In another thread, Qualmx posted: What I have implemented is the next: I do monthly audits (5 processes each month) and opportunities of improvements, when detected are included in the audit report. Is known that for OFI, Actions are not required, but.... Is common that even if any OFI it may have benefits to the process, the auditee doesn´t do anything. Quarterly the QMS responsible gathers the audit reports, organizes a meeting, invites the auditees and discuss about the OFI´s and if qms coordinator/auditees agree, implement the necessary OFI´s. My two cents My interest is understanding and discussing the information/data on which to base the selection of the specific process and quantity of processes etc to be audited in any period of time. Why 5 Process each month? What is the rationale? Why once a year, as others do? As we know, ISO 9001:2015 requires an audit program to be established and audits to be planned etc. including "frequency". Nowhere does it state that a calendar of (say) monthly audits is necessary.
