Failure cause

Failure causes are reasons why something didn't work or didn't turn out like it was supposed to. For example, if you try to bake a cake but it doesn't turn out well, the cause of the failure is likely that you put the wrong amount of sugar, baking soda, or maybe you burnt it too much. Failure causes can be anything that prevented you from achieving the result you wanted.
