The people who lead every engagement.
Every Sustenra engagement is led by a principal with direct experience inside the systems being assessed. The person accountable for the answer is the person doing the work.
The principal-led model
Senior leadership present throughout the engagement, not just at the start.
Sustenra operates on a principal-led model. Every engagement is scoped and led by one of the three principals from start to finish. Supporting work may involve additional capacity, but the principal responsible for the assessment remains accountable for the answer at every stage.
This matters because governance advisory depends on the quality of the judgement being applied. Senior expertise at Sustenra is not a selling point. It is the delivery mechanism.
