Design Prototyping Workflow Guide

Status: Complete Implementation Guide
Version: 1.0
Purpose: Step-by-step procedures for creating interactive prototypes that validate design decisions
Applicable To: Any product design and development process

Overview

This guide provides comprehensive procedures for creating interactive prototypes that bring static designs to life, validate user interactions, and test critical user journeys. The approach emphasizes strategic prototyping that focuses on high-risk, high-value interactions while maintaining development efficiency.

Key Benefits

  • Risk Reduction: Validate design decisions before development
  • User Validation: Test interactions with real users early
  • Team Alignment: Shared understanding of complex interactions
  • Development Speed: Clear interaction specifications reduce back-and-forth

Prototype Planning and Scope

Step 1: Strategic Prototype Planning

Define what needs to be prototyped and at what fidelity level:

// prototype-planning.ts - Prototype planning framework
interface PrototypeSpec {
  feature: string;
  risk: 'low' | 'medium' | 'high';
  impact: 'low' | 'medium' | 'high';
  fidelity: 'low' | 'mid' | 'high' | 'coded';
  priority: number;
  estimatedTime: string;
  successCriteria: string[];
}

const prototypePlan: PrototypeSpec[] = [
  {
    feature: 'User Onboarding',
    risk: 'high',
    impact: 'high',
    fidelity: 'high',
    priority: 1,
    estimatedTime: '3-5 days',
    successCriteria: [
      '80% completion rate in user testing',
      'Time to first value < 5 minutes',
      'Clear understanding of value proposition'
    ]
  },
  {
    feature: 'Email Editor',
    risk: 'high',
    impact: 'high', 
    fidelity: 'high',
    priority: 2,
    estimatedTime: '5-7 days',
    successCriteria: [
      'Drag-and-drop functionality intuitive',
      'Mobile editing possible',
      'Email creation < 3 minutes'
    ]
  },
  {
    feature: 'Settings Pages',
    risk: 'low',
    impact: 'medium',
    fidelity: 'mid',
    priority: 5,
    estimatedTime: '1-2 days',
    successCriteria: [
      'Standard patterns followed',
      'All settings discoverable'
    ]
  }
];

Step 2: Fidelity Decision Matrix

Choose appropriate fidelity based on risk and complexity:

Risk/Complexity Low Impact Medium Impact High Impact
Low Risk Skip Low Fidelity Mid Fidelity
Medium Risk Low Fidelity Mid Fidelity High Fidelity
High Risk Mid Fidelity High Fidelity Coded Prototype

Step 3: Prototype Scope Definition

# Prototype Scope Document Template

## Feature: [Feature Name]
### Core User Journey
- **Entry Point**: How users arrive at this feature
- **Primary Path**: The happy path through the interaction
- **Alternative Paths**: Edge cases and error states
- **Exit Points**: How users leave or complete the flow

### Key Interactions to Test
1. **[Interaction Name]**
   - **Trigger**: What initiates this interaction
   - **Feedback**: What response the user sees/feels
   - **Success State**: What indicates completion
   - **Error Handling**: How failures are communicated

### Success Metrics
- **Task Completion Rate**: [Target %]
- **Time on Task**: [Target time]
- **Error Rate**: [Target %]
- **User Satisfaction**: [Target score]

### Testing Scenarios
1. **New User**: First-time experience
2. **Return User**: Familiar with basic flows
3. **Power User**: Advanced feature usage
4. **Error Recovery**: How users handle mistakes

Prototype Creation Tools and Techniques

Step 1: Tool Selection Matrix

Choose the right tool based on fidelity and team needs:

Tool Fidelity Learning Curve Collaboration Best For
Figma Mid-High Medium Excellent Design teams, handoff
Framer High High Good Complex interactions
Principle High High Limited Motion design
InVision Low-Mid Low Excellent Clickable wireframes
Coded Highest Highest Good Technical validation

Step 2: Figma Prototyping Setup

// figma-prototype-setup.js - Figma prototyping best practices
const FigmaPrototypeConfig = {
  // Frame setup
  frameSettings: {
    device: 'Desktop',
    width: 1440,
    height: 1024,
    // Use consistent frame sizes across prototype
  },
  
  // Interaction settings
  interactions: {
    defaultTransition: {
      type: 'smart_animate',
      duration: 300,
      easing: 'ease_in_out'
    },
    hoverStates: {
      duration: 150,
      easing: 'ease_out'
    },
    pageTransitions: {
      duration: 400,
      easing: 'ease_in_out'
    }
  },
  
  // Component states
  componentStates: {
    buttons: ['default', 'hover', 'active', 'disabled', 'loading'],
    inputs: ['default', 'focus', 'error', 'success'],
    cards: ['default', 'hover', 'selected']
  },
  
  // Overlay settings
  overlays: {
    modals: {
      background: 'rgba(0, 0, 0, 0.5)',
      closeOnClickOutside: true,
      position: 'center'
    },
    tooltips: {
      position: 'auto',
      trigger: 'hover'
    }
  }
};

Step 3: Interactive Component Creation

// interactive-components.ts - Component interaction patterns
export const InteractionPatterns = {
  // Button interactions
  button: {
    states: ['idle', 'hover', 'active', 'disabled', 'loading'],
    transitions: {
      'idle->hover': { duration: 150, easing: 'ease-out' },
      'hover->active': { duration: 100, easing: 'ease-in' },
      'active->idle': { duration: 200, easing: 'ease-out' }
    },
    feedback: {
      hover: { transform: 'translateY(-2px)', shadow: 'elevated' },
      active: { transform: 'translateY(0px)', shadow: 'pressed' },
      loading: { cursor: 'not-allowed', opacity: 0.7 }
    }
  },
  
  // Form field interactions
  formField: {
    states: ['empty', 'focus', 'filled', 'error', 'disabled'],
    transitions: {
      'empty->focus': { 
        labelFloat: true, 
        borderColor: 'primary',
        duration: 200 
      },
      'focus->filled': { 
        validation: 'real-time',
        duration: 100 
      },
      'filled->error': { 
        shake: true,
        borderColor: 'error',
        duration: 300 
      }
    }
  },
  
  // Modal interactions
  modal: {
    entrance: {
      backdrop: { opacity: '0->0.5', duration: 200 },
      content: { 
        opacity: '0->1',
        scale: '0.9->1',
        translateY: '20px->0',
        duration: 300,
        delay: 100
      }
    },
    exit: {
      content: { 
        opacity: '1->0',
        scale: '1->0.9',
        duration: 200
      },
      backdrop: { 
        opacity: '0.5->0', 
        duration: 200,
        delay: 100
      }
    }
  }
};

  transform: translateY(-50%) scale(0.85);
  background: white;
  padding: 0 4px;
}

/* Modal animations */
.modal {

    opacity: 1;
    transform: translateY(0) scale(1);
  }
}

@keyframes spin {
  to { transform: rotate(360deg); }
}

    this.flowStates = new Map();
  }
  
  // Email editor drag-and-drop flow
  setupEmailEditorFlow() {
    const flow = {

        frequency,
        severity: issueSeverity.get(issue) || 0,
        priority: frequency * (issueSeverity.get(issue) || 0)
      }))
      .sort((a, b) => b.priority - a.priority);
  }
}
