Note that you can employ the structure in Table 3.1 independently of your product backlog tool, for instance, by appropriately arranging paper CARDS on a pin board, whiteboard, or the office wall.

The goons grab Michael and pin him on a table. One of the goons removes Michael's boot, exposing his foot and then grabs a pair of pruning shears.

Now, drag a "Find Deviations" operator onto the canvas next to the table source, and connect the output pin of the table source with the input pin of "Find deviations".
