When a tree falls in the woods and no one is around to hear it, does it make a sound? Physics tells us the answer is yes. Likewise, does the question about project progress not asked have a consequence? Project managers might not have as tidy an answer as physics professors. But not knowing could leave a hole in our knowledge or in the knowledge of the team, increasing the potential for a mistake. For example, as a product owner it is important to understand the acceptance criteria for a story to know if it is ready to be fully accepted. In both the short and the long term, what we don’t know can hurt us.
