Team Business[edit]


Mid-year check-ins[edit]

A basic check-in: Go over what we hoped we'd do when we talked back for annual review

Then, the outline from T&C:

  • Celebrate accomplishments (highs):
  • What can we learn from (lows):
  • What goals or projects have been completed? What went well, what could have been better?
  • What goals/responsibilities are still ahead? Is any support needed to help get them done? Does any work need to be adjusted (due to departmental/organizational change)?
  • Any peer feedback wanted or given? (Feel free to do this casually via email or conversation.)
    • [Greg: Let me know if anyone wants to do some kind of "ask your peers for feedback", I can set something up.]

Please come prepared to talk about those items; I'll be filling out a document we can look at during the meeting, just for our records. They are not shared with T&C (they will only be checking in with managers to verify the check-ins happened, not what the content was).
