The goal is not to centralise everything, but to reduce friction: shared standards, smart automation and self-service that let teams work autonomously without reinventing the same solutions over and over. Common building blocks are CI/CD, infrastructure as code, observability and golden paths.
The platforms that succeed are treated as products — with users, feedback loops and a roadmap — not as IT projects that get ”done”. We've written more about this in Plattform som produkt (in Swedish).
