# Use Case

> Case Management for cross-team financial crime investigations

### The Challenge

<div className="bg-white dark:bg-gray-800 p-6 rounded-lg shadow border-l-4 border-red-500 mb-8">
  <p className="text-gray-700 dark:text-gray-300">
    A regulated institution receives{" "}
    <span className="font-bold">high volumes of fraud and compliance alerts</span>{" "}
    across Transaction Monitoring, AML screening, CDD reviews, and KYC checks.
    Investigations are handled by different teams, often across spreadsheets,
    email threads, and chat tools.
  </p>

  <p className="text-gray-700 dark:text-gray-300 mt-2">
    Without a structured investigation workflow, institutions risk missed SLAs,
    inconsistent decision records, weak audit evidence, and delayed escalations
    during high-risk incidents.
  </p>
</div>

### Our Solution

<div className="bg-blue-50 dark:bg-gray-900 p-6 rounded-lg shadow-md mb-8">
  <p className="dark:text-gray-200">
    Sigma Case Management provides a single investigation workspace where teams
    can triage, assign, investigate, escalate, and close cases with a complete
    audit trail.
  </p>

  {" "}

  <div className="mt-4 space-y-2">
    <li className="flex items-start">
      <span className="text-blue-600 mr-2">→</span>
      <span>One queue for cases created from any Sigma product or manually</span>
    </li>

    <li className="flex items-start">
      <span className="text-blue-600 mr-2">→</span>
      <span>Clear ownership with assignee, priority, due date, and escalation path</span>
    </li>

    <li className="flex items-start">
      <span className="text-blue-600 mr-2">→</span>
      <span>Collaborative investigation using tasks, comments, mentions, and attachments</span>
    </li>

    <li className="flex items-start">
      <span className="text-blue-600 mr-2">→</span>
      <span>AI-assisted investigation and immutable activity history for compliance reviews</span>
    </li>
  </div>

  <p className="mt-4">
    Sigma helps compliance and operations teams move from fragmented incident
    handling to a repeatable, regulator-ready investigation process.

### How It Works

<div className="relative bg-white dark:bg-gray-800 p-6 rounded-lg shadow-md mb-8">
  <div className="absolute top-0 right-0 w-24 h-24 bg-blue-100 rounded-bl-full -z-10" />

  <div className="flex flex-col space-y-6">
    <div className="flex items-center">
      <div className="bg-blue-600 text-white rounded-full w-8 h-8 flex items-center justify-center font-bold mr-4">
        1
      </div>

      <p>Analyst opens a case from a flagged transaction, AML hit, CDD review, KYC check, or the dashboard</p>
    </div>

    <div className="flex items-center">
      <div className="bg-blue-600 text-white rounded-full w-8 h-8 flex items-center justify-center font-bold mr-4">
        2
      </div>

      <p>Case is assigned with priority and due date, then routed to the responsible investigator</p>
    </div>

    <div className="flex items-center">
      <div className="bg-blue-600 text-white rounded-full w-8 h-8 flex items-center justify-center font-bold mr-4">
        3
      </div>

      <p>Investigator works tasks, adds evidence, collaborates in comments, and runs AI investigation when needed</p>
    </div>

    <div className="flex items-center">
      <div className="bg-blue-600 text-white rounded-full w-8 h-8 flex items-center justify-center font-bold mr-4">
        4
      </div>

      <p>Case is escalated to senior reviewers when risk or authority thresholds are met</p>
    </div>

    <div className="flex items-center">
      <div className="bg-blue-600 text-white rounded-full w-8 h-8 flex items-center justify-center font-bold mr-4">
        5
      </div>

      <p>Final decision is recorded, case is resolved and closed, and the full audit log remains available</p>
    </div>
  </div>
</div>
