We chose DataGalaxy to provide us with a common repository that will enable us to better understand data, to know where it comes from, how it is transformed, how it is made available, and all this through a collaborative platform that will enable us to create, emulate, share, and ensure that we have a common vocabulary across the company’s data.

Project background and strategic challenges

Following a diagnosis of their customer relationship management, VIASANTÉ’s general management initiated a transformation program with a strategy of being resolutely customer-oriented.

The challenge set for 2019 was to deliver memorable customer experience to achieve loyalty objectives. This translated into a data-driven approach, aimed at improving their knowledge of the customer, and a customer-centric approach, aimed at improving customer journeys and associated resources.

This approach led them to define a governance framework based on four axes:

  1. Organize around data by identifying the players, their roles and responsibilities
  2. Have a common language defined in simple terms to ensure that it is easily understood
  3. Guarantee data quality to meet business and regulatory requirements and identify the data life cycle from source to use
  4. Enable data to be shared and disseminated in a controlled manner

The Data Knowledge Catalog implementation process

During their search for a data catalog, DataGalaxy was chosen for several reasons:

  1. Its agility an easy-to-learn platform for business and IS users
  2. The tool met their needs both functionally and technically
  3. The support provided during implementation was comprehensive

DataGalaxy was implemented in several stages, starting with a validation of priority use cases and their objectives with business teams. Next:

  • Eleven reference data owners were appointed from several teams including customer relations, sales, contract management, and services
    Data stewards (mainly business users) were the first users to feed the Business Glossary with definitions validated by the data owners
  • Technical teams were then put in place with a technical referent appointed to ensure documentation of the Data Dictionary 
  • Specific business and IT monitoring committees were set up to coordinate documentation work according to needs and current projects
  • “Data breakfasts” and ongoing trainings have been organized to encourage adoption of the tool and raise awareness of data-related issues
