The document discusses different types of problems - simple, complicated, and complex - and strategies for dealing with complex problems. It notes that complex problems cannot be clearly defined or solved, and are better understood through the process of addressing them. Three common strategies for complex problems are discussed: authoritarian, where one person defines the problem; collaborative, where multiple stakeholders work together; and competitive, where many solutions are tried simultaneously. It concludes that the appropriate strategy depends on the complexity of the problem, and designers must recognize when they are dealing with complex problems to avoid failed projects.
