Concretely?

Schmidt Groupe operates approximately 160 micro IT applications. The IT department sought to better define the elements to be mapped within this specific application landscape and trusted Oresys to lead the initiative.
Oresys suggested an iterative approach to IT system mapping. Initially, the working group conducted workshops to produce a first version, configured within the selected tool. In the second phase, the group refined the mapping to a more technical version, which was then validated by the sponsors during a dedicated presentation. Oresys concluded the engagement by delivering a final document summarizing Schmidt Groupe’s mapping strategy.
Oresys brought value through its expertise in IT architecture and urban planning, as well as its knowledge of market-leading mapping solutions. Leveraging an innovative, tool-supported “Lean Mapping” approach tailored to client needs, Oresys successfully delivered an operational mapping framework within less than three months for the initial scope.

GRDF’s Eastern Region is aiming to improve customer retention and has launched a loyalty program driven by its field technicians, who play a key role in customer engagement due to their direct contact with end users.
Oresys supported the initiative by working directly with technicians in the field, providing coaching sessions to raise awareness on retention strategies. In parallel, Oresys assisted managers in promoting a client loyalty-oriented culture and implementing both individual and collective engagement rituals.
Oresys brought valuable insights thanks to its deep understanding of GRDF’s operational context and its national rentention program, as well as its expertise in change management and experience in supporting managerial teams. A tailored approach was designed for each site, adapted to the specific needs and characteristics of GRDF’s technician population.

The Eurometropolis of Strasbourg trusted Oresys to support its IT systems urbanization initiative.
Oresys worked with three departments to develop their 5-year IT Master Plans:

Human Resources Department: Oresys first conducted a diagnostic of the existing HR IS and assessed its ability to meet future challenges, such as HR performance management and tools for managers and employees. A 5-year urbanization target was then defined, along with a project roadmap to achieve it.

Water & Sanitation Services: Oresys defined a 5-year IT target focused on improving network maintenance and enhancing the customer billing portal.

Public Procurement Department: The urbanization process helped identify opportunities for process automation to reduce the administrative burden on staff.

Oresys leveraged its long-standing expertise in IT urbanization and its deep understanding of local government operations to deliver a pragmatic approach aligned with business needs.

Within the Direction of Technology and Innovation (DTI) at DGAC, the high standards required for air transport safety demand strong managerial capabilities from both operational teams and leadership.
In this context, Oresys supported the DTI along two key dimensions:

Clarifying the objectives of the managerial transformation
Assessing the current organizational landscape: identifying strengths and challenges, internal convictions, and the strategic need for transformation

This approach enabled the co-construction of a managerial framework for the DTI, defining expected roles and competencies, and formalizing a skills development plan for managers through a dedicated training pathway and the creation of a managerial community.
Oresys helped bring coherence to the transformation by aligning existing concepts and initiatives with the strategic priorities of the DTI.

The Departmental Council of Mayenne is actively developing and deploying its data strategy. The roadmap is structured around four key pillars: data culture, strategy, architecture, and governance.

Oresys supported the department across several initiatives, including:

Promoting and democratizing the use of Open Data:
Defining a roadmap for data literacy
Organizing awareness workshops during the “Data Month”
Designing and facilitating an Open Data hackathon, featuring experiments with OCR tools and generative AI

Raising awareness of AI:
Leading a seminar on artificial intelligence for all DTI staff

Decision-making support:
Designing and applying a methodology for indicator scoping to help business departments build effective dashboards

Data governance:
Formalizing a data governance policy for the organization

Oresys brought its expertise in Data, AI, and Enterprise Architecture, combined with a strong understanding of both IT and business contexts within local authorities, to support the department across all aspects of its data-related challenges.

Safran Helicopter Engines, part of the Safran Group, launched the deployment of oSmoz—a project management system based on the Planisware tool—integrating new project management processes. The objective: increasing accountability among program, project, and work package managers regarding planning data, progress tracking, costs, and remaining work.
Oresys supported the project team by providing expertise in configuration assistance, managing complex procedures for updating key data repositories, and post-deployment user support.
The implementation of a new operating model for the support team, the design of dedicated tools, and the systematic capitalization of resolved issues helped improve efficiency and responsiveness in handling requests. This also enabled the project team to better manage increasing demands and enhance the reliability of project performance reporting.
