SITES guided its digital transformation by defining a new "ERP + Satellite" architecture to unify fragmented operations and secure its high-precision nuclear engineering services.
SITES is an independent engineering company, leader in structural health monitoring for nuclear power plants and complex infrastructure. Despite high-tech missions, SITES operated with a low digital maturity, relying on manual data entry and fragmented tools. Stratos was mandated to define a digital roadmap that would modernize their infrastructure without compromising the specificity of nuclear safety processes. The resulting "ERP + Satellite" strategy digitized workforce management for 450 employees and automated billing for 3,500 annual invoices.
SITES ensures the longevity and safety of critical infrastructure. Their expansion led to operational silos where workforce management was handled via Excel, requiring 1.5 days of manual entry per week across various agencies. Radiopro (radiation protection) tracking was also managed in disconnected documents, creating potential compliance risks in a highly regulated environment.
"Stratos accurately diagnosed the limits of our current tools. Their distinction between Core ERP and Satellite applications provided the clarity we needed to modernize."
Thibault Gouache Directeur Général, SITES
The primary challenge was the lack of a structured operational backbone. Operational data was disconnected from financial flows, making it impossible to automate inter-company management or gain real-time visibility into project-level profitability. Furthermore, the specialized nature of nuclear engineering required that any new system maintain strict ISO and Radiopro compliance, which standard ERPs could not handle natively.
Stratos conducted a deep maturity audit through interviews across Finance, HR, and Operations. We benchmarked SITES against market competitors and designed a modular "Core vs. Satellite" architecture. This plan centralized core business functions into a unified ERP while delegating specialized safety and technical processes to dedicated "Best of Breed" tools (Satellites).
By defining a Year 1 roadmap focused on immediate compliance and billing wins, Stratos ensured that the digital transformation provided immediate ROI while building a scalable foundation for future AI integrations via AWS Bedrock.
The implementation of the roadmap secured SITES' operational and technical harmonization. Financial transparency was established through automated billing and unified timesheets, eliminating days of manual administrative work and reducing human error in project tracking.
By separating core financial tools from technical safety applications, SITES maintained its industry-leading compliance standards while gaining the agility of a modern, data-driven enterprise. The company is now equipped to integrate advanced structural analysis tools into a cohesive digital ecosystem.
