As an analogy to business, sometimes the best thing is to do nothing. Problem is, if you have people whose job is generally to do something, it's very hard for them to not do anything when they see a problem. Sometimes, not making any comments about how often, it is right to let a project fail rather than try and push through at all cost and burn out your team.

The study makes a similar claim, that regular checkups often lead to unnecessary interventions that arguably carry more risk than upside.
