This specialized area encompasses entities that provide assessment and evaluation procedures focused on the reliability, functionality, and performance of systems, components, or materials. An example would be a company contracted to rigorously check software code for bugs, vulnerabilities, and adherence to specified requirements prior to deployment.
Such providers are vital in ensuring product quality, safety, and regulatory compliance across diverse sectors. Historically, these functions were often integrated within organizations. However, outsourcing this work has become increasingly common due to its potential for cost-effectiveness, access to specialized expertise, and impartial evaluation.
