Our PMs talk to customers all the time. We want to use Aha for basic CRM such that anytime one of us talks to an organization, we capture an indexed, searchable note for that customer detailing who, what, when, and topics. Maybe we're interviewing about a specific new enhancement, so we could tag these notes against relevant epics, features, etc. Later, when viewing a given (say) epic, we could see all the org/customer notes that were associated with it. This isn't extending existing Notes, more about orienting notes directly to Organizations.
We've built something approximating this using custom tables within Organizations, but it's clunky. We can tag epics, features, and such within a given customer note, but when you view the (say) epic, it doesn't show up as a related item.
I have a call with Customer X, so I open Aha to that Organization.
I can look through previous notes that other PMs have had with Customer X, including details of who they met with and what they said.
I talk to the customer and capture notes on the conversation in a unique note. I tag this note to Feature A and Feature B since they have interesting feedback on that.
Later I open Feature A and see this as one of several customer notes PMs have taken that are relevant.
