IT Best Practices - Industry Standards & Methodologies

💻 Software Development Best Practices

Foundational

Version Control Excellence

Master distributed version control systems and collaborative development workflows.

Gitflow Workflow Implementation

# Initialize repository with Gitflow
git flow init -d

# Start a feature branch
git flow feature start authentication

# Develop and commit changes
git add .
git commit -m "Implement user authentication system"

# Publish feature branch for collaboration
git flow feature publish authentication

# Create pull request and finish feature
git flow feature finish authentication
                        

Branch Strategy Guidelines

Main/Master Branch

Production-ready code maintained through pull requests only

Develop Branch

Integration branch for ongoing development work

Feature Branches

Individual feature development with clear naming conventions

Release Branches

Preparation for production releases with final testing

Hotfix Branches

Critical production bug fixes bypassing normal flow

Intermediate

Test-Driven Development (TDD)

Write tests before code to ensure quality and prevent regressions.

Red-Green-Refactor Cycle

// 1. RED: Write failing test first
describe('User Authentication', () => {
    test('should authenticate valid user credentials', () => {
        const auth = new Authentication();
        expect(auth.login('valid@email.com', 'password123')).toBe(true);
    });
});

// 2. GREEN: Write minimal code to pass test
class Authentication {
    login(email, password) {
        // Minimal implementation
        return email.includes('@') && password.length >= 8;
    }
}

// 3. REFACTOR: Improve code while maintaining test pass
class Authentication {
    login(email, password) {
        if (!this.isValidEmail(email)) return false;
        if (!this.isStrongPassword(password)) return false;
        return this.verifyCredentials(email, password);
    }

    isValidEmail(email) {
        return /^[^\s@]+@[^\s@]+\.[^\s@]+$/.test(email);
    }

    isStrongPassword(password) {
        return password.length >= 8 && /[A-Z]/.test(password) && /[0-9]/.test(password);
    }

    verifyCredentials(email, password) {
        // Database verification logic
        return true; // Mock implementation
    }
}
                        

🔄 Code Review & Collaboration Standards

Automated Code Quality Gates

Static code analysis with ESLint/Prettier
Unit test coverage requirements (>80%)
Security vulnerability scanning with SAST
Performance benchmarking and thresholds
Automated deployment blockers for failures

Documentation Standards

README files for all projects
API documentation with OpenAPI/Swagger
Code comments for complex business logic
Architecture diagrams and system documentation
Onboarding guides for new team members

"The best practices that survive are those that address real pain points and create tangible value. Start with what's broken in your current process and work backward to the ideal solution."
