## Summary
|
|
|
|
A framework for evaluating an organization's progress in adopting DevOps practices, typically ranging from ad-hoc processes to highly optimized and automated environments. The model defines **five maturity stages**:
|
|
|
|
| Stage | Name | Key Characteristics |
|
|
|-------|------|---------------------|
|
|
| Phase 1 | Initial/Ad-Hoc | Siloed teams, waterfall approach, manual infrastructure, reactive monitoring, security only at release |
|
|
| Phase 2 | DevOps in Pockets | Small cross-functional teams, Agile introduction, version control, superficial automation, unit/integration testing |
|
|
| Phase 3 | Automated and Defined | Standardized processes, most infrastructure automated, security integrated into development process |
|
|
| Phase 4 | Highly Optimized | CI pipeline, immutable infrastructure, MVP and tech debt management, continuous security monitoring |
|
|
| Phase 5 | Fully Mature | Self-sufficient full-stack teams, multiple daily deployments, zero human intervention in pipeline |
|
|
|
|
## Key Focus Areas
|
|
|
|
1. **Culture and Strategy** — Teamwork, transparency, customer-centric mindset
|
|
2. **Automation** — AutoDevOps for continuous delivery and deployment
|
|
3. **Structure and Process** — Standardized, small-batch, transparent processes
|
|
4. **Collaboration and Sharing** — Cohesive teams leveraging diverse skill sets
|
|
5. **Technology** — Tool selection aligned with team needs
|
|
|
|
## Quality Criteria
|
|
|
|
- Assessment criteria (standards for evaluating maturity)
|
|
- Five maturity levels
|
|
- Core DevOps practices (release management, CI/CD, IaC, security)
|
|
- Relevant metrics (deployment frequency, MTTR, change failure rate)
|
|
- Cultural guides
|
|
- Tools and technologies
|
|
- Roles and responsibilities
|
|
|
|
## Business Benefits
|
|
|
|
- Quicker adjustment to market changes
|
|
- Capability to seize new opportunities
|
|
- Better scalability via IaC
|
|
- Enhanced operational performance
|
|
- Faster delivery times
|
|
- Improved quality via continuous monitoring and feedback
|
|
|
|
## Security Integration (DevSecOps)
|
|
|
|
The model emphasizes merging development, operations, and security into a unified process. Security progression: ad-hoc compliance scans → separate security team → security in design/architecture discussions → security updates in product workflow → preventing non-compliant code from production.
