Build versus buy is a governance decision before it is a technology decision

MGAs often frame technology sourcing as a contest between speed and control. Vendors offer faster implementation and shared investment; internal builds promise differentiation and flexibility. Both descriptions are incomplete because the central exposure is continuing governability.

NAIC attention to third-party data and models makes the point explicit for AI-enabled decisions, while Lloyd’s guidance keeps accountability with the delegating organization. Outsourcing a capability does not outsource the need to understand its role, limitations and failure modes.

Begin with the decision being supported

A commodity document store and an appetite engine do not deserve the same ownership analysis. Leaders should assess how directly the capability shapes risk selection, how quickly it must change, whether its evidence is proprietary and how damaging interruption or opacity would be.

Where the decision is strategically distinctive, the MGA may need to own rules, data and evaluation even if a vendor supplies infrastructure. Ownership of code is less important than control of the underwriting logic and the ability to move it.

Portability is the hidden requirement

A vendor relationship is more resilient when data, configurations, decision history and interfaces can be exported in usable form. Exit rights should be tested before implementation rather than discovered during a dispute or acquisition.

Internal systems have portability risk too. A platform understood by one engineer or built on obsolete components can be less transferable than a well-governed vendor service. The relevant question is whether the organization—not an individual or supplier—can continue the capability.

The countercase: optionality has a cost

Designing every system for hypothetical replacement can slow delivery and dilute the benefit of specialized vendors. Some switching cost is rational where performance is strong and the capability is not central to underwriting advantage.

Leadership should price dependency rather than eliminate it. A replaceability plan can vary from full parallel capability to escrow, export rights, documented manual fallback or acceptance of interruption within a defined tolerance.

Govern the lifecycle

The sourcing decision should specify accountable business ownership, validation, change approval, incident response, data rights, service continuity and exit. Those responsibilities continue after procurement and should appear in operating forums.

A successful build-versus-buy decision remains rational when circumstances change. If the organization cannot explain what would cause it to switch, invest or retire the capability, it has made a purchase—not a technology strategy.
