Product Debt
The accumulated cost of past product decisions that were expedient at the time but create ongoing friction, confusion, or inefficiency. Product debt manifests as inconsistent UX patterns, unused features, and convoluted user flows.
Product debt is the product management equivalent of technical debt. It accumulates when teams ship features without fully considering long-term consistency, when deprecated workflows remain accessible, or when quick fixes to UX issues create inconsistent patterns. Over time, product debt slows development because every new feature must navigate around legacy decisions, and it degrades user experience as the product becomes harder to learn and use.
AI products accumulate product debt rapidly because the field moves so fast. An early AI feature built with one approach may become inconsistent with newer features that use more advanced models. Different AI capabilities might have different interaction patterns, confidence displays, and error handling, creating a disjointed experience. Growth teams feel product debt most acutely when onboarding new users, because accumulated inconsistencies make the product harder to explain and the learning curve steeper. Addressing product debt requires deliberate investment in simplification, standardization, and sometimes removing features entirely, which can feel counterproductive but ultimately accelerates both development and growth.
