ISTQB CTAL-TM Exam - Topic 2 Question 19 Discussion

The graph indicates that a significant portion of risks, 29%, have not been mitigated, which suggests that these are either failed tests or other discovered failures. This level of unmitigated risk puts the project at risk, as it implies that there are still substantial issues that need to be addressed.

Reference: The ISTQB Advanced Level Test Manager documents outline the importance of risk-based testing and the interpretation of residual risk graphs.These graphs are used to communicate the current status of risk mitigation efforts in the project, and a high percentage of unmitigated risks is a clear indicator of potential problems1.
