How-to: Consider and note the different reasons that your project may fail or stop based on the “BPESTLE” framework. Some areas of the framework will be more/less relevant for different ideas, so although each area should be considered, you don’t need to list ideas for each area. Next, circle the risk factor for each of the potential failure reasons. Finally, note different ways to test or mitigate the risk for each reason.
Purpose: This is useful for both identifying risks and predetermining areas of concern which people are likely to raise regarding potential projects. The showstopper analysis therefore makes sure that the idea has been considered from different angles and fits with your organisations risk attitude.
