Atlas · DS151 · Interaction principle: Focus

Task-First UI

Arranges components around the user's main tasks.

• Status in 2026: Established. Documented and in wide use.
• Trend 2027 to 2030: Rising (an editorial projection, not a forecast).
• The term: Known technical term or standard.

Definition

Arranges components around the user's main tasks.

Traits

• specific CTA
• few steps

Typical settings: Fintech, industry, services.

When to use it, and when not

Consider it when the task and motivation match: outcome-oriented people. Typical settings: fintech, industry, services.

Be careful when the risk below would hurt the main task: secondary flows are neglected.

UX risk and how to reduce it

Risk: Secondary flows are neglected.

Mitigation and accessibility: Map alternative journeys.

How to check: Test a prototype against a plain baseline on a real task: completion, time, errors, comprehension, accessibility and preference, segmented by context rather than by stereotype.

Evidence

Indirect: the sources support underlying principles, not a preference for this style.

The sources below support the principles that apply to this term. None of them shows that this style works better or is preferred.

• Hassenzahl 2004 (Supported): Pragmatic and hedonic qualities.
• Baymard Institute 2025 (Preliminary): Checkout flows in e-commerce.

Heuristic scales

Relative editorial judgements from 1 to 5. They are not results of a study and not a measure of quality.

Visual complexity heuristic

1 / 5 (1 is few visual elements, 5 is many layered elements)

Expressiveness heuristic

1 / 5 (1 is restrained, neutral, 5 is highly expressive)

Information density heuristic

3 / 5 (1 is sparse, 5 is dense)

In our library

No design-style recipe in @codeatlasdev/ui implements this term yet. You can still build it from the --ca-* tokens: see Theming.

Paste this into a coding agent. It carries the trade-offs, and asks for a baseline to compare against.

Design this interface in the "Task-First UI" direction (interaction principle, focus): Arranges components around the user's main tasks.
Visual and interaction traits to use: specific CTA, few steps.
Main UX risk: Secondary flows are neglected. Mitigate it: Map alternative journeys.
Keep it accessible to WCAG 2.2 AA: contrast, visible focus, keyboard operation, 24 px minimum targets, reflow at 320 CSS px and reduced motion.
Keep the content, hierarchy and behavior the same as a plain baseline so the two can be compared. Do not claim the style performs better; the choice should be validated with users.
