Mobile Code Impact Assessment

Mobile Code Impact Assessment

Overview

Core principle: Systematically evaluate code changes for potential impact on mobile platform functionality, ensuring offline capabilities, API compatibility, and cross-platform consistency remain intact.

Critical assessment: Mobile platform operates offline-first with local storage, synchronization, digital signatures, and field operations - changes must preserve these capabilities.

When to Use This Skill

Trigger Conditions:

• Before deploying any backend API changes
• When modifying data structures or schemas
• Before implementing authentication changes
• When updating database schemas or migrations
• Before modifying file upload/download functionality
• When changing offline synchronization logic
• Before implementing new features that affect mobile users
• When troubleshooting mobile app issues after backend changes

Mandatory Application:

• Required for all backend code changes
• Must be completed before mobile app releases
• Required for database schema changes
• Must be verified before production deployments
• Required for API contract modifications

Step-by-Step Procedure

Step 1: Change Analysis and Categorization

Analyze the proposed code changes and categorize their potential mobile impact:

// Change impact analysis framework
const changeImpactAnalysis = {
  changeCategories: {
    api_contract_changes: {
      risk_level: 'HIGH',
      mobile_impact: ['API calls', 'Data synchronization', 'Offline functionality'],
      assessment_required: ['API compatibility', 'Response format validation', 'Error handling']
    },
    
    data_schema_changes: {
      risk_level: 'CRITICAL',
      mobile_impact: ['Local storage', 'Data synchronization', 'Offline operations'],
      assessment_required: ['Schema migration', 'Data integrity', 'Sync conflicts']
    },
    
    authentication_changes: {
      risk_level: 'HIGH',
      mobile_impact: ['User sessions', 'API access', 'Offline authentication'],
      assessment_required: ['Token handling', 'Session management', 'Security compliance']
    },
    
    file_handling_changes: {
      risk_level: 'MEDIUM',
      mobile_impact: ['Document uploads', 'Offline file storage', 'Media handling'],
      assessment_required: ['File format support', 'Storage limitations', 'Sync performance']
    },
    
    business_logic_changes: {
      risk_level: 'MEDIUM',
      mobile_impact: ['Workflow execution', 'Validation rules', 'Business rules'],
      assessment_required: ['Logic consistency', 'Rule enforcement', 'Error scenarios']
    }
  },

  changeScopeAnalysis: {
    database_changes: ['Schema migrations', 'Data seeding', 'Query optimizations'],
    api_changes: ['Endpoint modifications', 'Request/response formats', 'Authentication'],
    frontend_changes: ['UI components', 'State management', 'User interactions'],
    infrastructure_changes: ['Server configuration', 'Caching layers', 'CDN updates']
  },

  impactSeverityLevels: {
    CRITICAL: 'Breaks core mobile functionality - blocks deployment',
    HIGH: 'Affects key mobile features - requires immediate attention',
    MEDIUM: 'Minor impact on mobile experience - plan for future release',
    LOW: 'Negligible impact - monitor in production'
  }
};

// Analyze specific changes
function analyzeCodeChanges(changes) {
  const impactAssessment = {
    categories: [],
    severity: 'LOW',
    affected_mobile_features: [],
    required_testing: [],
    mitigation_strategies: []
  };

  for (const change of changes) {
    const category = categorizeChange(change);
    const impact = assessMobileImpact(change, category);
    
    impactAssessment.categories.push(category);
    impactAssessment.affected_mobile_features.push(...impact.features);
    impactAssessment.required_testing.push(...impact.testing);
    
    if (getSeverityLevel(impact.risk) > getSeverityLevel(impactAssessment.severity)) {
      impactAssessment.severity = impact.risk;
    }
  }

  impactAssessment.mitigation_strategies = generateMitigationStrategies(impactAssessment);
  
  return impactAssessment;
}

Change Categorization:

• API contract modifications
• Data schema changes
• Authentication system updates
• File handling modifications
• Business logic updates
• Infrastructure changes

Step 2: Mobile Platform Feature Mapping

Map backend changes to specific mobile platform capabilities:

