- Verification & Validation
- Definitions
- Validation: checking the data entered is reasonable
- Verification: checking the final data entry matches the data captured
- Types of Error
- Invalid data - the data is either impossible or unreasonable
- Inaccurate data - valid data that is incorrect
- Validation Checks
- Spreadsheet
- Database
- Potential Issues
- Validation
- Error trapping is only as good as the software design to track the errors
- Validation only makes sure the data is reasonable, not that is correct
- Verification
- Both double-entry and proof reading are time consuming and expensive
- Verification only makes sure that the data entered matches that in the input form, not that it is correct
- Human error is still possible
