🧪 Test Mode vs Production Mode

Test Mode (TAT_TEST_MODE=true):

Purpose: Fast testing during development

Behavior:

• ✅ 1 hour = 1 minute
• ✅ 6-hour TAT = 6 minutes
• ✅ Purple "TEST MODE" badge shown
• ✅ Note: "Test mode active (1 hour = 1 minute)"
• ✅ All times are in working time (no weekend skip)

Example Alert (Test Mode):

⏳ Reminder 1 - 50% TAT Threshold      [WARNING] [TEST MODE]

Allocated: 6h | Elapsed: 3.0h

🎯 Key Benefits of Enhanced Display

1. Full Transparency

Users see exactly:

• How much time was allocated
• How much was used when alert fired
• How much was remaining
• When it's due

2. Context Awareness

• Test mode clearly indicated
• Color-coded by severity
• Badge shows warning vs breach

3. Actionable Information

• "Remaining: 2.5h" → Approver knows they have 2.5h left
• "Due by: Oct 7 at 6 PM" → Clear deadline
• "Elapsed: 6h" → Understand how long it's been

4. Confusion Prevention

• Test mode badge prevents misunderstanding
• Note explains "1 hour = 1 minute" in test mode
• Clear visual distinction from production

🧪 Testing Workflow

Step 1: Enable Detailed Logging

In Re_Backend/.env:

TAT_TEST_MODE=true
LOG_LEVEL=debug

Step 2: Create Test Request

• TAT: 6 hours
• Priority: Standard or Express
• Submit request

Step 3: Watch Alerts Populate

At 3 minutes (50%):

⏳ Reminder 1 - 50% TAT Threshold [WARNING] [TEST MODE]

Allocated: 6h  | Elapsed: 3.0h
Remaining: 3.0h | Due by: Today 2:06 PM

Note: Test mode active (1 hour = 1 minute)

At 4.5 minutes (75%):

⚠️ Reminder 2 - 75% TAT Threshold [WARNING] [TEST MODE]

Allocated: 6h  | Elapsed: 4.5h
Remaining: 1.5h | Due by: Today 2:06 PM

Note: Test mode active (1 hour = 1 minute)

At 6 minutes (100%):

⏰ Reminder 3 - 100% TAT Threshold [BREACHED] [TEST MODE]

Allocated: 6h  | Elapsed: 6.0h
Remaining: 0.0h | Due by: Today 2:06 PM (OVERDUE)

Note: Test mode active (1 hour = 1 minute)

📊 KPI Queries Using Alert Data

Average Response Time After Each Alert Type:

SELECT 
  alert_type,
  ROUND(AVG(tat_hours_elapsed), 2) as avg_elapsed,
  ROUND(AVG(tat_hours_remaining), 2) as avg_remaining,
  COUNT(*) as alert_count,
  COUNT(CASE WHEN was_completed_on_time = true THEN 1 END) as completed_on_time
FROM tat_alerts
GROUP BY alert_type
ORDER BY threshold_percentage;

Approvers Who Frequently Breach:

SELECT 
  u.display_name,
  u.department,
  COUNT(CASE WHEN ta.is_breached = true THEN 1 END) as breach_count,
  AVG(ta.tat_hours_elapsed) as avg_time_taken,
  COUNT(DISTINCT ta.level_id) as total_approvals
FROM tat_alerts ta
JOIN users u ON ta.approver_id = u.user_id
WHERE ta.is_breached = true
GROUP BY u.user_id, u.display_name, u.department
ORDER BY breach_count DESC
LIMIT 10;

Time-to-Action After Alert:

SELECT 
  alert_type,
  threshold_percentage,
  ROUND(AVG(
    EXTRACT(EPOCH FROM (completion_time - alert_sent_at)) / 3600
  ), 2) as avg_hours_to_respond_after_alert
FROM tat_alerts
WHERE completion_time IS NOT NULL
GROUP BY alert_type, threshold_percentage
ORDER BY threshold_percentage;

🔄 Alert Lifecycle

1. Alert Created (When Threshold Reached)

{
  alertType: 'TAT_50',
  thresholdPercentage: 50,
  tatHoursAllocated: 12,
  tatHoursElapsed: 6.0,
  tatHoursRemaining: 6.0,
  alertSentAt: '2024-10-06T14:30:00Z',
  expectedCompletionTime: '2024-10-06T18:00:00Z',
  isBreached: false,
  wasCompletedOnTime: null, // Not completed yet
  metadata: { testMode: true, ... }
}

2. Approver Takes Action

// Updated when level is approved/rejected
{
  ...existingFields,
  wasCompletedOnTime: true,  // or false
  completionTime: '2024-10-06T16:00:00Z'
}

3. Displayed in UI

// Shows all historical alerts for that level
// Color-coded by threshold
// Shows completion status if completed

🎓 Understanding the Data

Allocated Hours (tat_hours_allocated)

Total TAT time given to approver for this level

Example: 12 hours
Meaning: Approver has 12 hours to approve/reject

Elapsed Hours (tat_hours_elapsed)

Time used when the alert was sent

Example: 6.0 hours (at 50% alert)
Meaning: 6 hours have passed since level started

Remaining Hours (tat_hours_remaining)

Time left when the alert was sent

Example: 6.0 hours (at 50% alert)
Meaning: 6 hours remaining before TAT breach
Note: Turns red if < 2 hours

Expected Completion Time

When the level should be completed

Example: Oct 6 at 6:00 PM
Meaning: Deadline for this approval level

🎯 Quick Switch Between Modes

Development (Fast Testing):

# .env
TAT_TEST_MODE=true

Restart backend → Alerts fire in minutes

Staging (Semi-Real):

# .env
TAT_TEST_MODE=false
# But use shorter TATs (2-4 hours instead of 48 hours)

Restart backend → Alerts fire in hours

Production (Real):

# .env
TAT_TEST_MODE=false
# Use actual TATs (24-48 hours)

Restart backend → Alerts fire in days
