# 2. Requirements

# Functional Requirements

FR1: The platform shall provide role-based authentication with distinct interfaces for organizers, speakers, partners, and attendees

FR2: Event organizers shall manage events through a 9-state workflow with parallel speaker coordination and configurable task management, including automated deadline tracking, stakeholder coordination, and real-time progress dashboards with cross-role visibility

Event Workflow (9-State State Machine): The event progresses through high-level states while speakers progress individually in parallel:

Speaker Workflow (Parallel Per-Speaker Progression): Per ADR-009, each speaker progresses independently through an 8-state machine:

• IDENTIFIED → CONTACTED → READY → INVITED → ACCEPTED → CONTENT_SUBMITTED → QUALITY_REVIEWED (terminal happy state)
• DECLINED is reachable from any non-terminal state (covers leads that don’t pan out, declined invitations, and post-acceptance withdrawals via status-history reason)
• QUALITY_REVIEWED → CONTENT_SUBMITTED is a legal back-transition (Story 11.E.8): a speaker (or organizer-on-behalf) can revise content after the moderator’s review; the new submission lands in session_content_history with a fresh version, and the derived content status returns to SUBMITTED until re-reviewed
• slot_assigned and publishable are derived flags computed at read time (no persisted columns) — slot_assigned := session.start_time IS NOT NULL, publishable := QUALITY_REVIEWED AND slot_assigned
• Speaker provisioning (User row + Cognito account + SPEAKER role grant) occurs at the CONTACTED → READY transition, gated by presence of email
• Session + PRIMARY_SPEAKER session_users row are also provisioned at CONTACTED → READY (Story 11.E.8), making the existing organizer Sessions tab and speaker portal content/material flows reachable from READY onward — not blocked behind content submission
• Capacity is enforced at READY → INVITED: organizers cannot exceed max_slots for the event
• Content versioning lives on session_content_history keyed by (session_id, submission_version) and is inserted only by ContentSubmissionService.submit() — a pure audit log of speaker submissions. The canonical current title and abstract live on sessions.title / sessions.description (Story 11.E.8 §2.9); every surface (public archive, organizer kanban, organizer session-edit modal, speaker portal form) reads from there, ensuring an edit on any surface is immediately visible to the others. speaker_pool carries only workflow state, no denormalized content fields. The legacy speaker_pool.content_status string is now derived at read time via ContentStatusDeriver (PENDING / SUBMITTED / REVISION_NEEDED / APPROVED) from the latest history row’s reviewer_feedback + workflow state — JSON shape preserved for the frontend, source of truth moved. Speaker-portal drafts live in browser localStorage; the backend /content/draft endpoint was retired

Task Management System (Configurable Work Items): Tasks are NOT workflow states - they are assignable work items with due dates triggered by workflow transitions:

Custom tasks can be created with configurable trigger states, due dates, and assigned organizers.

See Workflow State Machines for detailed implementation.

FR3: The system shall provide automated speaker invitation, submission, and material collection workflows with real-time status updates. Speaker authentication uses standard AWS Cognito with FORCE_CHANGE_PASSWORD on first login (per ADR-009 §0.5) — the invitation email carries a login link and a temporary password; no magic-link or token-based auth path exists

FR4: Partners shall access analytics dashboards showing employee attendance of their company for the past events

FR5: The platform shall support progressive event publishing with automatic content updates from topic definition through final agenda publication

FR6: Attendees shall access a prominent current event landing page featuring the upcoming BATbern event with complete logistics (date, location, free attendance), speaker lineup, agenda details, and registration functionality

FR7: The system shall integrate email notification workflows for event updates, speaker deadlines, and newsletter distribution, supported by a comprehensive email template management system that allows organizers to create, customize, and version email templates with variable substitution, multilingual support, and A/B testing capabilities for different stakeholder groups (speakers, attendees, partners, organizers)

FR8: Partner users shall vote on topic priorities and submit strategic topic suggestions outside formal partner meetings

FR10: Speaker users shall access self-service portal for submission management, agenda viewing, and presentation upload

FR11: The system shall maintain complete event archive with presentation downloads, speaker profiles, and photo galleries accessible via secondary navigation

FR12: Event organizers shall manage multi-year venue reservations, catering coordination, partner meeting scheduling, and logistics through integrated workflow tools with automated reminders and stakeholder notifications

FR13: [REMOVED - Strategic refocus per Sprint Change Proposal 2025-10-01]

FR14: Attendees shall manage personal engagement through newsletter subscriptions, content bookmarking, and presentation downloads with personalized preferences, including granular notification preference controls allowing users to opt in/out of specific notification types (event updates, speaker announcements, partner communications, system alerts) across multiple channels (email, in-app, push notifications) with frequency management and quiet hours settings

