From InnerSource To Open Source: Building a Dual-Focused OSPO in a Tradition...
Talkat Open Source Summit Japan + AI_dev: Open Source GenAI & ML Summit + Automotive Linux Summit 2025 · 2025-12-08..12-10·
summary
Mitsubishi Electric launches an OSPO in April 2025 that runs dual InnerSource and Open Source programs, claims a KPI to cut development lead time by up to 50%, and already grows 900 engineers on GitHub and 1,500 Microsoft Teams members using GitHub Enterprise plus GitHub Copilot with an aggregated RAG target in Copilot Spaces to turn issues and docs into a searchable knowledge base. Projects include Serendi design system, MELA Rosu driver, and Pela LCA tool, and the IVCM model reframes value as challenge→approach→implementation sharing rather than code only.
