An organization should manage its suppliers and external resources by evaluating and documenting relevant suppliers, as required by ISO 9001:2015. This involves establishing criteria to assess suppliers, such as price, quality, and delivery time. The organization should also consider a risk-based approach to prioritize audits and assessments, focusing more on suppliers that pose higher risks to operations. Certified suppliers, like those with ISO 9001:2015 certification, may require less direct auditing due to their regular audits by accredited bodies. Additionally, organizations should ensure that necessary resources are determined and provided for the effective implementation and continual improvement of the Quality Management System (QMS).
