3. Detailed design of technical solutions and usage scenarios

This stage is technical, and calls on methods specific to your design field (e.g. mechanics, electronics, etc.). However, technical design must take into account environmental requirements, and possible interactions with other instruments and users.

The user's goal must be described and formalized. Nevertheless, the list of goals and tasks obtained during the analysis of step 1 is likely to evolve. Choose a duration for this phase, and schedule the experimentation sessions, which should be carried out in parallel with the "conceptual design" phase in the technical design process.

Let's take the surgeon's example again: you develop the new surgical instrument based on his needs (step 3 in the figure).

The figure below illustrates a progress process based on the example of a surgical instrument design project and its...
