Product Principles
A set of guiding beliefs that shape how a product team makes decisions. Product principles codify the team's values and trade-off preferences, enabling decentralized decision-making that remains consistent with the overall product direction.
Product principles are most useful when they express a genuine preference between two reasonable alternatives. A principle like we prioritize simplicity over completeness tells the team how to resolve the daily tension between adding features and keeping the product approachable. Principles that no one would disagree with, like we build great products, provide no decision-making value.
For AI product teams, explicit principles are essential because AI introduces novel trade-offs that traditional product principles may not address. Principles like we show AI confidence levels transparently, we always provide a manual fallback, or we optimize for user trust over engagement guide hundreds of daily decisions about how AI features behave. Growth teams benefit from clear principles because they constrain experimentation to approaches consistent with the product's identity. A principle that prioritizes user trust, for example, rules out dark patterns that might boost short-term conversion but erode the foundation of an AI product's value proposition.
