| == Software Safety Criticality Matrix: |
| |
| |
| |
| |=== |
| | |Severity Category (I-IV) | | | |
| |Software Control Category |Catastrophic (I) |Critical (II) |Marginal (III) |Negligible(IV) |
| |1 |SwCI 1 |SwCI 1 |SwCI 3 |SwCI 4 |
| |2 |SwCI 1 |SwCI 2 |SwCI 3 |SwCI 4 |
| |3 |SwCI 2 |SwCI 3 |SwCI 4 |SwCI 4 |
| |4 |SwCI 3 |SwCI 4 |SwCI 4 |SwCI 4 |
| |5(NSI) |SwCI 5 |SwCI 5 |SwCI 5 |SwCI 5 |

| == Table for unhandled inputs: |
| |
| If one opens a requirement artifact with the artifact explorer, and it has 0 Software Control Category attributes and 1 Software Severity attribute, I assume it has no SwCI computed attribute. |
| |
| To cover cases like above, here is a table: |
| |
| |=== |
| |Software Control Category |Safety Severity |Calculated SwCI |
| |Does not exist | Does not exist |Does not exist |
| |Exists |Doesn’t |Doesn’t |
| |Doesn’t |Exists |Doesn’t |
| |Exists |Exists |Exists (as calculated) |
| |Unspecified |Has value |Unspecified |
| |Has Value |Unspecified |Unspecified |
