The document discusses how legacy content and code can accumulate over time in content management systems due to a lack of governance, clear guidelines, and cross-functional collaboration. It notes that both "content debt" and "technical debt" have the same root causes and solutions. The engineering team can help by focusing on user stories and desired outcomes rather than specific features, and by embedding themselves in cross-functional teams. This allows everyone to work towards common goals and prevent the buildup of both content and code that no longer meets organizational needs.
