Who is the SR for matrixed personnel supporting another organization (i.e. Program Executive Offices (PEOs))?

The Parent organization will complete the SRPE on their matrixed acquisition employees. However, the Matrix organization supervisor can provide recommended SPRE comments to the SR of the Parent organization. The IDP Supervisor (Parent organization) will initiate the SRPE request to their Rater (Parent organization) to complete the SRPE. There will have to be some coordination amongst the supervisors from the Parent and Matrix organization.
