I'm writing a review for a co-worker. This co-worker's weakness is they tend to over-explain problems and use a lot of words when few are required. Although they want to provide full context and lots of precise language, the message tends to get lost in the verbiage.
Being this is a co-worker, and my feedback is not anonymous, I want to express this concern in a tactful way. However, I'm struggling to express this in a way that doesn't sound like "you talk too much"
Are there standard ways of expressing this concern?
Update:
My employer has a standard peer review feedback process and this person has asked for feedback from me (and presumably others). The process explicitly asks the reviewer to identify a peer's strengths and areas for improvement. Although I could avoid discussing their weakness, I see that as reducing the value of the peer review process since there's no opportunity to improve.
