Case Management is Sigma's built-in investigation workspace. When your team flags a suspicious transaction, identifies a high-risk customer, or receives an adverse media hit, Case Management gives you a structured place to investigate it — assigning ownership, tracking progress, recording decisions, and maintaining a full audit trail. Cases can be created manually from the dashboard or linked directly to records from other Sigma products: flagged transactions, AML screening results, CDD reviews, or KYC lookups. Every action taken on a case is logged automatically, giving you a compliance-ready record of how each issue was handled. ### Why it Matters Investigations are rarely simple. They involve multiple people, span days or weeks, and require documentation that can withstand regulatory scrutiny. Without a centralised system, teams rely on spreadsheets, emails, and informal handoffs — creating gaps that auditors find and regulators flag. Case Management solves this by: * **Assigning clear ownership** — every case has a responsible analyst and an optional escalation path * **Tracking status end to end** — from open through in progress to resolved or closed * **Keeping a full audit trail** — every status change, comment, reassignment, and task completion is logged with a timestamp and the user who made it * **Supporting collaboration** — analysts can comment, tag teammates, attach files, and update checklists within the case * **Enabling AI-assisted investigation** — Sigma can run an AI investigation on any case to surface relevant context and flag patterns ### When to Create a Case | Trigger | Example | | ----------------------- | ----------------------------------------------------------------------------- | | **Flagged transaction** | A transaction scoring above your fraud threshold needs manual review | | **AML hit** | A PEP or sanctions match requires investigation before a decision is recorded | | **CDD concern** | A customer's risk tier increases and a deeper review is needed | | **Regulatory request** | An authority requests documentation of how a specific customer was handled | | **Internal escalation** | A junior analyst flags an issue that needs senior review | ### Core Capabilities * **Create cases** linked to any Sigma record or standalone for general investigations * **Assign and reassign** cases to specific team members with email notifications * **Set priority and due dates** to manage workload and SLA compliance * **Track tasks** within each case as a checklist * **Comment and collaborate** with file attachments and user mentions * **Escalate** cases to senior team members when needed * **Update status** to reflect where the investigation stands * **Run AI investigation** to surface relevant context automatically * **Manage custom modules** to categorise cases beyond Sigma's default product modules Understand the case lifecycle and how to run your first investigation.
