How does software testing contribute to the quality of delivered software? [K2]
A . By detecting and removing all the defects in the delivered code and ensuring that all tests adhere to the quality standards set for the project
B . By measuring reliability of the software and ensuring that it is always above 99.99%
C . By identifying root causes of defects from past projects and using the lessons learned to improve processes and thus help to reduce the defect count
D . By detecting all deviations from coding good practice and ensuring that these are corrected

Answer: C

Explanation:

Software testing contributes to the quality of delivered software by identifying root causes of defects from past projects and using the lessons learned to improve processes and thus help to reduce the defect count. Software testing is a process of verifying and validating that a software product meets the specified requirements and expectations of the stakeholders1. Software testing can detect defects in the software product and provide information about its quality1. Software testing can also identify root causes of defects from past projects and use the lessons learned to improve processes and thus help to reduce the defect count1. This can be done by using techniques such as root cause analysis, defect prevention, causal analysis, process improvement, etc1. These techniques can help to identify and eliminate the sources of defects in the software development lifecycle and prevent them from recurring in future projects1. Therefore, software testing contributes to the quality of delivered software by identifying root causes of defects from past projects and using the lessons learned to improve processes and thus help to reduce the defect count.
