What action should be taken if a supplier does not provide proof of QA program execution?

When a supplier does not provide proof of Quality Assurance (QA) program execution, retaining documentation for purchaser audits is essential. This action is crucial because it ensures that there is a record of the supplier's compliance status, which can be reviewed during audits, providing accountability and transparency in the supply chain process.

Retaining documentation serves multiple purposes. It helps in assessing the supplier’s ongoing performance and quality control measures, which is vital for maintaining product integrity and safety. Moreover, this documentation can support future decision-making regarding supplier reliability and can be beneficial if there are disputes or quality issues down the line, enabling the purchaser to demonstrate due diligence.

Having this documentation allows an organization to maintain a robust quality management system by keeping track of suppliers' outputs and adherence to quality standards even if immediate corrective actions, such as seeking a new supplier, are not taken. This approach also helps in building a relationship with the supplier, allowing for improvement opportunities rather than immediately escalating the situation.
