Everyone likes a happy ending and this applies in development work too. Quite often, we have the tendency to showcase our successes through best practices that are upheld as evidence that a particular approach works. But what about those instances when we may have made some mistakes along the way or failed outright? Humans have a tendency to focus on successes rather than failures.
"This [handling of failure] is difficult for us to do well because we have strong human bias to value successes more than we value failures. In most organizations failure is stigmatized and nobody wants to be associated with it…..Unfortunately this produces some dangerous side-effects. Since improbable failures have high information content, it is important to communicate information about failure quickly and widely throughout the organization. To the extent that we hinder the flow of this information, we will force people to reinvent failures that we have already experienced, and that generates no useful new information."
