Below are some areas to focus on when setting smart goals for team members. This can be discussed in a 1 on 1 meeting, for example.
How much do you accomplish now? How do you measure your productivity? How can you increase your value output?
Do you tend to take on too many projects and make small progress on all of them? How can avoid distractions and focus on fewer projects end to end?
What are you really good it? What can you teach others better than anyone else? What skills and knowledge make you irreplaceable? In what new skills/knowledge are you excited about investing more time and energy?
How easy is it for peers to communicate with you? Do you slow down others or speed them up? Are you two steps ahead or one step behind? Do people come to you to ask questions? How can you make yourself easier to interact and communicate with?
