AN OPEN ARCHIVE OF DECISION-MAKING / 001

The evidence
of making.

The finished thing tells you what survived. The casefile tells you what was assumed, what was rejected, what became possible—and what still isn't known.

Examples are openly labelled illustrative. No invented results or unverified performance trophies.

Good work is not
magic. It is a series
of legible choices.

When we publish only outcomes, we lose the fascinating middle: the options we considered, the constraints that actually mattered, and the evidence that challenged our favourite ideas.

The Evidence of Making treats work as an inquiry. Here the question is not “How impressive does this look?” but “Can we inspect how the decision was made?”

INSPECTION WINDOW01 / 05
THE HYPOTHESIS

Name the change you hope to make.

A good starting point is a claim that could turn out to be wrong. Say whom the work serves and what they should be able to do.

“A visitor should be able to discover a useful idea without learning our interface first.”
01 / THE ARCHIVETHREE STUDIES IN MAKING

Open the casefiles.

Three illustrative investigations adapted from the original concept. They are worked design examples, not independently verified project histories.

WEB ARCHITECTURE • DECISIONS UNDER CONSTRAINT

A website that can wear many faces.

How do you let an interface transform wildly without duplicating its content or abandoning the visitors who need the simplest version?

THE TENSION
Expressiveness vs. consistency
STRATEGY
One semantic source, multiple presentations
Inspect the reasoning

Hypothesis PROPOSED

A shared content model can enable ambitious presentation modes without multiplying editorial maintenance.

Alternatives considered ILLUSTRATIVE

A — Independent pages: maximal freedom, but duplicated content risks drift. B — Shared content: more consistent editorially, but increases interface-state and regression-testing complexity.

Accepted cost

Every additional mode multiplies the combinations worth testing: keyboard paths, 360px reflow, contrast, reduced motion, and navigation continuity.

Evidence required NOT YET CLAIMED

A repeatable cross-mode task test, accessible navigation review, and measurements recorded on named devices. Do not infer “0ms CLS” or “60fps always” from a prototype.

TRY THIS: If your most spectacular mode broke on an older phone, what experience would you preserve?

INTERACTION DESIGN • BROWSER LEARNING

Teaching a browser to teach.

A keyboard-learning micro-experience prompts a deceptively tricky question: how much JavaScript is genuinely necessary to make a lesson comprehensible?

THE TENSION
Custom control vs. native predictability
STRATEGY
Semantic controls, testable state changes
Inspect the reasoning

Hypothesis PROPOSED

For one bounded learning interaction, HTML controls and a small state model may be enough to support clear, predictable use.

Alternatives considered ILLUSTRATIVE

A — Framework-led: useful for rich shared state and larger teams, but adds build and dependency choices. B — Native-first: reduces runtime complexity, but requires careful manual testing of state transitions.

Accepted cost

Native-first does not eliminate accessibility work. State announcements, keyboard focus, error messages and actual learning outcomes still need evaluation.

Evidence required NOT YET CLAIMED

Observe participants completing a comparable task before and after the lesson; separately audit keyboard and screen-reader interaction. “100% ARIA compliant” is not an honest substitute for this work.

TRY THIS: Would you rather ship one reliable lesson today or five animated lessons nobody understands?
FILE № 003ILLUSTRATIVE
PHYSICAL & BRAND NARRATIVE • FRAGRANCE

How do you show something you cannot show?

A screen cannot transmit a perfume. It can, however, offer clues: a literal description, a careful metaphor and the freedom to interpret for yourself.

THE TENSION
Clarity vs. evocative storytelling
STRATEGY
Literal notes + optional visual translation
Inspect the reasoning

Hypothesis PROPOSED

Typography, pacing and illustrative colour may help someone imagine a scent journey when explicitly presented as metaphor, not as a measurable reproduction of smell.

Alternatives considered ILLUSTRATIVE

A — Pure product realism: precise-looking bottle imagery, but little sensory explanation. B — Evocative interaction: emotionally resonant, but vulnerable to ambiguity and culturally narrow associations.

Accepted cost

Metaphors vary by person. A thoughtful interface must still offer plain text, work without sound and avoid claiming that a colour universally evokes a scent.

Evidence required NOT YET CLAIMED

Ask participants whether they can separate factual note descriptions from artistic interpretation. Include different sensory preferences and an entirely non-animated route.

TRY THIS: What part of your creation is intrinsically impossible to demonstrate—and how can you tell the truth about that limit?
02 / CHOOSE YOUR TRADE-OFF

Make the call.
Face the cost.

Six fictional project dilemmas. Two defensible choices each. No manufactured right answer—only consequences worth examining.

SCENARIO 01 / 06
FIELD SIMULATION / FICTIONAL

A brilliant mode, an unreliable phone

A striking animated interface works on your machine. On older phones, visitors cannot reliably reach the article beneath it. Launch is tomorrow.

The point is not to win. It is to notice who bears your decision's cost.
