Independent Assurance
Independent assurance that gives sponsors, SROs and investment boards confidence in programme delivery. When programmes become complex, high-profile or strategically important, sponsors need more than progress updates. They need an independent view of delivery health, governance, risk and whether the programme remains on track. Three Oaks works alongside sponsors, SROs and investment boards to provide clear, evidence-based insight that strengthens decision-making while leaving accountability with the delivery team.
When Independent assurance Adds Value
Independent Assurance is most valuable when programmes are already in motion but confidence is weakening.
It is used where senior leaders need an independent, experienced view of delivery health, governance strength, and risk exposure — without changing ownership or taking control of delivery.
This service is typically engaged when:
• Delivery confidence has reduced but the programme must continue
• Governance exists but is not providing clear decision support
• Risks are being managed locally but not surfaced coherently
• Sponsors or investment boards need objective challenge
• Delivery teams require clarity, not additional management layers
Independent Assurance strengthens oversight, sharpens governance and restores confidence while leaving accountability where it belongs.
