The likelihood versus Impact filtering activity helps to prioritize items for further conversation.
Running the activity
1. Draw the likelihood versus Impact graph next to the canvas with many items.
2. Explain the graph.
What is the likelihood of this happening? Low, medium or high?
In case it does happen, what is the impact? Low, medium or high?
3. Grade each note from the canvas: get each note from the canvas, bring to the graph, mark it and bring it back to the canvas.
Below is a photo of this activity. On this instance, the facilitator was removing the items with low likelihood and low impact from the main canvas, and marking with one, two or three stars the items respectively with medium-medium, medium-high (or high-medium), and high-high likelihood and impact. After running this filtering activity, there were much less items for further discussion (and the next retrospective activity).
