WYSIWYG may not be true for all IT systems. What you see may be more than what you actually get. As a Product Owner, you have to be very careful to not deceive yourself. The latest iteration of your product may be shiny and new — but all may not be well. Because of the hidden debt in your product and your team. Shortcomings that may haunt you — perhaps from day one or usually in a the slightly longer term. Shortcomings that you should be aware of, do something about and in the future should try to prevent altogether.
