Every time I run in to something that gets in my way, slows me down or just annoys me I write it down on a card. If I run in to the same problem again - I add another notch to the card (like a tally). A colleague has a principle of Three Strikes and You’re Out - that is, if you come across the same problem three times you have to fix it. I also find it useful to take these cards along to retrospectives or stand-up meetings. Fixing these things that get in the way has really had a positive effect on productivity and made the team more interested in fixing bad things rather than taking the extra time and effort to work around them.

Having a further look around I found a fellow James-Shore-fan, who had come up with a interesting idea to be used at the end of a retrospective - a ROTI (Return On Time Invested) histogram.
