The test is whether each piece serves the user’s current decision

What it is

The actionable test of aesthetic and minimalist design is not “less,” “empty,” or “beautiful.” Ask of every element: what decision does it help the user make at this task point? The answer may be choosing, waiting, excluding risk, correcting an error, or confirming permission; content without an answer needs deletion or relocation.

Why it happens

Information value depends on task relevance, not absolute quantity. The same field is a necessary constraint at submission and noise in a browse list; the same warning prevents an action beforehand but may have only log value afterward. Using the current decision as the baseline makes deletion, merging, collapse, role-based display, and hint level comparable.

Where it stops holding

The current decision includes later recovery and audit, not only the immediate button. Relevance changes by role, stage, and exception path; no single persona represents all needs. Regulation, contracts, and medical contexts may require information useless in the ordinary flow. Define each role’s set of decisions instead of seeking one universal page.

Applying it

• Use a task map to list each page’s primary decisions, reversibility, and required evidence.
• For every element, record the decision supported, the mode of support—compare, confirm, exclude, recover—and the minimum presentation level.
• After deleting, collapsing, or role-moving content, rerun tasks and check that decision quality stays equal or improves.
• Add the information-decision table to redesign acceptance so new elements require a task rationale.
