Following Capella Day Toulouse last year, this workshop was the opportunity to share with experts about Capella, the open source model-based systems engineering tool. On the agenda: >> The Capella workbench roadmap: latest features in Capella 1.2 and next to come in the future Capella 1.3 release >> Update on the Capella add-ons and extensions: from requirements management, document generation, collaborative work, to Capella projects, libraries and dependencies storage... >> The Capella ecosystem and how you can be involved in it
