Four short questions. Specific, honest examples make feedback most useful.
“When faced with a challenge or new project, how does this person step up to lead, motivate others, or drive results?”
“What specific skill, domain, or task is this person exceptionally good at, and when should colleagues go to them for help?”
“How effectively does this person communicate, partner with other departments, and follow through on commitments?”
“What is one area of improvement or actionable advice that could help this person increase their professional impact?”
