Based on social interactionism, this article aims to report and analyse part of a university advisory job on instructions for textual production at academic levels, in which consultants and teachers focused on the elaboration of didactic material for university students, more specifically, the production of a didactic sequence for a genre, the `critical review article'. The different steps and analyses carried out to put the project forward are discussed together with the theoretical and interactional problems that had to be faced, so as to finally raise the conclusions about the consulting job itself and the suggested procedures for the design of the didactic material.
