On April 13, at 11:00 AM EDT (5:00 PM CEST), Alex Fournié, MBSE Product Owner at Obeo, will present a webinar organized by INCOSE as part of its "SE Lab Demo Day" series.  Title: Scaling collaborative MBSE projects without complex setup, with Cloud for Capella Abstract: Deploying and maintaining collaborative MBSE environments can be complex and time-consuming, often slowing down project initiation and limiting effective collaboration across teams. This webinar introduces Cloud for Capella, a solution designed by Obeo to address these challenges. Cloud for Capella is a Software as a Service (SaaS) solution that provides a secure, pre-configured, and ready-to-use MBSE environment, accessible without any local installation. It enables immediate collaboration on the design and architecture of complex systems, helping teams streamline their engineering processes from day one. With an environment already installed and configured by Obeo, authorized users can start working dir...

Obeo is honored to sponsor the upcoming MBSE Summit 2026, organized by the INCOSE Indian Chapter in Chennai, the 24th and 25th of April. This year the event topic will be "Engineering the Future: Mobility & Next-Generation Industries". During this event, Ashutosh Sonawane, from Obeo, will deliver a talk titled "Open-Source MBSE in Action: Driving Adoption, Collaboration, and Scalability in Systems Engineering". To maintain a global and coherent vision of complex systems, Model-Based Systems Engineering (MBSE) offers a powerful alternative to traditional document-based approaches. By relying on formal digital models to specify, design, analyze, and verify systems, MBSE enables more effective decision-making, improves collaboration across stakeholders, enhances understanding of system complexity, and facilitates tool integration. In this talk, Ashutosh will present Obeo's open-source strategy to support and accelerate the adoption of MBSE at scale. He wi...

Environmental Trade-offs into MBSE: An Application of Ecodesign for Capella for System Architects Watch the replay of this webinar held on February 12th, 2026.   This webinar shows how environmental analysis can be brought into the MBSE workflow using the Ecodesign for Capella add-on. Traditionally, life cycle and environmental trade-off assessments are done outside system models and too late to influence architecture. The session explains how architects can use Capella with built-in environmental criteria and trade-off features to assess impacts within their usual modeling environment. A practical use case on a drone inspection product line illustrates the approach, its benefits, and lessons learned. ***  Presented by: Thibault MontigaudLGM Thibault Montigaud joined LGM in 2016 after graduating with a degree in Industrial Risk Management from INSA Centre Val de Loire in Bourges and a degree in Automation from the University of Orléans.
