Salesforce fits investigations where subjects, events, and evidence references must connect to CRM identities with strong API integration. Its Flow and Apex automation plus REST, Bulk, and streaming APIs support multi-step orchestration while RBAC, sharing rules, and field-level security enforce scoped access.
Implementation pitfalls that show up across investigation platforms
Many selection failures originate in schema and governance mismatches rather than missing UI features. Automation and API surfaces also create failure modes when mappings and workflow logic are configured without a test harness or standards.
The pitfalls below map to concrete tool behaviors and configuration constraints identified across these platforms.
Underestimating schema mapping effort for new evidence sources
CaseFleet, Everlaw, Relativity, Nuix, and OpenText eDiscovery all rely on schema-driven modeling and processing, so new evidence types trigger mapping work that can slow rollout. Build a schema mapping plan first, then prototype evidence intake and record creation before scaling through multiple cases.
Treating automation rules as configuration instead of executable governance
CaseFleet workflow automation requires careful configuration to avoid rigid workflows, and Everlaw automation needs careful design to prevent misaligned codes and fields. Use a standards-backed configuration workflow so task routing, status checks, and coding steps stay aligned with the data model.
Assuming API automation will succeed without orchestration and test coverage
Relativity and Salesforce API-driven workflows need disciplined data modeling, and Nuix API-driven workflow control needs strong test coverage to avoid inconsistent outputs. Put integration tests around provisioning, ingest, and export flows before turning on high-throughput automation.
Mixing enrichment governance with investigation governance inside one system
Clearbit governance centers on API key controls and account activity rather than granular in-tool RBAC, so it should not be treated as the primary defensibility layer for evidence changes. Use Clearbit for schema-stable enrichment results, then push those fields into an investigation system like CaseFleet, Everlaw, or Salesforce that enforces RBAC and audit logging.
Overbuilding custom automation when built-in workflow configuration can cover case lifecycle
OpenText eDiscovery and iManage both depend on workflow configuration and admin mapping between schemas and lifecycle steps, so excessive custom hooks increase operational overhead. Start with configurable workflow mapping, then add API-driven custom logic only where repeatable configuration cannot express the required routing or record operations.
