## Strategy

### Current Focus (Updated 2026-01-28)

1. **User Authentication** (Priority: High)
   - Status: Fact-finding complete, positive validation
   - Outcome: 82% of users want accounts feature
   - Next: Move to planning phase
   - Impact: Projected 15-20% reduction in booking abandonment

2. **Guide Offline Mode** (Priority: Medium)
   - Status: New opportunity from user research
   - Validation: 45% of users request offline access
   - Next: Create card, begin fact-finding

3. **Performance Optimization** (Priority: High)
   - Status: Completed (BRIK-ENG-0005)
   - Outcome: Page load improved 200ms (from 1.2s to 1.0s)
   - Impact: Bounce rate reduced by 8%

## Risks

### Active Risks

- **GDPR Compliance** (Severity: High, Added: 2026-01-28)
  - Source: Card BRIK-ENG-0001 blocked on legal review
  - Impact: Delays user auth feature by 1-2 weeks
  - Mitigation: Legal review in progress, backup plan if negative

- **Platform Auth Compatibility** (Severity: Medium, Added: 2026-01-28)
  - Source: Technical fact-finding on BRIK-ENG-0001
  - Impact: May require custom auth implementation
  - Mitigation: Architecture spike planned

## Opportunities

### Validated (Ready for Cards)

- **Guide Offline Mode**
  - Evidence: User research (45% request), customer-input
  - Value: Reduce support load, enable international travelers
  - Effort: Medium (service worker + cache strategy)
  - Recommend: Create card, prioritize for Q2

### Under Investigation

- **Mobile App Push Notifications**
  - Source: Scan detected user feedback themes
  - Status: Need fact-finding to validate demand
  - Next: Survey users, check technical feasibility

## Learnings

### 2026-01-28: User Authentication Feature

- **What worked:**
  - Early user research prevented building unwanted features
  - Platform auth reuse saved 2 weeks of development
  - Fact-finding phase caught GDPR issue before build

- **What didn't work:**
  - Initial scope too broad (social login + email)
  - Legal review not started early enough
  - Performance testing delayed fact-finding exit

- **Process improvements:**
  - Start legal review during fact-finding, not planning
  - Scope to MVP first, add features incrementally
  - Performance baselines at start of fact-finding

- **Technical insights:**
  - Platform auth works with Brikette (confirmed via spike)
  - Social login adds 40% complexity vs email-only
  - Auth overhead: <50ms on booking flow

## Metrics

### Booking Flow (Updated 2026-01-28)

- **Completion Rate:** 68% → 72% (+4pp)
  - Source: Performance optimization (BRIK-ENG-0005)
  - Measurement: Google Analytics, 30-day rolling average
  - Target: 75% by end of Q1

- **Page Load Time:** 1.2s → 1.0s (-200ms)
  - Source: Performance optimization (BRIK-ENG-0005)
  - Measurement: Real User Monitoring (RUM)
  - Target: <900ms by end of Q2

- **Support Tickets:** Baseline established (52/month)
  - Next: Track impact of offline mode and user auth
  - Target: Reduce by 20% (10 tickets/month) with self-service