// Mobile platform feature mapping
const mobilePlatformFeatures = {
  offline_storage: {
    dependencies: ['database_schema', 'api_endpoints', 'file_handling'],
    critical_components: ['SQLite_ENCRYPTED', 'FILESYSTEM_ENCRYPTED', 'COMPRESSED_ARCHIVE'],
    failure_impacts: ['Data loss', 'Sync failures', 'Offline inoperability']
  },

  synchronization_engine: {
    dependencies: ['api_endpoints', 'conflict_resolution', 'queue_management'],
    critical_components: ['HYBRID_SYNC_ENGINE', 'CONFLICT_RESOLUTION', 'DELTA_COMPRESSION'],
    failure_impacts: ['Data inconsistency', 'Sync conflicts', 'Performance degradation']
  },

  digital_signatures: {
    dependencies: ['crypto_services', 'certificate_management', 'timestamp_authority'],
    critical_components: ['ECDSA_SIGNATURES', 'CERTIFICATE_VALIDATION', 'OFFLINE_SIGNING'],
    failure_impacts: ['Legal document invalidity', 'Compliance violations', 'Business process blocks']
  },

  field_operations: {
    dependencies: ['location_services', 'sensor_integration', 'workflow_engine'],
    critical_components: ['GPS_TRACKING', 'SENSOR_DATA_CAPTURE', 'OFFLINE_WORKFLOWS'],
    failure_impacts: ['Field work interruption', 'Safety compliance issues', 'Productivity loss']
  },

  multi_modal_capture: {
    dependencies: ['file_upload', 'media_processing', 'storage_quota'],
    critical_components: ['PHOTO_CAPTURE', 'VIDEO_RECORDING', 'AUDIO_TRANSCRIPTION'],
    failure_impacts: ['Evidence collection failure', 'Quality inspection blocks', 'Documentation gaps']
  },

  user_authentication: {
    dependencies: ['auth_endpoints', 'token_management', 'biometric_support'],
    critical_components: ['JWT_TOKENS', 'BIOMETRIC_UNLOCK', 'OFFLINE_AUTH'],
    failure_impacts: ['App inaccessibility', 'Security breaches', 'User experience degradation']
  }
};

// Map changes to affected features
function mapChangesToFeatures(changes, featureMap) {
  const affectedFeatures = new Map();
  
  for (const change of changes) {
    for (const [feature, config] of Object.entries(featureMap)) {
      if (config.dependencies.some(dep => change.type.includes(dep))) {
        if (!affectedFeatures.has(feature)) {
          affectedFeatures.set(feature, {
            feature: feature,
            changes: [],
            risk_level: 'LOW',
            impact_description: ''
          });
        }
        
        const featureInfo = affectedFeatures.get(feature);
        featureInfo.changes.push(change);
        
        // Assess risk level
        if (config.critical_components.some(comp => change.affects.includes(comp))) {
          featureInfo.risk_level = 'CRITICAL';
        } else if (change.type.includes('breaking')) {
          featureInfo.risk_level = 'HIGH';
        }
        
        // Generate impact description
        featureInfo.impact_description = generateImpactDescription(feature, change, config);
      }
    }
  }
  
  return Array.from(affectedFeatures.values());
}

Feature Mapping:

• Offline storage capabilities
• Synchronization engine
• Digital signatures
• Field operations workflows
• Multi-modal data capture
• User authentication

Step 3: API Compatibility Assessment

Evaluate API changes for mobile app compatibility:

// API compatibility assessment
const apiCompatibilityAssessment = {
  endpoint_changes: {
    breaking_changes: ['URL changes', 'Method changes', 'Required parameter additions'],
    compatible_changes: ['Optional parameter additions', 'Response field additions', 'Documentation updates'],
    versioning_strategy: ['Semantic versioning', 'Deprecation headers', 'Migration guides']
  },

  request_format_changes: {
    breaking: ['Content type changes', 'Required field additions', 'Field type changes'],
    compatible: ['Optional field additions', 'Field format flexibility', 'Backward compatibility']
  },

  response_format_changes: {
    breaking: ['Field removal', 'Structure changes', 'Error format changes'],
    compatible: ['Field additions', 'Optional field changes', 'Metadata additions']
  },

  authentication_changes: {
    breaking: ['Token format changes', 'Endpoint protection changes', 'Permission model changes'],
    compatible: ['Additional auth methods', 'Token refresh improvements', 'Security enhancements']
  }
};

