Screen Flow Definition

Position in workflow: v0.4 User Journey Mapping → v0.4 Screen Flow Definition → v0.5 Red Team Review

Screens are where journeys become tangible. This skill transforms user journeys into a screen inventory with navigation paths and feature mappings.

Consumes

This skill requires prior work from v0.3-v0.4:

  • UJ-* user journey entries (from v0.4 User Journey Mapping) — Journey steps become screens; each step asks "What screen enables this action?"
  • FEA-* feature entries (from v0.3 Features Value Planning) — Features map to screens showing which features appear on which screens
  • PER-* persona entries (from v0.4 Persona Definition) — Persona context (technical level, role) shapes screen design choices and complexity
  • MVP-SCOPE artifact (from v0.3 Features Value Planning) — Explicit feature boundary; screens must render only MVP-scoped features, backlog features deferred
  • BR-* business rules (from v0.3 Commercial Model) — Constraints affecting screen layout (pricing tier rules affect which settings appear, role-based visibility, data refresh rates, etc.)

This skill assumes v0.4 User Journey Mapping is complete.

Produces

This skill creates/updates:

  • SCR-* entries (screens, confidence 2-3/5) — Screen inventory with journey/feature/persona mappings showing purpose, actions, navigation, and constraints
  • DES-* entries (design system components, confidence 2-3/5) — Reusable UI elements and patterns identified across screens
  • Feature-to-Screen matrix — Validation artifact showing every FEA- and every UJ- step mapped to SCR-
  • Screen count and complexity assessment — Critical for v0.5 technical stack selection (number of screens informs frontend framework needs)

All SCR- entries should include:

  • confidence: 2-3/5 (based on journey validation and feature implementation status)
  • Evidence source citations (UJ-ID, FEA-ID, PER-ID references)
  • Forward target: "Would move to 4/5 if validated in wireframe review or prototype testing"

Example SCR- entry with confidence:

SCR-001: Main Dashboard
Type: Page
Purpose: Central hub showing key metrics and quick actions
Journeys: UJ-001 (Step 4), UJ-002 (Step 5), UJ-003 (Step 1)
Features: FEA-007 (dashboard), FEA-003 (reports preview), FEA-012 (notifications) — all in MVP-SCOPE
Confidence: 2/5 (source: journey-mapping + design-validation; not yet wireframed)

Primary Actions: Create Report, View Data Sources, Access Settings
Secondary Actions: Invite Team, View Help

Navigation:
  From: SCR-000 (Login), any screen via nav bar
  To: SCR-002 (Report Builder), SCR-003 (Data Sources), SCR-010 (Settings)

Content:
  - Key metrics summary (3-5 cards) → DES-001 (Data Card)
  - Recent reports list → DES-002 (Report List)
  - Data source health status → DES-003 (Status Badge)
  - Notification bell → FEA-012

Constraints: BR-015 (data refresh rate), BR-020 (role-based visibility)
Design Notes: PER-001 needs "busy dashboard" - show progress at a glance without overwhelming

Next Target: "Would move to 4/5 if wireframe validated with 3+ target personas"

Example DES- entry with confidence:

DES-001: Data Card
Type: Component
Used In: SCR-001 (Dashboard), SCR-005 (Analytics)
Purpose: Display single metric with trend indicator
Confidence: 2/5 (source: design-pattern-research; component not yet coded)

States:
  - Default: Shows value + trend arrow
  - Loading: Skeleton placeholder
  - Empty: "No data yet" message
  - Error: "Failed to load" with retry

Variants: Small (dashboard, 120px width), Large (detail view, 240px width)
Accessibility: ARIA labels for trend direction, keyboard navigation support

Next Target: "Would move to 4/5 if implemented and tested across both use cases"

Screen Types

TypeDefinitionDesign PriorityExample
PageFull viewport, primary navigation targetHighDashboard, Settings
ModalOverlay, blocks underlying pageMediumConfirmation, Quick Edit
PanelSlide-out, contextual detailMediumDetail View, Filters
ComponentReusable UI elementVariesHeader, Data Table

Rule: Start with Pages, then identify where Modals/Panels reduce navigation friction.

Navigation Patterns

Choose a pattern based on product type:

PatternWhen to UseExample Products
Hub & SpokeDashboard-centric appsAnalytics, CRM
Linear FlowWizard/checkout processesOnboarding, E-commerce
HierarchicalContent-heavy appsDocumentation, CMS
FlatSimple single-purpose appsTimer, Calculator

Most SaaS products use Hub & Spoke with occasional Linear Flows for onboarding/purchase.

Mapping Process

  1. Pull UJ- (journeys) and FEA- (features) from prior steps

    • Journeys define the paths; features define the capabilities

  2. Inventory unique screens needed across all journeys

    • Walk through each journey step and ask: "What screen does this happen on?"

  3. Map features to screens (many:many relationship)

    • One feature may appear on multiple screens
    • One screen may contain multiple features

  4. Define navigation structure

    • How do users get from screen to screen?
    • What's the hierarchy? What's always accessible?

  5. Identify shared components

    • Headers, footers, navigation bars
    • Common patterns: data tables, forms, cards

  6. Create SCR- entries with journey and feature traceability

  7. Create DES- entries for design system elements

SCR- Output Template

Screen Categories

Organize screens by function:

CategoryExamplesDesign Priority
Entry PointsLogin, Landing, SignupHigh (first impressions)
Core WorkflowMain task screensHigh (value delivery)
Settings/AdminPreferences, Account, BillingMedium (necessary)
Support/HelpDocs, Contact, FAQLow (failure recovery)

Rule: Invest design effort proportional to priority. Don't over-design settings screens.

Feature-to-Screen Matrix

Create a mapping matrix:

FEA-001 (auto-sync)✓
FEA-003 (reports)PreviewFull
FEA-007 (dashboard)✓
FEA-010 (auth)✓

This reveals:

  • Features spread across multiple screens (normal)
  • Features on no screens (problem: orphaned)
  • Screens with no features (problem: unnecessary)

Anti-Patterns to Avoid

Anti-PatternSignalFix
Screen explosion>20 unique screens for MVPConsolidate; use modals/panels instead
Feature-per-screen1:1 FEA to SCR mappingGroup related features on screens
No shared componentsEvery screen is uniqueExtract DES- patterns
Navigation dead-endsCan't get back from a screenEnsure bidirectional paths
Journey disconnectSCR- not tied to UJ-Every screen serves a journey
Modal abuseEverything is a modalModals for confirmations/quick edits only

Quality Gates

Before proceeding to v0.5 Red Team Review:

  • All UJ- steps mapped to screens
  • All FEA- features appear on at least one screen
  • Navigation paths are bidirectional (no dead-ends)
  • Shared components identified as DES- entries
  • Screen count reasonable for MVP (<15 pages)
  • Entry points and core workflow prioritized

Downstream Connections

SCR- and DES- entries feed into:

ConsumerWhat It UsesExample
v0.5 Technical Stack SelectionScreen complexity informs frontend needs"20 screens → need component library"
v0.6 Technical SpecificationScreens inform API data needsSCR-001 → API-001 (dashboard data)
v0.7 Build ExecutionScreens become implementation tasksEPIC-03 builds SCR-001–005
DesignSCR- entries become wireframes/mockupsSCR-001 → Figma design
