Given that background research on article creation is not limited to data analysis or testing for features developed within Growth it’s important that this reaches the latter type of audience and I believe a little bit of redundancy doesn’t hurt.
Yeah I don't mind redundancy on principle, however, I do want us to be very careful about viewing R&D as separate from our actual team work. For instance, we might learn things about article creation in general that are of broad interest, but we did it in order to provide a solid background for product changes by Growth. The primary purpose of the analysis is informing change, with educating the community or organization at large a tertiary goal.
If there is analysis work, such as traffic analysis, that doesn't fit within a single team's scope but impacts the entire organization... well obviously that makes sense to put in an overall Analytics report. But just like the UX team does not have a separate report, but instead reports what it does through and for our cross-functional teams, I feel very strongly that reporting about analysis work should be done through normal team reporting whenever possible. This keeps our analysis conceptually tied to measuring outcomes and trends relevant to product work, rather than just generalized R&D.
