The challenge

A survey after every session in each group, separately for each trainer.

Participants named the following as most useful: communicating about change and working with doubts and resistance, adapting the conversation to personality type, and the FUKO and SPINKA conversation models. “The FUKO model will definitely make it easier for me to talk to the crew.” – participant in the difficult conversations training (2024)

Survey ratings on a 1–5 scale; the table shows ratings for the groups with a survey summary. Two sessions in 2024 were rated on the client’s 1–4 scale – both received the maximum score of 4.00.
