Each supplier will have to be audited more or less frequently, depending on its performance; these audits will generate audit reports. Depending on the results of the audit, an action plan will be set up by the supplier to meet our requirements, always with the objective of delegating, as much as possible, the investigation phases to suppliers to save the company’s internal resources. To do this, we can integrate a supplier portal into the software suite used by the supplier quality manager. This portal is secure and allows to control all exchanges with suppliers. We will intervene in the preparation of the audit and especially in the follow-up of action plans, allowing interaction with the supplier through a workflow that the supplier quality assurance and the supplier will come to update together. It is also possible to exchange and store documents in order to centralize all the information transmitted by the supplier. In addition, the portal is equipped with a discussion thread to trace the exchanges on a file.
