What is Sequential IA?

Sequential IA guides users through content in a specific linear order—step 1, step 2, step 3. Users move forward/backward but can't skip around freely. Common in onboarding, checkout flows, multi-step forms, tutorials. Reduces cognitive load by focusing on one step at a time.

When Should You Use This?

Use sequential IA for processes with required order: onboarding (welcome > setup > first action), checkout (cart > shipping > payment), multi-step forms, tutorials, or workflows where context from previous steps is needed. Always show progress (step 3 of 5) and allow going back. Avoid for exploratory content or when users need to jump between steps.

Common Mistakes to Avoid

• •No progress indicator—users need to know how many steps remain; show stepper
• •Can't go back—users need to fix mistakes; always allow backward navigation
• •Too many steps—>5 steps and completion drops; consolidate when possible
• •Forcing linear when unnecessary—if steps are independent, use tabs or accordions
• •No save/resume—long sequences need ability to save progress and return later
