Utilities operate infrastructure with lifecycles measured in decades against software and data platforms that are replaced several times within a single asset's life. Any system that models the asset base is therefore guaranteed to be migrated repeatedly, and the asset data will outlive every system that has ever held it.
Programmes that do not plan for this treat asset data as an application concern. The result is that each migration loses fidelity — history truncated, condition assessments abbreviated, provenance dropped — and the organisation's understanding of its own network degrades a little with every replacement.
