I. The governance gap
A $500m capital project is overseen by a board investment committee with quarterly stage gates, independent quantity surveyors, and binding cost discipline. A $500m transformation programme — cloud migration, ERP replacement, AI deployment — is typically overseen by a steering committee of internal executives, advised by the same systems integrator delivering the work.
McKinsey's long-running research on transformation outcomes is consistent: roughly 70 percent of large transformations fail to deliver their business case. BCG and HBR research arrives at similar figures. The root cause is not technical execution; it is the absence of independent commercial governance.
II. Four governance positions worth installing
We advise sponsors to install four governance positions, modelled on capital project discipline, before any transformation programme exceeds $50m in committed spend.
- Independent commercial review
A quarterly independent commercial review, structurally separate from the implementation partner, reporting directly to the sponsor and audit committee.
- Stage-gated funding
Funding released against pre-agreed value milestones, not elapsed time or percentage complete. This single mechanism eliminates the majority of overrun risk.
- Independent benefits tracking
Business case benefits tracked by a function independent of the programme. Self-reported benefits are systematically optimistic.
- Change-control commercials
Pre-agreed unit economics for change requests, eliminating the renegotiation premium that integrators apply mid-programme.
III. Why systems integrators do not provide this
Systems integrators are commercially conflicted as governance providers. Their revenue is a function of programme scope and duration; their incentive is not aligned with disciplined value capture. This is not a criticism of integrators — it is structural. Boards should not expect the institution delivering the work to also govern its commercial terms.
Independent commercial governance is a small fraction of programme cost — typically 0.5 to 1.5 percent — and consistently returns multiples of that investment in avoided overrun and captured value.
IV. The institutional shift required
The shift required is cultural before it is procedural. Boards must treat transformation as a capital allocation decision, not an IT initiative. CFOs must extend their capital discipline to operating spend at this scale. And sponsors must accept independent commercial scrutiny as a feature of institutional rigour, not a vote of no confidence.
