eDiscovery Triage — Architecture Blueprint
Production architecture blueprint for eDiscovery Triage: components, deployment patterns, cost & latency, failure modes, evaluation and governance, with sources and review dates.
Overview
This is the implementation view of eDiscovery Triage: the components it requires, where it can run, what it costs in latency and spend, how it fails, and what you must measure before putting it in front of users.
5 components to assemble, 6 documented failure modes, high implementation complexity. Every statement below comes from the canonical workflow record with its sources and review date; where the evidence does not settle a question, the page says so rather than filling the gap.
What this workflow takes in and produces
Takes in
- preserved authorized documents
- custodian and collection metadata
- review protocol
- coding decisions
- matter-level access context
Produces
- prioritized review queues
- candidate tags
- source-linked rationales
- sampling and disagreement reports
Applied to
- authorized review-set prioritization
- candidate relevance and responsiveness classification
- human-controlled privilege review preparation
Components you need to assemble
A working implementation needs 5 distinct components. Each is a build-or-buy decision in its own right.
- preservation and collection system
- deduplication and document processing
- review platform
- sampling and validation harness
- attorney review and audit log
Implementation complexity: high. This describes the integration and evaluation effort, not the difficulty of any single component.
Deployment patterns
Deployment options recorded for this workflow: managed-api, hybrid.
Topologies it has been recorded against: serverless-api, managed-container, hybrid-private-cloud. Each changes the data-residency, scaling and cost profile, so confirm the one you need against current provider documentation.
Cost and latency
- Collection, processing, hosting, validation samples, privilege review, quality control, and attorney adjudication dominate cost.
- Use risk-based prioritization without treating queue order or model confidence as a production or privilege decision.
How this workflow fails
Observed failure modes for this class of workflow. Design a check for each one before shipping, not after.
- missed responsive document
- false positive overload
- privileged material exposure
- broken chain of custody
- coding drift
- unsupported legal conclusion
Risk areas the evidence covers
- review-set recall and precision
- privilege escalation
- sampling validity
- coding consistency
- chain of custody
- attorney oversight
Proving it works before you ship
Evaluation readiness: Partial — Recall, precision, sampling, disagreement, privilege-risk, chain-of-custody, and reviewer measures are defined; matter-specific protocols and thresholds remain required.
Worked evaluation case: Attorney-supervised review-set prioritization
Prioritize an authorized review set while preserving chain of custody, sampling coverage, source traceability, and attorney control over relevance, privilege, and production.
What to measure
- responsive-document recall and precision
- validation-sample and elusion results
- privilege-risk escalation
- coding consistency and reviewer agreement
- chain-of-custody integrity and review burden
Governance and data handling
- Enforce matter-level authorization, preservation, legal hold, confidentiality, privilege, export, retention, and audit controls.
- Treat all relevance, responsiveness, and privilege signals as review aids; qualified attorneys retain legal determinations and production authority.
Implementation notes
- Preserve custodian, source, collection, processing, hash, family, version, coding, reviewer, production, and exception history.
- Use statistically defensible validation samples and monitor reviewer disagreement, category drift, rare issues, and privilege-risk cohorts.
What this blueprint does not establish
- Discovery duties, relevance, responsiveness, privilege, proportionality, and production decisions depend on the matter, jurisdiction, orders, agreements, and counsel.
- This workflow does not determine privilege, relevance, liability, discoverability, or what may be produced.
Source coverage: Partial — The Federal Rules establish civil-discovery procedure and proportionality context; ABA Formal Opinion 512 supports competent, confidential, supervised use and output review. Neither validates a triage model or resolves matter-specific privilege.
Sources reviewed 2026-07-02. Revalidate applicable rules, orders, review protocol, corpus, legal holds, coding decisions, and attorney policy for each matter.
