How do I read the Flow board?

Steps

1. To open the Flow board, open Board and the tab Flow, then pick a release.One column per stage of the main process, with the release's cards in them.
2. To read where a card is, look at its column.A card sits in the stage its least advanced open task has reached. A card whose work has reached no stage yet sits under No stage evidence.
3. To see where work stays longest, read the line above the columns.Bottleneck: names the stage whose cards have the longest median time in that stage, counted over the cards in it now. No bottleneck measured means the cards there have no measured time yet; with no cards there is no line.
4. To see the work in human acceptance, read the line In human acceptance: above the columns.The number of cards a tester is checking on a test machine, then each tester's name with their count. A tester with no cards is left out. The line takes you to the S9 column.
5. To read one card, open it.The card panel opens beside the board; see the next card in this guide.
