I intend to add to this post over time with those tricks I want to remind myself before walking into a meeting.
Pearl Metaphor: Iterative development is like a pearl starting with sand and adding Calcium Carbonate. Instead we add functionality and usability over time.
Construction Metaphor: Moving a wall 3 inches to the left doesn’t cost a lot in terms of materials – sure you need a few more nails and maybe a few more 2x4s but it is going to cost a lot in man hours. Same is true for many late changes to a program.
