The sustainability of quality Management System implementation in DARRO I is a primal concern now since the office is certified as ISO 9001:2015 compliant. The importance of documented information is considered. An assessment workshop was conducted in February 4, 2020 at the DARRO I Conference Room for the Document Controllers with the RCAO Nestor T. Pagaduan. The group shared about the good and bad points of document control work from the start of QMS implementation in June 24, 2019 to the present. The tool of root cause analysis was used to determine the causes of the concerns of the group. The On-line Document Tracking System (ODTS) implementation concerns were also discussed. It takes commitment to do ones job well amidst the limited resources, the differences and varying concerns of the office.
