The iterative approach to training design consists, as the name suggests, of designing training courses. It also makes it possible to develop a training path. These training courses are designed in such a way that adjustments can be made easily. They also make it possible to carry out transformations and to continue to enrich them according to the evolution of different needs. It should be noted that in order to bring up relevant data in order to make them evolve, it is imperative to pay particular attention to the user questionnaires. The same applies to their analysis.
