Maturity Assessment

DevOps Maturity Levels:

Basic:

• Manual deployments
• No CI/CD detected
• Minimal automation

Intermediate:

• CI/CD pipeline detected
• Containerization (Docker)
• Basic monitoring

Advanced:

• Full CI/CD with multiple stages
• Container orchestration (K8s)
• Infrastructure as Code
• Comprehensive monitoring

Cloud-Native:

• GitOps practices (ArgoCD)
• Service mesh
• Observability stack
• Multi-cloud or hybrid

Error Handling

• Private repositories: Note as limitation

• Incomplete config analysis: Provide partial results

• Job posting only signals: Lower confidence
