In the past I have introduced the concept of appreciative inquiry. Taking a little different focus, I would like today to talk about appreciative feedback. It is an insight that is offered with a positive and future-focused tone. The emphasis is on how to be more effective and productive in the future, rather than finding fault and placing blame for the past.
For a period of time when I lived in the US, I taught at North Central College in Naperville, Illinois. We had a sister institution in the next town known as Benedictine University. It happens that they have a wonderful summary web page about our topic that you can read here: https://cvdl.ben.edu/blog/appreciative_feedback/
Since a core aspect of appreciative feedback is making your feedback positive (showing appreciation for what was done well), you might also like to have a look at this article on “8 Examples of Giving Positive Feedback to Employees”.
I see nothing wrong with pointing out mistakes, but it should be linked to lessons for improvement and be as free as possible from playing “gotcha”. Feedback should improve skills while motivating the other person and building confidence and affirming trust.
