Iceberg Tribe Advisory • AI Decision Architecture (Build & Buy)
Every piece here audits an irreversible decision an institution faces across the five enterprise AI gates — whether commissioning an in-house build, approving an internal go-live, or procuring from an external vendor. Not trending topics, not a content calendar.
When an audit reaches an enforceable standard — a warranty review for vendor contracts, or an Internal Build Checklist and Initiative Register for systems built in-house — it points directly to Instruments: runnable diagnostic tools, not another conceptual post.

Irreversible milestones across the enterprise AI decision lifecycle — both in-house builds and vendor procurement
“Because vendor and consultant build-or-buy models omit opposite cost categories by design, the buy-versus-build decision depends on whose arithmetic authored the total cost of ownership.”
“Because whoever builds the cost model has a stake in the answer — and so does everyone else positioned to check it.”
