How does ServiceNow SPM determine required resources for a project or project task?

[RamchandarK]

Hello ServiceNow Community,

I am working with ServiceNow Strategic Portfolio Management (SPM), specifically Project Portfolio Management (PPM) and Resource Management, and I have a question regarding resource determination.

My questions are:

1. Does ServiceNow SPM provide any built‑in feature to decide how many resources (members) are required for a particular project or project task?
2. If yes, how is the required resource count determined in ServiceNow?
   • Is it based on planned effort, task duration, or capacity planning?
3. Who is expected to decide the required resources in ServiceNow standard practice?
   • Project Manager
   • Resource Manager
   • System‑calculated logic
4. At which stage of the lifecycle is this typically done?
   • Idea
   • Demand
   • Project Planning
5. How do Resource Plans / Resource Assignments contribute to deciding the number of required resources?
6. Is there any automatic calculation in ServiceNow (OOTB) that converts effort into resource count, or is it always manually estimated and then capacity‑validated?
7. Can this be done at the Project Task level, or only at the Project level?
