‘The devil is in the details’ is a phrase commonly used to describe the importance of addressing the details of a grander plan. While seemingly insignificant, it may contain hidden problems and threaten the overall feasibility of the program.
How often are the minor elements the ones that seemingly unravel the best of intentions? What may typically transpire is that something of significance is ignored and considered insignificant by the creator.
While we may have the best intentions, we cannot know what others, including customers, partners, and a broader community, need or want unless we ask them. It is usually the seemingly small things that are the ones that are of importance and disrupt all the good.
