Which type of cost is related to the detection of errors?

1. Appraisal costs

2. Prevention costs

3. Failure costs

4. Operational costs

The correct answer is: Appraisal costs

Appraisal costs are directly associated with the detection of errors within a software testing context. These costs are incurred to ensure that the product meets quality standards and specifications before it is released. Appraisal activities can include testing, inspection, and reviews, all aimed at identifying defects early in the development lifecycle, thus contributing to improved product quality. The rationale behind appraisal costs being related to error detection lies in their focus on evaluating the product's quality through various testing methods and processes. By investing in appraisal activities, organizations can identify issues in the software before it reaches the end user, leading to reduced rework and enhanced customer satisfaction. In contrast, prevention costs involve the expenses related to activities designed to prevent errors from occurring in the first place, such as training, process improvement, and quality planning. Failure costs arise when errors are not detected before release, resulting in costs associated with fixing defects after deployment. Operational costs generally refer to the ongoing expenses involved in running the business or maintaining the system, which do not specifically focus on error detection.
