Data Cleaning: an imperative for the future of your data
In a world where regulations are multiplying and environmental issues are becoming ever more pressing, Data Cleaning is now a strategic priority for organizations. It's no longer a question of simply accumulating data, but of mastering its life cycle to get the most out of it, while complying with current standards.
Eliott Mourier, Partner Data Compliance & Privacy, and Pascal Anthoine, Data Governance Director Senior Partner, share their expertise and give you the keys to a successful project in this exclusive white paper.
Mastering your data also means knowing when, where and how to clean it when it reaches the end of its lifecycle. While regulatory constraints in this area are increasingly stringent (particularly with a view to minimizing the risk of data leaks), data cleansing is also a major challenge to ensure that your data assets retain their relevance and value over time.
Data Cleaning and Data Governance: two complementary pillars for optimal data management
In an environment where data management is a major strategic challenge, data governance plays a central role. It ensures the quality of data throughout its lifecycle. Its aim is to manage, exploit, optimize, evaluate, protect, control and maintain data within the organization. This comprehensive approach ensures data reliability and compliance, while facilitating its use for analysis and decision-making.
However, the end-of-life phase of data is often overlooked in the context of data governance, even though it is crucial. Many companies focus primarily on the collection, processing and use of data, but for many of them, the stage at which this data must be archived or deleted is all too often neglected. However, compliance and data protection issues are just as important, if not more so, at this stage. Indeed, inappropriate data management at the end of the cycle can expose the company to legal and financial risks, as well as damage its image.
Data end-of-life management: a strategic lever for risk reduction
This is where Data Cleaning comes in: it doesn't just involve cleaning up erroneous or obsolete data, but also ensures that it complies with current regulations, in particular the RGPD (General Data Protection Regulation). Data Cleaning complements Data Governanceensures that only relevant, up-to-date and compliant data is retained, while data that no longer meets compliance criteria or represents no strategic potential is effectively deleted or archived.
Far from being a simple operational choice, end-of-life data management is actually a strategic lever available to companies to reduce the risk of non-compliance, improve efficiency and ensure the sustainability of corporate operations. It also makes it possible to minimize storage and data management costs, while ensuring that the company complies with current legal and ethical standards.
