Severity | Interpretation |
|---|---|
Critical | A problem that renders the system unusable because either an entire function is unusable and no workaround exists, or because the use of the current system compromises data integrity or results in data loss. Catastrophic problems also include significant and non-obvious quantitative errors, as well as all human and instrument safety issues. |
High | A serious issue that does not affect data integrity (meaning data loss, corruption of data, or the wrong answer), but affects the user's ability to use the product as designed. It can be a failure, design issue, or documentation error or omission. A workaround may or may not exist. |
Medium | A minor error or poor behavior of a product feature. There is probably a workaround. |
Low | An issue that has a limited effect on the usage of the product; a defect with such low visibility that a user might never see it; or ease-of-use issues or other items that do not cause any performance degradation. |
Risk | Interpretation |
|---|---|
High | Occurrence is likely to happen and can compromise operation. |
Medium | Occurrence is uncommon, but if it occurs, it can compromise operation. |
Low | Issue is minor; however, the software might operate differently from a user’s expectations. A workaround is often available. |
No Risk | Issue causes no problems but is commonly an inconsistency or a 4- Low issue. |
