If your team wants to have better strategies to manage large and risky changes, improve their slicing skills, or practice techniques as parallel changes, branch by abstraction, look at this Small Safe Steps workshop.
I have prepared information so that anyone can easily facilitate the workshop.
Please use the material, run the workshop, give me improvement feedback. And if you need advice on running or adapting it, contact me, and I will be happy to help.
