Just like the “I like / I wish / How would it be if …” method, the “Plus or Delta – method” classifies the feedback into categories, thus sorting it – and thus it can be discussed more constructively.
The only difference is that there are two categories here. Under “Plus” you collect the feedback points that the team noticed positively and would like to keep.
Under “Delta” then come the points that should be reconsidered or even changed in the future.
One advantage of this method is its universal applicability, i.e. it can be used for ideas, activities, prototypes and marketing measures.
