SOLID Code Collaboration Guidelines

Single Responsibility Principle (SRP) in Team Context

graph TD
    A[Feature Request] --> B{Single Purpose?}
    B -->|No| C[Break Down Feature]
    B -->|Yes| D[Assign to Developer]
    C --> E[Multiple Classes/Components]
    E --> F[Multiple Developers]
    D --> G[Single Developer]
    F --> H[Coordinate Integration]
    G --> I[Independent Development]
    H --> J[Integration Review]
    I --> J
    J --> K[Quality Review]

Team Practice: - Break large features into single-responsibility components - Assign components to different developers based on expertise - Ensure each developer focuses on one clear responsibility - Coordinate integration points between team members

Open/Closed Principle (OCP) in Collaboration

graph LR
    A[Base Implementation] --> B[Extension Points Defined]
    B --> C[Team A: Core Feature]
    B --> D[Team B: Extensions]
    C --> E[Stable Base Code]
    D --> F[Plugin Architecture]
    E --> G[No Modifications]
    F --> G
    G --> H[Collaborative Integration]

Team Practice: - Design extension points before implementation - Frontend and backend teams work on stable interfaces - New features extend existing code without modification - Clear contracts prevent breaking changes

Dependency Inversion Principle (DIP) in Team Structure

graph TB
    subgraph "High-Level Modules"
        A[Business Logic Team]
        B[API Layer Team]
    end

    subgraph "Abstractions"
        C[Interfaces/Contracts]
        D[Data Transfer Objects]
    end

    subgraph "Low-Level Modules"
        E[Database Team]
        F[External Service Team]
        G[Infrastructure Team]
    end

    A --> C
    B --> C
    C --> D
    D --> E
    D --> F
    D --> G

Team Practice: - Define interfaces collaboratively before implementation - High-level teams (business logic) don't depend on implementation details - Low-level teams (database, infrastructure) implement defined contracts - Changes in implementation don't affect business logic teams

Code Review Process for SOLID Quality

Review Assignment Matrix

graph TD
    A[Pull Request Created] --> B{Change Type}

    B -->|Frontend Only| C[Frontend Lead + 1 Peer]
    B -->|Backend Only| D[Backend Lead + 1 Peer]
    B -->|Full-Stack| E[Both Leads + 2 Peers]
    B -->|Architecture Change| F[Both Leads + CPTO]
    B -->|Security Related| G[Security Review Required]

    C --> H[SOLID Principles Check]
    D --> H
    E --> H
    F --> H
    G --> H

    H --> I{SOLID Compliant?}
    I -->|No| J[Architecture Discussion]
    I -->|Yes| K[Approve for Merge]

    J --> L[Refactor Required]
    L --> A

SOLID-Focused Review Checklist

Single Responsibility Review

• [ ] Does each class/function have one clear purpose?
• [ ] Can the change reason be described in one sentence?
• [ ] Are there mixed concerns that should be separated?

Open/Closed Review

• [ ] Can new behavior be added without modifying existing code?
• [ ] Are there proper extension points?
• [ ] Does the change break existing functionality?

Liskov Substitution Review

• [ ] Are inheritance relationships correct?
• [ ] Can subclasses be used wherever parent classes are expected?
• [ ] Do overridden methods maintain the parent contract?

Interface Segregation Review

• [ ] Are interfaces focused and cohesive?
• [ ] Are there unused methods being forced on implementations?
• [ ] Should large interfaces be split?

Dependency Inversion Review

• [ ] Are high-level modules independent of low-level details?
• [ ] Are dependencies properly injected?
• [ ] Are there direct dependencies on concrete implementations?
