Where ISO 19650 governs how information is managed during design and construction, ISO 55000 governs the much longer asset-management phase that follows - aligning budgets, risk, and performance targets across an entire portfolio of buildings, not just a single project. A well-structured Asset Information Model (AIM) handed over at the end of a project is what lets an ISO 55000-compliant organization actually use that data operationally.
