What has to change underneath the announcement

New structures get announced, new language gets adopted, and underneath all of it the same work is done the same way by the same people on the same incentives. The programme closes on time and nothing material changes.

Wrenwell designs transformation around the mechanics of how work actually gets done: who decides, what they are measured on, where information moves and where it stalls. Structure follows from that, because a reorganisation that leaves decision rights untouched is a reorganisation that changes nothing.

Wrenwell works directly with executive teams on the operating model, structure and ways of working, and stays close enough to delivery to see whether the change is landing. What gets measured is what people do differently three months later. That is harder to establish than whether the milestones closed.

Transformation design

  • Operating Model Design — Structure, accountabilities, decision rights and governance aligned to what the strategy actually requires, which is rarely what the current org chart reflects. The design is tested against real scenarios before anyone announces it.
  • Target State & Roadmap — A sequenced path the organisation can absorb without breaking business as usual. What will get worse before it gets better, and for how long, is set out before the work starts. Sponsors surprised by that halfway through tend to reverse course, and reversing costs more than the dip would have cost.
  • Ways of Working — How decisions, work and information move through the organisation, redesigned where it matters and deliberately left alone where it does not.

Transformation delivery

  • Executive Alignment & Sponsorship — Disagreement at the executive level is surfaced early, because unresolved dissent at the top reappears as passive resistance three layers down. Sponsorship is something you build, and it decays if nobody maintains it.
  • Capability Uplift — Internal capability built during the engagement, so the change survives the exit. The work happens alongside your people, in the same meetings and on the same artefacts.
  • Adoption & Embedding — Measures that track what people actually do, paired with the governance to act when adoption stalls. What evidence would show the change has not landed is agreed in advance, because agreeing that afterwards is impossible.

How an engagement runs

  • Diagnose — Establish how the organisation currently operates in practice and where that diverges from what the strategy requires.
  • Design — Build the target operating model and a sequence the organisation can realistically absorb.
  • Mobilise — Put governance, sponsorship, and delivery capability in place before large-scale change begins.
  • Embed — Watch what people actually do, and correct where the change is not holding.

What prompts the call

  • A transformation is formally on track but nothing observable has changed.
  • A new operating model has been designed and nobody owns making it real.
  • An executive team has inherited a transformation someone else scoped.

Where this has been done. A statutory insurer carried an operating model change underneath a multi-year platform replacement, and an international retailer rebuilt its financial processes across a global estate against a fixed regulatory date. Read the case studies

What operating model work runs into

The APS Strategic Commissioning Framework, the Victorian response to the Silver Review, ISO 37000 for governance and accountability, TOGAF and the BIZBOK Guide on the architecture side, and the DTA’s AI accountability requirements are what operating model work runs into before the design is finished.

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.
