learning from feedback is crucial in consulting. Personally, I've had the chance to rotate across multiple teams / countires and gained a lot of feedback over the years.
I have been structuring my feedback depending on a few variables:
- Level of seniority (senior, peer, junior) >> a person's perspective changes depending on seniority, this will help you weight the feedback you receive accordingly
- Time spent together: how much time did I work with that person?
- Type of project we did together: was it an intense case (e.g. due diligence) or a longer project (>3 months)
- Type of feedback session (e.g. intermediate review, final review)
- Feedback Focus:where did the feedback focused on? was it about my speaking, reasoning, zero defect, etc ... if you could tag the feedback based on the areas where you did well / need to improve, that could also help you make a comparison in the future
- Time: remember to put a date next to the feedback, this will allow you to get a much better chronological view
A matrix could be one way of categorizing your feedback. But I would spend a bit more time in categorizing it with additional variables. For this reason, also having an excel with the categorization above and links to the respective documents could help.
Hope this answer helps!
