Memory Load Reduction

Design systems that remember so users don't have to. Working memory holds roughly 4 items. Every piece of information the user must carry across screens, steps, or sessions is a potential failure point.

Core Principle

If the system can remember it, the user shouldn't have to.

Design Patterns

Persistent Context

• Show key selections throughout a multi-step flow (chosen product, plan, date visible on every step)
• Display running totals in shopping and financial contexts
• Keep the user's search query visible in results
• In multi-step forms, show a summary sidebar of completed steps
