One of the aims of expert knowledge management via information and communication technology is to improve the efficiency of knowledge transfer to non‐specialists, and to facilitate the implementation of service‐products that are adapted so as to be truly used. The aim of this paper is to describe an example in the domain of instrumental e‐learning.
Drawing on activity theory, this article describes a methodology that aims to guide the design process along the lines of the usage process.
The co‐design platform (CDP) allows the service designers and users to determine service‐product definitions together, to facilitate the emergence of their uses.
Some of the experiments are still in progress as the development is iterative.
To illustrate this method, the authors have designed and implemented an instrumental learning e‐service for guitar music (e‐guitare).
The CDP gives a greater understanding of the transformation of the tool (proposals) into an instrument (proven demand), which is essential to the process of supplying the demand.
