Which PM system does your organization use?
If you don't know whether your organization has adopted a PM system or which system it uses, how do you find out? The quickest way is to ask your manager. In addition, many organizations publish articles about their PM system in company newsletters and refer to it in their annual reports and other publications. In some organizations, an internal performance measurement team provides training on the system to existing employees and new hires.
Look to all these sources for information if necessary. And listen for mention of a particular PM system while attending CEO speeches and all-staff meetings.
