| Key Concept | Details |
|---|---|
| Core Assumption | Product quality is influenced by the quality of the processes applied. |
| Type of Improvement | Model-Based Test Process Improvement uses structured models for enhancement based on best practices. |
| Popular Models | - TMMi® (Test Maturity Model Integration)- TPI NEXT® |
| Project-Level Application | Focuses on project-specific test activities (e.g., test planning), may omit organizational-level (e.g., test policy). |
| TMMi® | - 5 Maturity Levels- Practices, sub-practices, examples- Complements CMMI®, now used independently- Agile guidelines available |
| TPI NEXT® | - 16 Key Test Areas (e.g., test strategy, metrics, tools)- Each has 4 maturity levels- Uses maturity matrix and checkpoints |