// Assess API compatibility
function assessApiCompatibility(apiChanges, mobileRequirements) {
  const compatibilityReport = {
    breaking_changes: [],
    compatible_changes: [],
    migration_required: false,
    mobile_app_update_needed: false,
    backward_compatibility_maintained: true
  };

  for (const change of apiChanges) {
    if (isBreakingChange(change, mobileRequirements)) {
      compatibilityReport.breaking_changes.push({
        change: change,
        impact: assessBreakingImpact(change),
        mitigation: suggestBreakingMitigation(change)
      });
      compatibilityReport.migration_required = true;
      compatibilityReport.mobile_app_update_needed = true;
      compatibilityReport.backward_compatibility_maintained = false;
    } else {
      compatibilityReport.compatible_changes.push({
        change: change,
        impact: assessCompatibleImpact(change),
        benefits: identifyCompatibilityBenefits(change)
      });
    }
  }

  return compatibilityReport;
}

// Check if change breaks mobile compatibility
function isBreakingChange(change, mobileRequirements) {
  // Check against mobile platform requirements
  if (change.type === 'endpoint_removal' && mobileRequirements.critical_endpoints.includes(change.endpoint)) {
    return true;
  }
  
  if (change.type === 'response_format_change' && change.breaks_existing_parsing) {
    return true;
  }
  
  if (change.type === 'authentication_change' && change.requires_app_update) {
    return true;
  }
  
  return false;
}

API Assessment:

• Endpoint compatibility
• Request/response format changes
• Authentication modifications
• Breaking vs compatible changes
• Migration requirements

Step 4: Data Structure Impact Analysis

Evaluate database and data structure changes for mobile implications:

// Data structure impact analysis
const dataStructureImpact = {
  schema_changes: {
    table_additions: { impact: 'LOW', mobile_handling: 'Automatic sync' },
    table_removals: { impact: 'CRITICAL', mobile_handling: 'Migration required' },
    column_additions: { impact: 'LOW', mobile_handling: 'Backward compatible' },
    column_removals: { impact: 'HIGH', mobile_handling: 'Data migration needed' },
    column_type_changes: { impact: 'CRITICAL', mobile_handling: 'Schema migration' },
    index_changes: { impact: 'MEDIUM', mobile_handling: 'Performance impact' }
  },

  data_migration_requirements: {
    offline_data_preservation: 'Maintain data during migration',
    conflict_resolution: 'Handle concurrent mobile changes',
    rollback_capability: 'Ability to revert failed migrations',
    testing_validation: 'Verify mobile app compatibility'
  },

  synchronization_implications: {
    data_sync_performance: 'Impact on sync speed and battery usage',
    conflict_resolution_complexity: 'Increased conflict scenarios',
    offline_functionality: 'Potential offline capability disruption',
    data_integrity: 'Risk of data corruption or loss'
  }
};

// Analyze data structure changes
function analyzeDataStructureChanges(changes, mobileDataModel) {
  const impactReport = {
    schema_changes: [],
    migration_requirements: [],
    sync_implications: [],
    mobile_app_impacts: [],
    risk_assessment: 'LOW'
  };

  for (const change of changes) {
    const changeType = categorizeDataChange(change);
    const mobileImpact = assessMobileDataImpact(change, mobileDataModel);
    
    impactReport.schema_changes.push({
      change: change,
      type: changeType,
      mobile_impact: mobileImpact
    });
    
    // Assess migration needs
    if (mobileImpact.requires_migration) {
      impactReport.migration_requirements.push({
        change: change,
        migration_type: determineMigrationType(change),
        complexity: assessMigrationComplexity(change),
        testing_requirements: defineMigrationTesting(change)
      });
    }
    
    // Evaluate sync implications
    const syncImpact = evaluateSyncImplications(change, mobileDataModel);
    if (syncImpact.significant) {
      impactReport.sync_implications.push(syncImpact);
    }
    
    // Update risk assessment
    impactReport.risk_assessment = escalateRiskLevel(impactReport.risk_assessment, mobileImpact.risk);
  }

  return impactReport;
}

// Categorize data structure changes
function categorizeDataChange(change) {
  if (change.action === 'ADD_TABLE') return 'table_addition';
  if (change.action === 'DROP_TABLE') return 'table_removal';
  if (change.action === 'ADD_COLUMN') return 'column_addition';
  if (change.action === 'DROP_COLUMN') return 'column_removal';
  if (change.action === 'MODIFY_COLUMN') return 'column_modification';
  return 'unknown';
}

