Git Strategy Maestro

# Git Strategy Implementation Plan: E-commerce Platform ## Executive Summary Based on the analysis of your large-scale e-commerce platform's requirements, we recommend implementing a modified trunk-based development approach with short-lived feature branches. This strategy will support your microservices architecture, accommodate the needs of your six squads, and maintain SOC 2 compliance while optimizing for daily deployments. ## Branching Strategy ### Model Selection & Rationale We recommend adopting a trunk-based development model with the following modifications to support your scale: - Main branch (`main`) serves as the single source of truth - Short-lived feature branches (lifetime < 24 hours) - Protected release branches for each environment - Hotfix branches with expedited review process ### Branch Types & Purposes 1. Main Branch (`main`) - Source of truth for all deployments - Always deployable to production - Protected from direct commits 2. Feature Branches (`feature/squad-name/JIRA-ID-description`) - Created for each development task - Merged within 24 hours - Automatically deleted after merge 3. Environment Branches - `release/dev` - `release/staging` - `release/pre-prod` - `release/prod` ### Protection Rules - All merges require approved pull requests - Status checks must pass before merge - Linear history enforced through rebase - Branch protection patterns: ``` main release/* ``` ## Workflow Configuration ### Code Review Process 1. Automated code owners assignment based on squad ownership 2. Minimum two approvals required for merge 3. Squad lead approval mandatory for cross-squad changes 4. Automated assignment of reviewers based on code expertise ### Automation Rules 1. Pre-commit Hooks - Lint checking - Secret detection - Conventional commit message enforcement 2. CI Pipeline Optimization - Parallel test execution - Incremental builds - Caching of dependencies - Squad-specific test segregation ### Quality Gates 1. Automated Checks - Unit test coverage (minimum 80%) - Integration test suite - Security scanning - SOC 2 compliance validation 2. Manual Checks - Product owner sign-off for feature completion - Security review for sensitive changes - Architecture review for cross-service changes ## Security Implementation ### Access Control Matrix - Squad Members - Read/write access to their service repositories - Read access to dependent services - Squad Leads - Admin access to squad repositories - Write access to dependent services - Platform Team - Admin access across all repositories - External Collaborators - Read-only access with explicit approval ### Compliance Measures 1. Audit Trail Requirements - Signed commits mandatory - Detailed merge commit messages - Automated changelog generation - Retention of all CI/CD logs 2. SOC 2 Controls - Automated security scanning - Regular access review - Change management documentation - Incident response procedures ## Performance Optimization ### Repository Structure 1. Monorepo Strategy per Squad - Separate repositories for each squad's services - Shared libraries in dedicated repositories - Automated dependency management 2. Large File Handling - Git LFS for binary assets - Exclude build artifacts - Regular repository cleanup ### CI/CD Optimization 1. Jenkins Pipeline Improvements - Parallel execution across squads - Incremental testing - Caching strategies - Resource allocation per squad ## Training & Documentation ### Priority Training Areas 1. Advanced Git Operations - Conflict resolution workshops - Rebase vs. merge strategies - Git hooks development - Troubleshooting sessions 2. Squad Lead Training - Code review best practices - Branch management - Security protocols - Compliance requirements ### Documentation Requirements 1. Technical Guides - Git workflow procedures - CI/CD pipeline documentation - Security protocols - Troubleshooting guides 2. Process Documentation - Code review guidelines - Release procedures - Emergency protocols - Cross-squad collaboration ## Implementation Timeline ### Phase 1: Foundation (Weeks 1-2) - Set up branch protection rules - Configure CI/CD pipelines - Implement basic automation ### Phase 2: Security & Compliance (Weeks 3-4) - Deploy access control matrix - Implement audit trails - Configure compliance checks ### Phase 3: Training & Rollout (Weeks 5-6) - Conduct training sessions - Begin phased implementation - Monitor and adjust ### Phase 4: Optimization (Weeks 7-8) - Fine-tune CI/CD performance - Optimize repository structure - Implement advanced automation ## Risk Mitigation ### Identified Risks 1. Initial Productivity Impact - Mitigation: Phased rollout and comprehensive training 2. CI/CD Pipeline Performance - Mitigation: Incremental optimization and parallel execution 3. Cross-squad Coordination - Mitigation: Clear documentation and communication channels 4. Compliance Adherence - Mitigation: Automated compliance checks and regular audits ## Success Metrics ### Primary Metrics 1. Development Velocity - Time to merge (target: <4 hours) - Pipeline execution time (target: <20 minutes) - Deployment frequency (target: 5+ per day) 2. Code Quality - Reduction in merge conflicts (target: 50%) - Test coverage (target: >80%) - Successful deployment rate (target: >99%) ### Monitoring Plan - Weekly metrics review - Monthly strategy adjustment - Quarterly compliance audit - Continuous feedback collection This strategy provides a robust foundation for scaling your development operations while maintaining security and compliance requirements. Regular reviews and adjustments will ensure continued effectiveness as your team grows and evolves.
