Set up a 'retrospective mailbox' at the beginning of the iteration. Whenever something significant happens or someone has an idea for improvement, they write it down and 'post' it. (Alternatively the 'mailbox' can be a visible place. This can spark discussion during the iteration.) Go through the notes and discuss them. A mailbox is great for long iterations and forgetful teams.
Visualize promise and ease of possible courses of actions to help pick Source:
Reveal a previously drawn tree. Hand out round index cards and instruct participants to write down the actions they would like to take - one per card. When everyone's finished, collect the cards, shuffle and read them out one by one. Place each 'fruit' according to the participants' assessment:
Is it easy to do? Place it lower. Hard? More to the top.
Does it seem very beneficial? Place it more to the left. Value is dubious at best? To the right.
The straightforward choice is to pick the bottom left fruit as action items. If this is not consensus, you can either have a short discussion to agree on some actions or dot vote.
Gauge participants' satisfaction with the retro on a scale from 1 to 5 in minimum time Source:

Put sticky notes on the door with the numbers 1 through 5 on them. 1 is the topmost and best, 5 the lowest and worst.When ending the retrospective, ask your participants to put a sticky to the number they feel reflects the session. The sticky can be empty or have a comment or suggestion on it.
