# ggen Marketplace Maturity Matrix

## Overview

The **Marketplace Maturity Matrix** is a comprehensive scoring system for evaluating the quality and readiness of packages in the ggen marketplace. It provides transparency to users about package stability, maintenance status, and adoption maturity.

**Total Score**: 0-100 points across 6 dimensions
**Maturity Levels**: Experimental → Beta → Production → Enterprise

---

## Best Practices

### For Package Authors

1. **Documentation First**: Complete README, examples, and changelog before release
2. **Test Coverage**: Aim for 80%+ coverage before going to production
3. **Security**: Run `cargo audit` and fix vulnerabilities before release
4. **Performance**: Include benchmarks and verify determinism
5. **Maintenance**: Commit to regular releases (monthly/quarterly)

### For Package Consumers

1. **Start with Production**: Only use Experimental packages for R&D
2. **Monitor Maturity**: Re-evaluate package maturity quarterly
3. **Report Issues**: Help package authors improve through feedback
4. **Test Beta Packages**: Provide feedback before packages go Production

### For Marketplace Managers

1. **Incentivize Production**: Feature production packages prominently
2. **Support Growth**: Help Beta packages reach Production
3. **Monitor Trends**: Track average maturity score over time
4. **Community Health**: Celebrate packages reaching Enterprise level

---

## FAQ

**Q: Why is my package stuck in Beta?**
A: Check the feedback section. Most packages need improved test coverage and documentation to reach Production.

**Q: How often should I re-evaluate maturity?**
A: Quarterly or after significant releases. Update automatically in CI/CD pipeline.

**Q: What's the difference between Production and Enterprise?**
A: Production (61-80) is stable and suitable for most uses. Enterprise (81-100) has exceptional maturity, high adoption, and dedicated maintenance.

**Q: How is adoption scored?**
A: Downloads, academic citations, and active contributors. Real-world usage data drives this score.

**Q: Can I improve maturity score quickly?**
A: Yes, focus on high-impact areas: test coverage (testing), security scanning (security), and release cadence (maintenance) often provide quick wins.
