The Lux Method
A one-week remote design sprint, with a Lux Score reading on Monday and the same reading on Friday, so you can see what changed.
The one-week sprint
The Lux Method is a one-week remote design sprint led by William Blake. It takes one specific problem from unclear to tested, and measures the difference with the same Lux Score reading at each end.
Teams and owners with one problem they can name in a sentence: sign-ups that stall, a flow people abandon, an offer nobody understands, a manual task that eats the week.
You do not need a large team: you bring the people who know the problem and can make a decision.
Most stuck projects are unclear before they are badly designed. Nobody has agreed what the problem is, what a better result looks like, or who it affects. The sprint settles that in a week, and tests the answer with people who are not on your team.
Three live sessions of two and a half hours, a build day that needs nothing from you, and a Friday test.
Monday · 2.5 hours live
You take the baseline reading, rate each of six lenses with evidence, set the sprint goal and pick the number that will show on Friday whether it worked.
Tuesday · 2.5 hours live
Lightning demos, concepts explored from the customer, owner, competitor and regulator points of view, and three wireframed flows.
Wednesday · 2.5 hours live
A vote, then the decider’s call. A storyboard and a test script. The scope is frozen.
Thursday · build day, mostly async
The chosen flow is built with LUXD’s design tokens, checked, and put on a preview link. A short walkthrough closes the day.
Friday · tests and a session
Five tests with people outside your team, the same reading again, the lens ratings again, and a recommendation: build, iterate or stop.
The Lux Score asks for the same things a good brief has. Bring:
Friday ends with a decision, not a deck. If the answer is build, you have a tested direction and a scope to build against. If it is iterate, you know which part to change. If it is stop, you have found out in a week.
How the reading works
The Lux Score rates six areas of your business from 0 to 10, and your lowest area is where the work starts. The four steps below are how the reading is used, in a sprint or across a longer project.
Step 1 · Read
Dim
Score six areas of your business from 0 to 10, free, in about three minutes. Your lowest area is where the work starts.
Step 2 · Focus
Lamplit
A free 30-minute call checks the evidence for your lowest area and the runner-up, because a self-score can move by a point. The one holding the rest back becomes the sprint goal, with a number, a deadline and the people it affects.
Step 3 · Light
Well lit
William designs and builds against that one goal, and treats your time, budget and tools as part of the brief from day one, so what he makes is something you can actually run.
Step 4 · Re-read
Daylight
Afterwards you score the same six areas again, with the same questions. You get both readings side by side, next to the real numbers that changed.
Six lenses
A full reading looks through six lenses that match the six areas of the Lux Score, each rated with evidence on Monday and again on Friday. Your Lux Score is how you see each area; the lens rating is what the evidence supports.
The Owner lens is the difference. A business with two hours a week can’t run something built for a team of ten, however good it looks, so William rates that honestly before anything gets designed.
Each lens is rated from 1 to 10 against what the evidence shows. The rating recorded is the lower of your number and what the evidence supports.
Three readings
Every reading covers the same six areas. Your Lux Score rates each area 0 to 10 as you see it; on a project, the lens rating (1 to 10) records what the evidence supports.
If the questions change between readings, the comparison means nothing. They don’t.
A score that rises is only convincing next to the measured change behind it: for example, conversion going from 4% to 7%.
William never shows a client’s reading unless they took it and agreed to it.
Bring the brief, or start with a reading. A written scope follows within two working days.
