Deficiency Severity
Classify control-deficiency severity from likelihood and potential magnitude.
Description
Control-deficiency screening combines likelihood and potential magnitude.
Control-deficiency screening combines likelihood and potential magnitude. The category formula is a simplified heuristic.1
Classify control-deficiency severity from likelihood and potential magnitude.
When to use Deficiency Severity
Use this tool to classify control-deficiency severity from likelihood and potential magnitude.
Prepare the documented facts, aligned totals or expected/observed evidence labels requested. Choose applicable requirements and thresholds separately before interpreting a planning screen.
How to use Deficiency Severity and understand its results
- Prepare the documented facts, aligned totals or expected/observed evidence labels requested. Choose applicable requirements and thresholds separately before interpreting a planning screen.
- Enter likelihoodPercent, maximumPotentialMisstatement, materiality, controlFailureSystemic using the field table and calculation rules, then run the tool.
- Read expectedMisstatement, materialityRatio, severity. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| likelihoodPercent | Misstatement likelihood (%) | number; minimum: 0; maximum: 100 | Required |
| maximumPotentialMisstatement | Maximum potential misstatement | number; minimum: 0 | Required |
| materiality | Materiality | number; minimum: 0 | Required |
| controlFailureSystemic | Control failure is systemic | boolean | Required |
Enter likelihood 0–100, nonnegative maximum, positive materiality and systemic flag. Systemic with ratio≥1 gives material-weakness; else ratio≥.5 OR likelihood≥50 gives significant-deficiency; else deficiency.
expected=maximum×likelihood%/100; ratio=maximum/materiality Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| expectedMisstatement | Probability-weighted misstatement | number; minimum: 0 |
| materialityRatio | Potential misstatement to materiality | number; minimum: 0 |
| severity | Deficiency severity | string; one of "deficiency", "significant-deficiency", "material-weakness" |

"input": {
"likelihoodPercent": 60,
"maximumPotentialMisstatement": 600,
"materiality": 1000,
"controlFailureSystemic": false
},
"output": {
"expectedMisstatement": 360,

} Limitations and assumptions
The expected amount does not drive classification. No governing definition or formal deficiency assessment is established.
Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
