During performance review season, most organizations encourage setting “personal” or “professional” goals along with other business goals for a period. But developmental goals are business goals too. Don’t think of these as “icing on the cake” or “nice to have.” Think of them as a strand twisted into the rope of the goals of the organization or team. “More effective at Collaboration” or “less harsh with peers/direct reports” are easy base hits, but you can and should point to some predictable business outcome.
And BTW, going to a leadership class is not a goal.