// Assess mobile-specific data impact
function assessMobileDataImpact(change, mobileDataModel) {
  const impact = {
    requires_migration: false,
    affects_offline_storage: false,
    impacts_sync_performance: false,
    breaks_existing_functionality: false,
    risk: 'LOW'
  };

  // Check if change affects mobile data model
  if (mobileDataModel.tables.includes(change.table)) {
    impact.affects_offline_storage = true;
    
    if (['DROP_TABLE', 'DROP_COLUMN', 'MODIFY_COLUMN'].includes(change.action)) {
      impact.requires_migration = true;
      impact.breaks_existing_functionality = true;
      impact.risk = 'CRITICAL';
    }
  }

  return impact;
}

Data Structure Analysis:

• Schema change categorization
• Migration requirement assessment
• Synchronization implications
• Mobile app data model impacts

Step 5: Offline Capability Assessment

Evaluate changes for impact on offline mobile functionality:

// Offline capability assessment
const offlineCapabilityAssessment = {
  storage_impact: {
    local_database_changes: 'SQLite schema modifications',
    file_storage_changes: 'Offline file handling updates',
    cache_invalidation: 'Offline cache management',
    storage_quota_changes: 'Device storage limitations'
  },

  synchronization_impact: {
    api_endpoint_changes: 'Sync endpoint modifications',
    data_format_changes: 'Sync payload structure changes',
    conflict_resolution_updates: 'Conflict handling improvements',
    network_optimization_changes: 'Bandwidth and performance optimizations'
  },

  functionality_impact: {
    offline_workflow_changes: 'Field operation process updates',
    signature_capability_changes: 'Digital signature functionality',
    data_capture_changes: 'Multi-modal data collection',
    validation_rule_changes: 'Offline business rule enforcement'
  }
};

// Assess offline capability impact
function assessOfflineCapabilityImpact(changes, offlineCapabilities) {
  const offlineImpactReport = {
    storage_impacts: [],
    sync_impacts: [],
    functionality_impacts: [],
    offline_compatibility: 'COMPATIBLE',
    required_updates: [],
    risk_assessment: 'LOW'
  };

  for (const change of changes) {
    // Assess storage impact
    const storageImpact = evaluateStorageImpact(change, offlineCapabilities.storage);
    if (storageImpact.significant) {
      offlineImpactReport.storage_impacts.push(storageImpact);
    }

    // Assess sync impact
    const syncImpact = evaluateSyncImpact(change, offlineCapabilities.sync);
    if (syncImpact.significant) {
      offlineImpactReport.sync_impacts.push(syncImpact);
    }

    // Assess functionality impact
    const functionalityImpact = evaluateFunctionalityImpact(change, offlineCapabilities.functions);
    if (functionalityImpact.significant) {
      offlineImpactReport.functionality_impacts.push(functionalityImpact);
    }
  }

  // Determine overall compatibility
  offlineImpactReport.offline_compatibility = determineOfflineCompatibility(offlineImpactReport);
  offlineImpactReport.required_updates = generateRequiredUpdates(offlineImpactReport);
  offlineImpactReport.risk_assessment = calculateOfflineRisk(offlineImpactReport);

  return offlineImpactReport;
}

// Evaluate storage impact
function evaluateStorageImpact(change, storageCapabilities) {
  const impact = {
    significant: false,
    type: 'none',
    description: '',
    mitigation: ''
  };

  if (change.affects.includes('database_schema')) {
    impact.significant = true;
    impact.type = 'schema_change';
    impact.description = 'Database schema change requires offline storage migration';
    impact.mitigation = 'Implement schema migration with backward compatibility';
  }

  if (change.affects.includes('file_handling')) {
    impact.significant = true;
    impact.type = 'file_handling';
    impact.description = 'File handling change affects offline document storage';
    impact.mitigation = 'Update offline file storage mechanisms';
  }

  return impact;
}

// Determine offline compatibility
function determineOfflineCompatibility(impactReport) {
  const hasBreakingChanges = [
    ...impactReport.storage_impacts,
    ...impactReport.sync_impacts,
    ...impactReport.functionality_impacts
  ].some(impact => impact.type.includes('breaking'));

  if (hasBreakingChanges) {
    return 'BREAKING_CHANGES';
  }

  const hasSignificantImpacts = [
    ...impactReport.storage_impacts,
    ...impactReport.sync_impacts,
    ...impactReport.functionality_impacts
  ].some(impact => impact.significant);

  if (hasSignificantImpacts) {
    return 'REQUIRES_UPDATES';
  }

  return 'COMPATIBLE';
}

Offline Assessment:

