Platform replacement, migration and digitised ways of working, from business case through to embedded operation.
The money goes to the visible layer — new platforms, new interfaces, new vocabulary — while the operation underneath keeps working the way it always has. The technology lands and the benefit does not, because nobody changed the process the technology was supposed to serve.
Wrenwell starts from one question and keeps returning to it: what will this let the organisation do that it cannot do today? Everything else follows. If a business case cannot answer that in operational terms, the problem is with the case itself, and it’s cheaper to find that out before procurement than after go-live.
Wrenwell leads digital change from business case through to embedded operation: platform replacements, system and data migrations, and digitised ways of working. Wrenwell also acts independently where an organisation needs scrutiny of a vendor, an integrator, or its own optimism about a go-live date.
The Digital Service Standard and the DTA assurance framework, Victoria’s Gateway, ISO/IEC 25010 and the ISO/IEC/IEEE 29119 test series, ISO/IEC 42001 and 42006 where AI is involved, and CPS 230 for APRA-regulated clients are what a platform replacement gets measured against. No published standard covers the migration reconciliation method itself.
All five areas are set out in one place, with sources and dates, on the standards and obligations page. It was last checked in September 2026.
