Inspired by the ChaosEngineering of Netflix and the SimianArmy I developed a set of SRE Tests for Project Managers

Meet with your Team of Heads/Leaders/Managers, once a week for 20 minutes. Provide Drinks and Snacks. Prepare your GM sheets and Dices and Charakter Sheets.
Choose one from each stack, either by printing them out or rolling a dice for each.