• Storage capability impacts
• Synchronization changes
• Offline functionality effects
• Compatibility determination

Step 6: Cross-Platform Compatibility Verification

    api_support: 'iOS-specific API requirements',
    storage_limitations: 'iOS storage constraints',
    background_processing: 'iOS background execution limits',

      compatibilityReport.flutter_compatibility = 'ISSUES_FOUND';
      compatibilityReport.platform_specific_issues.push(...flutterIssues.map(issue => ({ platform: 'Flutter', ...issue })));
    }
  }

  // Identify universal fixes
  compatibilityReport.universal_fixes = identifyUniversalFixes(compatibilityReport.platform_specific_issues);

  // Determine deployment blockers
  compatibilityReport.deployment_blockers = identifyDeploymentBlockers(compatibilityReport);

  return compatibilityReport;
}

// Check platform-specific compatibility
function checkPlatformCompatibility(change, platformReqs) {
  const issues = [];

  // Check API compatibility
  if (change.type === 'api_change' && platformReqs.api_support) {
    if (!platformReqs.api_support.includes(change.api_version)) {
      issues.push({
        type: 'api_incompatibility',
        description: `${change.description} not supported on this platform`,
        severity: 'HIGH',
        fix: `Implement platform-specific API handling`
      });
    }
  }

    if (change.storage_requirement > platformReqs.storage_limitations.max) {
      issues.push({
        type: 'storage_limitation',
        description: `Storage requirement exceeds platform limit`,
        severity: 'MEDIUM',
        fix: `Implement storage optimization or chunking`
      });
    }
  }

  return issues;
}

  }

  // Data structure risks
  if (impactAnalysis.data_impact.migration_requirements.length > 0) {
    riskFactors.push({
      type: 'data_migration_required',
      severity: 'CRITICAL',
      description: 'Data structure changes require mobile migration',
      impact: 'Offline data integrity at risk'
    });
  }

  // Offline capability risks

    });
  }

  return riskFactors;
}

// Generate mitigation strategies
function generateMitigationStrategies(riskFactors) {
  const strategies = [];

          timeline: '2-3 sprints'
        });
        break;

      case 'platform_compatibility_issues':
        strategies.push({
          strategy: 'platform_specific_implementations',
          description: 'Implement platform-specific handling for compatibility issues',
          effort: 'MEDIUM',

}

Risk Assessment:

• Overall risk level calculation
• Specific risk factor identification
• Mitigation strategy generation
• Testing requirement definition
• Deployment recommendation creation

Step 8: Impact Report Generation and Recommendations

Create comprehensive impact report with actionable recommendations:

// Generate comprehensive impact report
function generateComprehensiveImpactReport(allAssessments) {
  const impactReport = {
    executive_summary: generateExecutiveSummary(allAssessments),
    detailed_findings: {
      change_analysis: allAssessments.changeAnalysis,
      feature_mapping: allAssessments.featureMapping,
      api_compatibility: allAssessments.apiCompatibility,
      data_impact: allAssessments.dataImpact,
      offline_assessment: allAssessments.offlineAssessment,
      cross_platform: allAssessments.crossPlatform
    },
    risk_assessment: allAssessments.riskAssessment,
    recommendations: {
      immediate_actions: [],
      short_term_mitigation: [],
      long_term_improvements: [],
      testing_requirements: [],
      deployment_strategy: null
    },
    approval_requirements: determineApprovalRequirements(allAssessments),
    timeline_estimates: estimateImplementationTimeline(allAssessments)
  };

  // Generate recommendations
  impactReport.recommendations = generateActionableRecommendations(allAssessments);

  return impactReport;
}

// Generate executive summary
function generateExecutiveSummary(assessments) {
  const summary = {
    overall_risk: assessments.riskAssessment.overall_risk_level,
    critical_findings: [],
    recommended_actions: [],
    deployment_readiness: 'UNKNOWN'
  };

