AI First

AI in my design practice

I use AI across four stages: understanding the problem, exploring ideas, delivering designs, and evolving the design system. I set the context and review every decision.

Understand and organize

Understand the problem before exploring solutions.

AI support: Summarizing meetings, organizing reference material, and drafting questions, requirements, and hypotheses.
My responsibility: Defining the problem, verifying information, and building a deeper understanding with users and stakeholders.

Explore and prototype

Make ideas tangible so design decisions can be evaluated.

AI support: Generating UI options, responsive layouts, and prototypes based on the design system.
My responsibility: Guiding exploration and reviewing user flows, hierarchy, and consistency before taking a design further.

Review and deliver

Give engineering the detail needed to build the experience.

AI support: Documenting component states, UI copy, user flows, and implementation specifications.
My responsibility: Reviewing the details with engineering and checking that the design meets the project’s needs.

Manage and optimize

Build on a consistent foundation of reusable components.

AI support: Building and maintaining the design system, identifying inconsistencies, and suggesting improvements to components.
My responsibility: Creating AI skills and agents to help manage changes and speed up delivery. I review their suggestions and prioritize component reuse.
