Define the buying problem

Name the workflow stage, users, return types, software, document sources, volume range, review standard, security needs, and implementation constraints. Avoid buying a broad platform to solve an undefined bottleneck.

Rank must-have, useful, and out-of-scope capabilities before vendor demonstrations.

Qualify every claim

Ask whether a capability is generally available, plan-specific, integration-dependent, in pilot, custom, or planned. Request current documentation and a demonstration in the relevant product and environment.

Treat testimonials and vendor benchmarks as hypotheses until the methodology and applicability are clear.

Run representative tests

Include easy, complex, incomplete, contradictory, corrected, unsupported, and security-sensitive scenarios. Evaluate evidence traceability, exception quality, reviewer control, integration behavior, and fallback—not only successful field population.

Agree in advance on acceptance criteria and who will judge them.

Review governance and security

Map data flows, subprocessors, model use, access, retention, training use, exports, deletion, incident handling, support access, and change notification. Fit the service into the firm's written information security program.

Use least privilege and a limited pilot before granting broad production access.

Evaluate total implementation

Include configuration, migration, workflow redesign, training, review effort, exception handling, support, contract terms, exit, and internal ownership. Pricing alone does not describe operational cost.

Document the decision, limitations, and re-evaluation date. Product scope changes quickly.
