Design debt doesn’t appear overnight. It builds up slowly through shortcuts, rushed releases, and quick fixes that were meant to be temporary. When caught in the moment, these choices feel like momentum. But over time, they pile up into real problems: inconsistent user interfaces, duplicated patterns, hard-to-navigate workflows, and teams who feel stuck.
