Data and analytics (D&A) leaders need to have periodic discussions with business stakeholders to capture their expectations. Different lines of business using the same data, for example, customer master data, may have different standards and therefore different expectations for the data quality improvement program.
No. 3: Establish a DQ standard across the organization
D&A leaders need to establish data quality standards that can be followed across all business units in the organization. It is likely that different stakeholders in an enterprise will have different levels of business sensitivity, culture and maturity, so the manner and speed with which requirements of DQ enablements are met may differ.
“This will enable stakeholders across the enterprise to understand and execute their business operations in accordance with the defined and agreed-to DQ standard,” says Chien. An enterprise wide DQ standard will help educate all involved parties and make the adoption seamless.
No. 4: Use data profiling early and often
Data quality profiling is the process of examining data from an existing source and summarizing information about the data. It helps identify corrective actions to be taken and provides valuable insights that can be presented to the business to drive ideation on improvement plans. Data profiling can be helpful in identifying which data quality issues must be fixed at the source, and which can be fixed later.
It is, however, not a one-time activity. Data profiling should be done as frequently as possible, depending on availability of resources, data errors, etc. For example, profiling could reveal that some critical customer contact information is missing. This missing information may have directly contributed to a high volume of customer complaints and would make good customer service difficult. DQ improvement in this context now becomes a high-priority activity.
No. 5: Design and implement DQ dashboards for monitoring critical data assets, such as master data
A DQ dashboard provides a comprehensive snapshot of data quality to all stakeholders, including data from the past to identify trends and patterns that can help design future process improvements. It can be used to compare the performance over time of data that is critical for key business processes. This enables the organization to make the right business decisions to achieve the desired business objectives based on trusted quality data.
DQ dashboards also reflect the impact of improvement activities, such as incorporating new data practices into operational business processes. They can be customized to meet the specific needs of a business and it shows how much trust you can put in your data.
No. 6: Move from a truth-based semantic model to a trust-based semantic model.
The source of data is not always internal, where data quality can be controlled and maintained right from the beginning. In some cases, data assets are acquired from external sources where the DQ rules, authorship and levels of governance are often unknown. Hence, a “trust model” works better than a “truth model.”
This means that, rather than thinking about key enterprise data as being absolute, organizations must also consider its origin, jurisdiction and governance — and therefore the degree to which it can be used in decision making. D&A leaders can implement mitigation measures when trust levels are not maintained.
No. 7: Include DQ as an agenda item at D&A governance board meetings
D&A leaders need to link DQ initiatives to business outcomes, which will help track the investments in DQ improvement against the business objectives. “To get the board’s attention, it is important that the impact of DQ improvement is communicated to the board in a language they understand best — business and revenue impact,” says Chien. The board needs to have clear visibility of the DQ improvement progress and challenges, and they need to get this information on a regular basis.
No. 8: Establish DQ responsibilities and operating procedures as part of the data steward role
A data steward is responsible for ensuring the quality and fitness for purpose of the organization's data assets, including the metadata for those data assets. In more mature organizations, a data steward’s role is also to champion good data management practices, and monitor, control or escalate DQ issues as and when they occur.
D&A leaders need to include this role in their D&A strategy, so that DQ is measured and maintained regularly in a systematic manner. Create a governance scope and stakeholder map that will allow a clear understanding of how DQ issues are managed.
