Implementation / working method :

Interactive, one-day, face-to-face course. Powerpoint support will be shared at the start of the course in paper and digital formats.

A questionnaire will be sent to trainees before the course in order to adapt the course content to participants' expectations as far as possible.

A course evaluation questionnaire will be distributed to participants at the end of the course.
