Execution – actually having the team get things done– requires people to :

1. Say what they will do 
2. Mean it (be committed)
3. Do it

Everyone likes to do #1. Only some do #2. Great teams also do #3.

This must have been in my subconscious when I asked the team to switch reporting continuous learning goal progress to the Friday stand up instead of one on one.