  // Identify critical findings
  if (assessments.apiCompatibility.breaking_changes.length > 0) {
    summary.critical_findings.push('Breaking API changes detected');
  }

  if (assessments.offlineAssessment.offline_compatibility === 'BREAKING_CHANGES') {
    summary.critical_findings.push('Offline functionality breaking changes');
  }

  if (assessments.crossPlatform.deployment_blockers.length > 0) {
    summary.critical_findings.push('Cross-platform deployment blockers identified');
  }

  // Determine deployment readiness
  if (summary.overall_risk === 'CRITICAL') {
    summary.deployment_readiness = 'BLOCKED';
    summary.recommended_actions.push('Address critical issues before deployment');
  } else if (summary.overall_risk === 'HIGH') {
    summary.deployment_readiness = 'REQUIRES_APPROVAL';
    summary.recommended_actions.push('Obtain stakeholder approval for high-risk changes');
  } else {
    summary.deployment_readiness = 'READY';
    summary.recommended_actions.push('Proceed with standard deployment process');
  }

  return summary;
}

// Generate actionable recommendations
function generateActionableRecommendations(assessments) {
  const recommendations = {
    immediate_actions: [],
    short_term_mitigation: [],
    long_term_improvements: [],
    testing_requirements: [],
    deployment_strategy: null
  };

  // Immediate actions for critical issues
  if (assessments.riskAssessment.overall_risk_level === 'CRITICAL') {
    recommendations.immediate_actions.push(
      'STOP deployment and address critical mobile compatibility issues',
      'Schedule emergency review with mobile development team',
      'Implement temporary workarounds for blocking issues'
    );
  }

  // Short-term mitigation
  recommendations.short_term_mitigation = assessments.riskAssessment.mitigation_strategies
    .filter(strategy => strategy.effort !== 'HIGH')
    .map(strategy => strategy.description);

  // Long-term improvements
  recommendations.long_term_improvements = [
    'Implement automated mobile impact assessment in CI/CD pipeline',
    'Create mobile compatibility testing framework',
    'Establish mobile change approval process',
    'Develop mobile impact assessment training program'
  ];

  // Testing requirements
  recommendations.testing_requirements = assessments.riskAssessment.testing_requirements;

  // Deployment strategy
  recommendations.deployment_strategy = determineDeploymentStrategy(assessments);

  return recommendations;
}

// Determine deployment strategy
function determineDeploymentStrategy(assessments) {
  const risk = assessments.riskAssessment.overall_risk_level;

  switch (risk) {
    case 'CRITICAL':
      return {
        strategy: 'BLOCKED',
        reason: 'Critical mobile compatibility issues prevent deployment',
        next_steps: 'Address critical issues and re-assess'
      };

    case 'HIGH':
      return {
        strategy: 'PHASED_ROLLOUT',
        reason: 'High-risk changes require controlled deployment',
        next_steps: 'Deploy to limited user group first, monitor closely'
      };

    case 'MEDIUM':
      return {
        strategy: 'STANDARD_DEPLOYMENT',
        reason: 'Medium-risk changes can follow standard process',
        next_steps: 'Include mobile testing in deployment verification'
      };

    default:
      return {
        strategy: 'FAST_TRACK',
        reason: 'Low-risk changes can be deployed normally',
        next_steps: 'Standard deployment process with mobile monitoring'
      };
  }
}

Impact Report Generation:

• Executive summary creation
• Detailed findings compilation
• Risk assessment integration
• Actionable recommendations
• Approval requirement determination
• Timeline estimation

Success Criteria

• Code changes analyzed for mobile platform impact
• Mobile platform features mapped to backend changes
• API compatibility assessed for breaking changes
• Data structure changes evaluated for mobile implications
• Offline capabilities assessed for disruption risks
• Cross-platform compatibility verified
• Risk assessment completed with mitigation strategies
• Comprehensive impact report generated with recommendations
• Deployment strategy determined based on risk level

Common Pitfalls

1. Underestimating Offline Impact - Mobile platform is offline-first, changes must preserve offline capabilities
2. API Breaking Changes - Mobile apps depend on stable API contracts
3. Data Schema Changes - Mobile local storage must remain compatible
4. Authentication Changes - Mobile offline authentication must be maintained
5. Cross-Platform Inconsistencies - Changes must work across iOS, Android, and web
6. Insufficient Testing - Mobile impact requires thorough testing before deployment
7. Missing Stakeholder Communication - Mobile team must be involved in backend changes
