Not the right question to ask. There is such a thing as EPM - enterprise project management system (more detailed description here
). Which consists of three integral components:
1. The methodology of project management (schedule, document templates, methods of planning, risk management, etc.), which describes the project management processes.
2. The PMIS is the information system project management - actually the task of which is to automate the processes described in the methodology and to consolidate information on projects of the company.
3. Project office - a structural unit, which is responsible for the implementation and development of the methodology and PMIS, training, and internal consulting.
I.e. the rules of use of the system (as I understand means the PMIS), no. It's just a guide to work in the PMIS should be.
With regard to methodology, this link is a detailed example of writing methodology (download) mahamba.com/ru/reglament-upravleniya-proektami
