The document discusses the concept of "wicked problems" as described by Horst Rittel and Melvin Webber. They define wicked problems as problems that are difficult to solve because they are unclear or have many interlinked issues. Rittel and Webber outline ten key properties of wicked problems, including that they have no clear solution, no way to test solutions, and solutions to one aspect may reveal or create other problems. The aim in addressing wicked problems is to improve the situation, not find an absolute truth or answer.
