Independent external challenge prevents the "fox watching the henhouse" dynamic by removing internal pressure to suppress risks. External experts force accountable leaders to respond to independent review findings, creating a healthy tension that encourages early identification and resolution of problems rather than concealment.
When governance relies solely on internal assurance, decision-makers face an inherent conflict of interest: those most accountable for results are also those evaluating whether risks exist. This dynamic often leads to risk suppression rather than risk management. Independent external challenge breaks this cycle by introducing an impartial perspective that cannot be influenced by internal politics or performance pressure.
The power of independent challenge lies in its structural inevitability. External reviewers answer to different stakeholders and operate under different incentives than internal teams. This means accountability leaders cannot dismiss or ignore findings as easily as they might dismiss internal concerns. The tension created—where external findings demand response and cannot be silenced—actually improves governance rather than hindering it.
As detailed in this episode of Beyond The Plan, this principle has been embedded in major infrastructure frameworks. The New South Wales Investor Assurance Framework, created in 2012, relies heavily on independent expert challenge as a core governance control. Projects at different risk tiers—from quarter-million-dollar programs to $200 million initiatives—all require proportionate external review to ensure risks surface before failure becomes inevitable.
"Governance always precede delivery failure. You can tell a project that's going to fail before it's even started."

Garaway began her career in defence, where she developed deep expertise in robust governance frameworks and risk management across large-scale infrastructure and complex programs. She specializes in how organizational structures enable or prevent project delivery success, and has worked extensively with government frameworks designed to surface risks early through independent challenge.
The absence of independent challenge doesn't just allow risks to hide—it fundamentally changes organizational behavior. When teams know their concerns will be heard by external, neutral parties, they escalate more readily and speak more candidly. This transparency cascades upward, ensuring leadership cannot remain insulated from emerging problems. The governance structure itself becomes a delivery enabler rather than a box-ticking exercise.
To explore how this principle applies across different project scales and why internal assurance fails even with good intentions, listen to the full conversation on Listenly.
When risks are raised but ignored repeatedly, as happened in RoboDebt and Queensland Health, teams eventually stop escalating. The absence of sponsor accountability and responsive governance removes the incentive to voice concerns.
In early drift, sponsors become progressively absent, delegations increase with misaligned views, project teams reduce detailed updates, and scope creep occurs—a gradual deterioration that erodes governance control over time.
The false start occurs at project beginning when scope documents are not signed off by stakeholders yet work begins anyway, budgets await approval, and governance structures are not yet formally established.
