The good news is that there are loads of interesting models, but which model you choose to use depends on what you are trying to achieve.
If you want to give feedback on work-in-progress—a creation of some sort—you might want to take a look at Liz Lerman’s deceptively simple Critical Response Process or CRP.
This allows you to understand get a wider perspective about an individual’s thoughts, motivations, and creation(s) so that you can offer feedback that is honest, direct, and both motivating and helpful. Importantly, the feedback doesn’t slip into being cruel or unkind, thanks to the process.
