Ministry of Ecological Transition: managing the communication of 8 ministries in project mode
In 2018, the communication department of the Ministry of Ecological Transition began an ambitious transformation: moving from an organization in silos to a collaborative operation in project mode. With more than 100 users from various professions and the responsibility to coordinate 8 ministries, the challenge was significant. Wimi has enabled this transition by offering a sovereign, secure solution that is perfectly adapted to the needs of the public administration.

“Wimi is a solution perfectly suited to collaboration in project mode. Its ease of handling and the flexibility offered according to uses convinced us. Covid-19 and the periods of teleworking have only amplified the need for such a solution to maintain exchanges and continue our projects.”

What is the Ministry of Ecological Transition?

- Complex coordination: Manage the communication of 8 ministries simultaneously with limited visibility on the progress of projects
- User adoption: Need for a simple solution to guarantee the adherence of all, regardless of their digital appetite
