The phrase, “It’s just common sense,” is used quite often to describe conclusions or circumstances that are obvious to most people, at least those within earshot. However, W. Edwards Deming, a well-respected management guru and quality expert, famously said, “There’s no such thing as common sense. If there were, it would be common.” So, at least from Deming’s perspective, you have the answer to this article’s question. Moreover, you’ve probably seen any number of instances where common sense just doesn’t seem to have been applied, each instance lending credibility to Deming’s opinion. That said, let’s explore this further and perhaps try to begin to understand why he said this and why so often there are instances where common sense is not applied. Maybe it’s just not as common as it should be.
