Normalize deliberately
Prepare metadata, extracted text, natives, images, messages, and attachments around the review strategy.

Deliver with traceability
Provide inventories, exception notes, load-ready packages, validation details, and clear handoff documentation.

A controlled engagement
Five stages. One defensible record.
Every matter begins with authority and scope. Every delivery ends with documented outputs, limitations, and a clear handoff.

Authority & conflict check
Confirm the requester, legal authority, ownership or consent, matter sensitivity, and potential conflicts.
02
Scope & plan
Define questions, systems, custodians, dates, deliverables, constraints, and a proportionate technical approach.
03
Preserve & acquire
Document sources, maintain provenance, verify acquisitions, and record material exceptions or limitations.
04
Examine & validate
Apply appropriate tools and methods, test important findings, and separate observed facts from interpretation.
05
Deliver & support
Provide the agreed reports or review packages, explain the results, and support reasonable follow-up.
