The Responsible Business Alliance (RBA) is a nonprofit organization that works with companies in the electronics, retail, and other industries to promote sustainable and ethical practices in their global supply chains. One of the key initiatives of the RBA is the Validated Assessment Process (VAP), which is a comprehensive audit program designed to evaluate and improve the social and environmental performance of suppliers in these industries.

The RBA's VAP audit process includes a series of assessments, such as the RBA Self-Assessment Questionnaire (SAQ), the RBA-Validated Audit Process (VAP), and the RBA-Online Audit Report System (OARS). These assessments help to evaluate suppliers' performance in a range of areas, including labor practices, health and safety, environmental management, and business ethics.
