Decision for recommendation concept approach

The team did discuss the two recommendation concepts, user-based and item-based collaborative filtering, and chose an approach on the basis of several criteria. First and foremost, it was important for the team, that the recommendation concept does make use of as much gathered data as possible. Second, the recommendation concept should be as accurate as possible and third, it has to be understood by the team.

Considering the mentioned criteria, the decision was made to use user-based collaborative filtering as the recommendation concept in the future. In contrary to the other approach, it makes use of data gathered about the user's partner and their relationship. The team expects higher accuracy with this approach and thus, higher overall success.
