Functional Correctness measures how accurately a system provides results. It is part of the ISO 25010 quality model.
Key Aspects:
1. Accuracy of results
2. Precision of calculations
3. Consistency of outputs
4. Adherence to specifications
5. Reliability of functions
Evaluating Functional Correctness:
1. Defining expected results
2. Conducting thorough testing
3. Comparing actual vs. expected outputs
4. Analysing error rates
5. Verifying data integrity
High functional correctness ensures users can trust system outputs.
