Key Concepts

What your agent learns

Hypothesis-Driven Design

Frame design decisions as hypotheses: "We believe [this change] will result in [this outcome]. We'll know we're right when [this metric changes]."

Outcomes over Outputs

Focus on changing customer behavior (outcomes), not shipping features (outputs). Measure success by impact, not delivery.

Cross-Functional Collaboration

Break down silos between design, engineering, and product. Co-create solutions with shared understanding.

Design Studio Method

Run collaborative sketching sessions where the whole team generates and critiques ideas together.

Minimum Viable Product

Design the smallest experiment that tests your riskiest assumption — a landing page, Wizard of Oz test, or concierge MVP.
