Description
Calculate qa process rework cost share from explicit caller-supplied inputs.
Quality records separate measured results, reference values, acceptance rules, and supporting evidence. Arithmetic consistency and record coverage can be checked against supplied criteria without establishing traceability, approving a method, or deciding product conformity.
Calculate qa process rework cost share from explicit caller-supplied inputs.
When to use this tool
Use it for qa process rework cost share when the required inputs and conventions are already available.
How to use the tool and how it works
- Enter firstPassCost, reworkCost, scrapCost, recoveredCredit, units. Use the stated units and boundary conventions.
- Run the calculation. Correct any input error before interpreting a result.
- Read netCost, reworkShare, costPerUnit. Inspect any known, defined, inclusion, or boundary flags before interpreting numeric values.
Require positive integer units, nonnegative first-pass, rework, and scrap costs with a positive gross sum, and nonnegative recoveredCredit. Return netCost after recovery, reworkShare of gross cost, and net costPerUnit.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| firstPassCost | First Pass Cost | Required. Finite number; minimum 0. |
| reworkCost | Rework Cost | Required. Finite number; minimum 0. |
| scrapCost | Scrap Cost | Required. Finite number; minimum 0. |
| recoveredCredit | Recovered Credit | Required. Finite number; minimum 0. |
| units | Units | Required. Safe integer; minimum 1. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| netCost | Net Cost | Required. Finite number. |
| reworkShare | Rework Share | Required. Finite number. |
| costPerUnit | Cost Per Unit | Required. Finite number. |

}Limitations and assumptions
- ReworkShare uses gross cost while costPerUnit uses net cost. Recovery can make net results negative; unit yield, accounting treatment, and the origin of costs are not verified.
- The field tables describe structural bounds; the mechanics also state cross-field requirements. Malformed input shapes, disallowed keys, and invalid domains cause input errors. Results must remain finite and within the declared output contract. A successful false flag or zero placeholder is distinct from an error.
- Numeric arithmetic uses binary floating point. Exact comparisons have no hidden tolerance or decimal rounding; negative zero is exported as zero. Decimal-text integer operations retain the exactness specifically stated above.
Alternative or Complementary methods
For qa process rework cost share, check the source records and the supplied rule before comparing the result with another method. Use a separate evidence or method review when arithmetic consistency alone cannot establish the required conclusion.
