Band
A band is the range of ways a user could honestly describe what they're doing right now. Someone driving to work isn't fixed on a single description: "commuting," "driving," and "staying alert in traffic" are all true at once and all feel like what they're doing. The range has natural edges. Too broad, like "contributing to the economy," and they wouldn't claim it as their current activity; too granular, like "pressing the accelerator with my right foot," and it sits beneath what they're consciously tracking. The band also shifts with attention, narrowing under stress and widening during reflection.
Definition
The range of scope-levels on the user's stack that their awareness spans at a given moment.
What bounds the band
The band has two edges:
- Upper edge: scope-levels the user wouldn't recognize as describing what they're currently doing. The activity may serve those larger pursuits, but they aren't the user's framing of the present moment. For someone driving to work, "contributing to the climate crisis" is technically descriptive but outside the band.
- Lower edge: mechanical detail beneath the user's conscious foreground. For the same driver, "exerting gentle pressure with my fingertips on the steering wheel" is accurate but beneath what the user would recognize as what they're doing.
Within the band, several scope-levels are simultaneously legitimate. The driver is aware of "commuting to work" and "operating a car" and "maintaining vigilance for safety" at once. Communication forces compression to a single scope-level when speaking, but the underlying awareness spans multiple.
How the band shifts
The band moves with the aperture of attention. Under stress it narrows — after a near-miss, the driver's band might compress to "my foot SLAMMED on the brake." During reflection it widens. It drifts based on what becomes salient. A user's self-account in research will often drift across scope-levels within a single interview, and that drift reveals the band their awareness currently occupies rather than multiple uncoordinated activities.
Band-matching as design work
Messaging at scope-levels inside the user's band lands as recognition — "yes, that's what I'm doing." Messaging on either side lands as misalignment, even when the description is accurate. "I see you're getting your invoice prepped to be sent" is band-matched to a user working on an invoice. "I see you just typed using your keyboard" is still on the user's stack but beneath the band of conscious activity, and it reads as strange rather than as recognition.
Reading the user's likely band is part of reading the user. Matching it runs through copy, default selections, headline framing, and any other element where the offering describes back to the user what they're doing.
Dependence on intent prediction
Band-matching's recognition effect amplifies whatever interpretation it's built on. Larger-scope messaging compresses more interpretation into the framing — assuming what kind of pursuit the user is on, not just what step they're at. When the underlying intent prediction is correct, larger-scope band-matching produces strong recognition. When the prediction is wrong, the same recognition effect makes the error more conspicuous rather than less.
A system that detects an Airbnb booking in Europe and messages "get fully prepped for your big business trip" is band-matched to a confidently-named intent. If the user is going to a wedding, the confident framing makes the misalignment land harder than a smaller-scope message would. Smaller-scope messaging on uncertain intent claims less and fails more softly when prediction confidence is low.
Example
A freelance designer is working in the offering's invoicing screen. Within the band right now: "filling out this invoice," "billing my September clients," "getting paid for the work I did." Outside the upper edge: "running my business," "building financial stability." Outside the lower edge: "clicking the line-item field," "typing the dollar amount."
A status message that says "Invoice draft saved" is band-matched. A message that says "Building your business, one invoice at a time" overshoots the band — the user might agree it's true, but they don't recognize it as describing what they're doing right now. A message that says "Your keystroke was registered" undershoots — accurate, but beneath the user's conscious framing of the moment.
