Productivity can be measured in raw output but it can also be very subjective, it is easy to fall into the trap of thinking (or having your boss tell) you have not been productive during a day when actually you have. Productivity needs to be measured over weeks or better months. An hour, a morning or a day is too small timeframe to access how productive you have been. I write down what has been improved, 5 mins at the end of the day. Code I have developed, customers I have helped, sales I have made. It's a nice list to look at later. Easy to forget what you have improved. Writing down distractions also helps me to look how to eliminate them.
