Steal My (Exact) Script For Criticizing Clients Without Getting Fired https://medium.com/swlh/non-toxic-constructive-criticism-779a59d09ec4

I don’t like yes/no questions. It’s just too easy for a client to lie with them mostly because they feel embarrassed about something not being perfect.

A good formula I like to use is:

1. What’s on your mind?
2. What else? (3-5 times until you’ve totally cut their cognitive load.)
3. Zoom in on the problems with more what questions.
4. Now they are ready to listen to you and not think about what they want to say.
5. Give 2-3 solutions. Let the client choose. Clients love feeling like they are in control throw some pros and cons along the way.

Thanks again for the brilliant question! Feel free to follow up. :-)
