Primary Use Case: Offline Messaging & Alerts

Background Overview

Field teams often work in areas with poor network connectivity. Without offline capabilities, important messages are lost and alerts don't reach teams. This primary use case describes offline messaging, local storage, and synchronization to ensure reliable communication.

Goals & Value

• Message Reliability: Ensure messages are delivered even without network.
• Alerting Mechanisms: Priority-based alerting for important messages.
• Priority Management: Categorize and manage message priorities.
• Seamless Sync: Automatic synchronization when network returns.

Participating Roles

• Field Staff: Receive and send messages with offline support.
• Operations: Configure offline settings and priorities.
• Sales Managers: Send important updates and alerts.
• IT Team: Maintain offline messaging infrastructure.
• System Admin: Configure sync policies and storage limits.

Primary Scenario User Story

As a field sales representative, I want to send and receive messages even without network, so that I can communicate reliably regardless of location.

Sub-scenario Details

Sub-scenario A: Offline Message Composition & Storage

• Roles & Triggers: User creates messages without network connectivity.
• Main Process:
  1. User composes messages in offline mode.
  2. Messages stored locally with metadata.
  3. Queue messages for delivery when network returns.
  4. Provide visual indicators for offline status.
• Success Criteria: Reliable local storage; clear offline status; message integrity.
• Exceptions & Risk Control: Storage limits; message corruption; local data loss.
• Metric Suggestions: Storage reliability, message integrity, offline success rate.

Sub-scenario B: Priority-based Alerting

• Roles & Triggers: Important messages require special handling.
• Main Process:
  1. Classify messages by priority and urgency.
  2. Alert users based on priority settings.
  3. Use different notification methods for different priorities.
  4. Escalate urgent messages through multiple channels.
• Success Criteria: Appropriate priority handling; effective alerting; no urgent message misses.
• Exceptions & Risk Control: Priority misclassification; alert failures; notification overload.
• Metric Suggestions: Priority accuracy, alert success rate, urgent message delivery.

Sub-scenario C: Automatic Synchronization

• Roles & Triggers: Network connectivity is restored.
• Main Process:
  1. Detect network connectivity restoration.
  2. Automatically sync queued messages.
  3. Resolve any sync conflicts.
  4. Confirm delivery to users.
• Success Criteria: Successful sync; conflict resolution; delivery confirmation.
• Exceptions & Risk Control: Sync conflicts; partial sync; delivery failures.
• Metric Suggestions: Sync success rate, conflict resolution time, delivery confirmation rate.

Sub-scenario D: Message History & Audit

• Roles & Triggers: Need to track message delivery history.
• Main Process:
  1. Maintain complete message delivery logs.
  2. Track message status (sent, delivered, read).
  3. Provide audit trail for important messages.
  4. Generate delivery reports and statistics.
• Success Criteria: Complete logs; accurate status tracking; useful audits.
• Exceptions & Risk Control: Log corruption; status inaccuracy; data retention.
• **Metric Suggestions: Log completeness, status accuracy, audit success.

Scenario-level Test Case Examples

Test Preparation: Prepare offline messaging system, sync engine, alerting tools, and audit logging.

Test Case A-1: Offline Message Storage (Positive)

• Prerequisites: User in area with no network connectivity.
• Steps:
  1. User composes and sends message offline.
  2. Message stored locally.
• Expected Results:
  • Message saved locally with pending status.
  • Visual indicator shows offline mode.
  • Message queued for delivery.

Test Case B-1: Urgent Message Delivery (Negative)

• Prerequisites: User receives urgent message.
• Steps:
  1. Urgent message sent to user.
  2. System uses high-priority alerting.
• Expected Results:
  • User receives immediate alert.
  • Message delivered via multiple channels.
  • Delivery confirmation tracked.