FR15: The platform shall provide mobile-optimized attendee experience with offline content access, event check-in capabilities, and progressive web app functionality

FR16: [REMOVED - Strategic refocus per Sprint Change Proposal 2025-10-01]

FR17: The system shall provide intelligent speaker matching and assignment tracking with the unified 8-state speaker workflow (IDENTIFIED → CONTACTED → READY → INVITED → ACCEPTED → CONTENT_SUBMITTED → QUALITY_REVIEWED; DECLINED reachable from any non-terminal state) per ADR-009, supporting parallel per-speaker progression, real-time organizer collaboration including slot preference collection and technical requirement tracking. Capacity is enforced by a slot-capacity gate at the READY → INVITED transition: (count(ACCEPTED) + count(INVITED)) >= max_slots blocks further invitations. There is no overflow / parking-lane state and no organizer voting mechanism — if a slot opens up (e.g., an invited speaker declines), the next speaker in READY can be invited

FR18: Event organizers shall access smart topic backlog management with visual heat map representation showing topic usage frequency over time, ML-powered similarity scoring to identify duplicate or similar topics with automated avoidance warnings, staleness detection algorithms that calculate recommended wait periods before topic reuse based on historical patterns and partner influence metrics, and intelligent duplicate avoidance that prevents organizers from selecting recently used or semantically similar topics

FR19: The platform shall implement progressive publishing engine that automatically validates content readiness (moderator quality review, abstract length limits) and publishes event information in phases (topic immediate → speakers 1 month prior → progressive agenda updates → final agenda → post-event materials) with quality control checkpoints and automated content standards enforcement

FR20: Event organizers shall receive intelligent notification system with role-based alerts, cross-stakeholder visibility, and automated escalation workflows for deadline management and task coordination, implementing multi-tier escalation rules (reminder → warning → critical → escalation to backup organizer) with configurable timing thresholds, automatic fallback notification paths, priority-based delivery guarantees, and real-time escalation status dashboards with audit trails

FR21: The system shall support long-term planning capabilities including multi-year venue booking workflows, seasonal partner meeting coordination, and strategic budget planning with automated scheduling and reminder systems

FR22: Event organizers shall manage user roles with capabilities to promote users to speaker or organizer roles, demote users with approval workflows for organizer demotions, and enforce business rules requiring minimum 2 organizers per event, maintaining complete audit trails of all role changes

FR23: Event organizers shall access a User Management interface displaying all platform users with comprehensive CRUD operations (create, read, update, delete), advanced filtering by role/company/status, search functionality with autocomplete, and the ability to view detailed user information and manage role assignments through an intuitive administrative interface, with all operations respecting business rules (minimum 2 organizers) and maintaining complete audit trails

# Non-Functional Requirements

# Sprint Planning Overview

Setup Phase: Sprint 0 (2 weeks)

• Project setup, environment configuration, team alignment
• Architecture finalization with architect
• Development environment preparation

Epic Timeline (REVISED - CRUD-First Strategy with API Consolidation):

• Epic 1: Weeks 1-9 (Foundation & Essential Infrastructure) - ✅ 100% COMPLETE
• Epic 2: Weeks 10-18 (Entity CRUD & Domain Services + API Consolidation) - ✅ 100% COMPLETE
• Epic 3: Weeks 19-21 (Historical Data Migration) - ✅ 100% COMPLETE (tooling ready)
• Epic 4: Weeks 22-26 (Public Website & Content Discovery) - ✅ 100% COMPLETE
• Epic 5: Weeks 27-35 (Enhanced Organizer Workflows) - ✅ 100% COMPLETE (including BAT-16)
• Epic 6: Weeks 36-44 (Speaker Portal & Support) - ✅ 100% COMPLETE (All stories deployed to staging, Story 6.4 QA passed)
• Epic 7: Attendee Experience — Right-Sized Contribution & Touchpoints - 📋 READY FOR STORY DETAILING (rewritten 2026-06-09; right-sized replacement for the deferred dashboards/PWA/recommendation-engine scope — five organizer-voted features composing onto existing machinery)
• Epic 8: Weeks 45+ (Partner Coordination - ✅ 100% COMPLETE 2026-02-22)
• Epic 11: Weeks 46+ (Unified Speaker Workflow Refactor - 🔨 IN PROGRESS — Phase A doc alignment landing; Phases B–F per ADR-009 and docs/plans/speaker-workflow-refactor.md. Supersedes prior Epic 9 plan.)

