Data quality: importance and how to achieve it effectively

Written by London Consulting Group | Apr 16, 2025 7:00:00 AM

Data is one of the most valuable digital assets for companies, as it allows them to make strategic decisions that provide competitive advantages.

With the growing accumulation and use of information, data quality becomes a necessity to ensure its quality, to avoid duplicates and errors that affect the operation of organizations.

Therefore, we are going to explain the importance of data quality and how to achieve it within your company.

Importance of data quality in companies

For organizations, it is essential to ensure that the data they collect, store, and use is accurate, up-to-date, and consistent.

In this sense, data quality ensures that the data meets the quality standards and requirements necessary for its use. This avoids problems such as the following:

Poor decision-making.

If the data used for decision-making is incorrect, outdated, inaccurate or incomplete, actions will be based on biased information, which can lead to operational problems and poor process execution.

For example, if a sales team analyzes a report with outdated information about potential customers, it could focus on leads that are no longer interested or do not fit the ideal profile, which represents a waste of time and resources.

Lost opportunities

Poor quality data can limit the understanding of the customer, their buying preferences, consumption habits and frequency, thus hindering a personalized offer of products or services that raise their level of satisfaction.

Additional costs

Data errors generate extra costs for organizations. From correcting records to wasting time in inefficient processes, the lack of data quality can represent a significant drain of money.

A clear example occurs with email marketing campaigns. If a company's database contains erroneous or duplicate addresses, mailings can generate bounces, affect the deliverability rate and even damage the reputation of the domain.

Regulatory compliance issues

Improper handling of data can affect internal operations and lead to legal problems.

In Mexico, for example, the Federal Law for the Protection of Personal Data establishes guidelines on the storage and use of personal information. Therefore, if a company does not comply with the corresponding regulations, it may receive sanctions or even face lawsuits from users.

Having a solid data quality strategy in place helps ensure that all data is accurate and protected, reinforcing the trust of customers and partners.

Characteristics of data quality

There are certain standards that data must meet to ensure accuracy, timeliness, consistency and relevance. The most important of these are:

Accuracy

Data must be accurate and accurately reflect the current status of the objects or events they represent (dates, addresses, contacts, etc.). Any error, whether typographical, computational or input errors, can affect analysis and decision-making.

For example, if a logistics company handles inaccurate addresses, there may be delays or missed deliveries.

Completeness

Data quality must ensure that data is complete. Missing information in a customer base or records can affect business operations.

To this end, it is recommended to identify which data are essential and establish mechanisms to avoid incomplete records, such as forms with mandatory fields.

Consistency

Data must be uniform in all the company's systems. Many times, there are duplications or misalignments between platforms, generating contradictory reports that affect decision-making.

It is essential to establish data standardization protocols and ensure compatible integrations between systems.

Currentness

Data should reflect the most recent state of reality. Outdated information can affect areas such as customer management.

It is recommended to establish periodic review processes and automation of CRM, which allow real-time synchronization.

Accessibility

Information must be easily accessible to the users or areas that need it. It is not enough for it to be accurate and current if it is not available at the right time or if its access is restricted by unnecessary processes.

It is key to establish permissions and access levels so that each area can consult the data it needs without compromising security.

Relevance

Relevance is essential: there must be a clear reason for collecting certain data. If the information is not useful, it wastes resources and hinders effective analysis.

It is recommended to define which metrics and KPIs are priorities for each department, avoiding the accumulation of unnecessary data.

Security

Quality also means protecting information from unauthorized access, leakage or loss. This strengthens confidence in the use of data.

Encryption protocols and automated backups are critical to preventing vulnerabilities and protecting corporate reputation.

How to achieve data quality in your organization

To achieve data quality within companies, it is necessary to follow these key steps:

1. Use of specialized metrics

Before improving data, it is essential to detect existing data management problems.

Once identified and mitigated, it is possible to move towards sustainable improvements. Among the most relevant metrics are:

  • Uniqueness: avoids duplication, especially with large volumes of data.
  • Completeness: guarantees completeness for accurate analysis.
  • Accuracy: ensures that data is useful and reliable.

These metrics allow the establishment of clear standards and policies that reduce errors and improve decision-making.

2. Implement technological tools

Technology is key to optimizing data quality. There are tools designed to collect, organize and validate information automatically, which reduces the margin of error.

Solutions such as CRM or ERP make it possible to manage large volumes of data in a centralized manner. In addition, the use of artificial intelligence and machine learning helps to detect errors and make corrections in real time.

3. Continuously debug data

One of the most common mistakes is to assume that data quality is a single process. The reality is that information is constantly changing, so constant monitoring is required.

It is recommended that monthly, quarterly or semi-annual data audits be conducted and that input validation mechanisms and automatic purging processes be established.

4. Use a good data management system

To prevent storage or security problems, it is essential to have a robust and scalable system, adapted to the needs of the business.

Having strategic partners who analyze your processes and propose customized solutions can make the difference in the quality of your data.
