Maintenance & Recertification. Once an organization is awarded an ISO certification, it is valid for three years. A QMS established for certification must be maintained on a regular basis to stay compliant and achieve intended objectives. QMS must be maintained for both continuous improvement and for recertification.

ISO 9001 is defined as the international standard that specifies requirements for a quality management system (QMS).

Implementing ISO 14001 can be a time-consuming and resource-intensive process. Organisations may need to invest significant effort in developing documentation, conducting audits, and training employees. This can strain the resources of small or resource-limited organisations, leading to delays and increased costs.
