There’s probably better phrasing than ‘DMARC compliant’ here, but here’s my stab at describing the processes. note, this is very close to the language I use with clients.

p=none: mail sent by authorized users of this domain may or may not be aligned in a DMARC compliant way.

p=quarantine: mail sent by authorized users of this domain should be aligned in a DMARC compliant way. Mail that is unaligned may or may not be legitimate messages from this organization.

p=reject: all mail sent from this domain should be aligned in a DMARC compliant way. Mail that is unaligned is not authorized by the domain owner and may be discarded or rejected by the recipient.
