A complex data asset to manage!

Only 9% of French companies claim to use between 71% and 80% of their data assets. Organisations need to be able to store and preserve data so that it is easily accessible, available and protected against the risks of theft, loss or damage.

Data cleansing is a crucial step in this process, as inaccurate or obsolete data can distort analyses and lead to incorrect strategic decisions. By eliminating duplicates, correcting errors and standardising formats, companies can ensure that their data is not only reliable, but also usable. This enables better decision-making, more precise targeting of marketing campaigns and optimisation of resources. By investing in data cleansing tools, companies not only improve the quality of their information, but also their ability to innovate and adapt to market demands.

At the same time, implementing good data management practices is essential to guarantee the long-term integrity of the data. This includes data governance policies, team training and the use of appropriate technologies. A corporate culture focused on data quality can transform an organisation’s information potential, enabling it to stand out in an increasingly competitive environment. Ultimately, data cleansing is not just a technical operation, but a strategic lever for business success.

The benefits of Data Cleaning

Data cleansing is an essential step for any organisation wishing to optimise its information assets. It ensures that data is ready to be used for accurate analysis and efficient operations.

Investing in data cleansing is a strategic choice that offers significant benefits, both operationally and economically. It’s an investment that not only supports growth and innovation, but also establishes a solid foundation for responsible and effective data exploitation.

More informed decision-making

How can you set up data cleansing tools?

Data cleaning is the process of identifying, correcting and eliminating errors, inconsistencies and duplications within a data set. This process ensures the quality, accuracy and reliability of the information, making it easier to use for informed analysis and decision-making. Data cleansing includes various techniques, such as data normalisation, enrichment and validation, and is essential for any organisation seeking to maximise the value of its information assets. By ensuring that data is clean and reliable, data cleansing helps to improve operational efficiency and increase confidence in the results of analysis.

1st advice

Steps to take to clean up your data

Effective cleaning is not just a random process; it requires a structured and methodical approach:

  1. Prepare the audit: set up the cleaning process by activating the concepts to be searched for
  2. Automate: launch and automate audits on the volumes of data to be analysed
  3. Validate actions: call on the business referents to decide on the actions to be taken on the data sources reported
  4. Clean / Archive: archive and delete data sources
2nd advice

Data cleaning tools: points to watch out for!

When it comes to data cleaning tools, there are a number of points to bear in mind if the process is to be effective. First of all, it is crucial to choose tools that are adapted to the specific needs of the organisation, whether they be dedicated software or solutions integrated within other systems.

Secondly, it is important to consider how easy these tools are to use, as a user-friendly interface makes it easier for teams to adopt them. In addition, it is important to ensure that the tools offer the full functional scope required for quality assurance, such as duplicate detection, data validation and standardisation, to ensure complete coverage of cleansing needs.

Finally, the ability to integrate with other data management systems – such as MDM – is essential to ensure a smooth workflow. By taking these elements into account, organisations can put in place an effective and sustainable data cleaning process.