Reorganization Rationale: Epic structure revised to prioritize functional delivery (CRUD with consolidated APIs, data migration, public website) before workflow automation. Epic 5 completed with 9-state workflow, per-speaker coordination, task management, auto-publishing, and lifecycle automation. Epic 6 fully deployed with automated speaker invitation, self-service response portal, content submission, dashboard (WCAG 2.1 AA), and deadline reminders. Epic 8 complete with partner attendance analytics, topic voting, and meeting coordination with RFC 5545 calendar invites. Epic 7 was rewritten 2026-06-09 from its deferred over-scoped form (dashboards/PWA/recommendation engine) into a right-sized set of five organizer-voted attendee contribution & touchpoint features (see prd/epic-7-attendee-experience-enhancements.md); the prior Epic 9 (JWT magic-link speaker authentication) is superseded by Epic 11 per ADR-009, which adopts standard AWS Cognito with FORCE_CHANGE_PASSWORD first-login as the sole speaker auth path (no parallel JWT / magic-link stack).

# 4.2 Content Management & Storage Architecture

The BATbern platform manages diverse content types including company logos, speaker photos and CVs, event presentations, and historical archives. This section defines the storage architecture, CDN strategy, and content policies.

# AWS S3 Storage Strategy

Bucket Architecture:

• Environment Separation: Separate S3 buckets per environment (development, staging, production)
• Bucket Naming: batbern-{environment}-{content-type} (e.g., batbern-prod-presentations, batbern-prod-logos)
• Content Types:
  • presentations: Speaker presentation files (PDF, PPTX)
  • logos: Company and partner logos (PNG, JPG, SVG)
  • profiles: Speaker photos and CVs (JPG, PNG, PDF)
  • archives: Historical event materials and photo galleries

S3 Key Structure:

/{content-type}/{year}/{entity-id}/{filename-with-uuid}
Examples:
  /presentations/2024/evt-123/speaker-456-presentation-a7b3c9d2.pdf
  /logos/2024/company-789/logo-f3e8d1a4.png
  /profiles/2024/speaker-456/photo-b2c9e3f1.jpg

Lifecycle Policies:

• Active Content: S3 Standard storage class for content < 1 year old
• Historical Content: Transition to S3 Standard-IA after 1 year
• Archive Content: Transition to S3 Glacier after 3 years
• Retention: Indefinite retention for all event-related content

Security & Access Control:

• Private Buckets: All buckets private by default, no public access
• Presigned URLs: Time-limited presigned URLs for downloads (15-minute expiration)
• Upload Authentication: All uploads require valid JWT with appropriate role
• Server-Side Encryption: AES-256 encryption at rest (S3-SSE)
• Versioning: Enabled for accidental deletion protection

# CloudFront CDN Configuration

Distribution Strategy:

• Global CDN: CloudFront distribution per environment for fast worldwide delivery
• Origin: S3 buckets as CloudFront origins with Origin Access Identity (OAI)
• Caching: Aggressive caching for static content (TTL: 7 days)
• Custom Domain: cdn.batbern.ch, cdn-staging.batbern.ch, cdn-dev.batbern.ch

Performance Optimization:

• Edge Locations: AWS global edge network for low-latency delivery
• Compression: Automatic gzip/brotli compression for text-based files
• HTTP/2: Enabled for multiplexing and reduced latency
• Image Optimization: Lambda@Edge for automatic image resizing and format conversion

Security Headers:

• HTTPS Only: Redirect HTTP to HTTPS
• Security Headers: CORS, CSP, X-Frame-Options, X-Content-Type-Options
• Signed URLs: Optional signed URLs for sensitive content

# File Size and Format Constraints

Per Content Type:

Upload Requirements:

• Multipart Upload: Files > 10 MB use multipart upload for reliability
• Progress Tracking: Real-time upload progress for files > 1 MB
• Virus Scanning: ClamAV integration for all uploaded files
• Checksum Verification: SHA-256 checksum validation on upload completion

# Storage Quota Policies Per Role

Role-Based Quotas:

Quota Enforcement:

• Pre-Upload Check: Validate available quota before upload
• Soft Limits: Warning at 80% quota usage
• Hard Limits: Upload rejection at 100% quota
• Quota Increase: Manual approval process for speakers exceeding limits

# Backup and Disaster Recovery

Backup Strategy:

• Cross-Region Replication: Replicate production bucket to secondary region (eu-west-1 → eu-central-1)
• Versioning: S3 versioning enabled for 30-day rollback capability
• Daily Snapshots: S3 bucket inventory reports for disaster recovery planning
• Backup Testing: Quarterly restore drills to validate backup integrity

Disaster Recovery:

• RTO (Recovery Time Objective): 4 hours for full content restoration
• RPO (Recovery Point Objective): 1 hour maximum data loss
• Failover: Automatic CloudFront failover to secondary region on origin failure
• Restoration Process: Documented restoration procedures with runbooks

Data Integrity:

• Checksum Validation: SHA-256 checksums stored in database for integrity verification
• Periodic Audits: Monthly automated integrity checks comparing S3 and database records
• Orphan Detection: Identify and cleanup orphaned S3 objects without database references
