Test Alternatives Against the Due-Diligence Workflow
For due diligence and high-volume contract analysis, the relevant question is not simply whether a platform can identify clauses. The team should map the review from data-room intake through categorisation, issue identification, escalation, reporting and final verification. A useful pilot should include documents that represent the variety and quality of files the team normally receives, including inconsistent naming, scanned material or unusual drafting where these are part of the real workload. Reviewers can then compare how much manual checking remains, whether the output can be traced back to the underlying document, and whether the reporting format supports the transaction team. This creates a more realistic basis for comparing Luminance with alternative products.
Governance Should Be Evaluated Alongside Review Speed
A faster review process has limited value if the team cannot explain how data is handled, who can access a matter or how outputs are checked before they influence legal decisions. Procurement should therefore bring security, confidentiality, access controls, retention, export and vendor-management questions into the same evaluation as document analysis. Teams should also identify where human review is mandatory and how exceptions or uncertain outputs are escalated. The resulting decision record can distinguish product capability from organizational readiness. That distinction is especially important for firms serving enterprise clients, because the client's own information-security or outside-counsel requirements may affect which implementation model is acceptable even when several tools perform well in a demonstration.
