One of my favorite ideas I've found since I've been blogging is the one I blogged about here called "Stop, Start, Continue."  Divide your staff into three groups and identify a single problem or question you need to address in your practice (or your life). 

Ask the first group to brainstorm and answer the question, "In order to _______, we need to stop doing _______."  The second group does the same with the  question, "In order to _______, we need to start doing _______."  Finally the third group answers, "In order to _______, we need to continue doing _______."

After all three groups have come up with a number of answers to their question, have everyone rotate and repeat the process two more times.  Get everyone together, review the answers, and then devise a plan to put the ideas into action.
