| Imerys’ Digital Transformation

In 2018, Imerys started a global digital transformation. Prior to 2018, Imerys’ previous intranet was top-down and static using legacy software. Information was hard to find and collaboration impossible. With the migration from Lotus Notes and Microsoft Office to the G Suite, Imerys looked for a tool able to reflect and support this transformation.

The goal was to design an online environment that:

  • Complemented Imerys’ newly launched digital ecosystem
  • Brought all relevant information together in one place,
  • And encouraged people to collaborate.

| Imerys and LumApps

Imerys and LumApps worked together to create a single digital workplace. This is how OneImerys was born in just under six months. This platform is the only intranet for all connected employees around the world. Fully integrated with G Suite used by Imerys, the platform simplifies access to all Group-wide content and news, social discussions and business communities. This global and unique place for employees is the go-to source for timely information and news.

In a fast-paced environment and as the company was transforming itself, Imerys needed a flexible tool, which would enable them to adapt the functions and businesses sections to mirror its new organizational set-up and create a dedicated section for all transformation news. OneImerys has successfully succeeded in enabling both vertical – top-down communication and bottom-up feedback – as well as horizontal exchanges.

Whilst Imerys was moving from a decentralized to a more centralized organization, having a single digital communications tool was paramount to ensure our transformation’s success. Two years on, our
OneImerys intranet has proven to be a solid, reliable, trustworthy and useful platform for our employees on a day-to-day basis. It has also enabled us to be timely, engaging and creative in our employee communication.

| Key Use Cases

A progressive roll-out 

Imerys aimed to build a Minimum Viable Product to develop and launch its platform in a relatively short period of time with sufficient features to satisfy early adopters and sufficiently solid foundations to continue building on. In five months, OneImerys was launched. Since then, the platform has evolved, with the addition of new features and content.


The global Life@Imerys community enables leaders to recognize some of their employees online and for employees worldwide to share some of their events and communicate with one another in a more casual way. LumApps communities give a voice to employees, with the ability to like, comment, and ask questions directly on posts.

A tool to support change management

In three years, Imerys CEO changed three times and underwent a global transformation totally restructuring its organization. OneImerys has been a key element in supporting these many changes. It is the go-to place for the CEO to express himself and get employee feedback.

Upon joining, Imerys’ new CEO, A. Dazza, has received over 70 questions from employees via the platform and his videos have been seen over 7,600 times.

Personalized content

LumApps enables Imerys to personalize its communication for each employee. With 250 locations and 268 different languages, targeted functionality is key. Employees have access to relevant, personalized and multilingual content according to their profile and location. Personalized content is based on a tag management system sourced from Workday and Google Group.
