Mistakes that go unreported out of fear are a waste for two reasons. First, the team never gets to truly resolve the problem as mistakes are never owned and discussed in a way that finds a solution. The team is therefore tasked with searching for a cause and also working around what seems to be a hole in the bucket. The second reason unreported mistakes are wasteful is that the team misses out on a moment to look back on and learn. In a sense the mistake is wasted as it gets swept under the carpet. This waste is reflective of a leadership culture that governs on fear of embarrassment and not incremental development.
