R1 — Most businesses benefit from AT LEAST ONE of the four working-surface capabilities, NOT all four; match the capability to acquisition / service mode

Rule: The defensible claim is that most businesses benefit from at least one working-surface capability, matched to how they acquire and serve customers — never "all of them."

Why: ~27% of US SMBs run with no website at all and many thrive on word-of-mouth (Zippia (via Wix, 2026) — 73% of US small businesses have a website; ~27% (more than 1 in 4) do not, B2B Lead Finder — website non-adoption rates 45–56% in some trades; 50–65% in emerging markets, Zippia — website-less SMB owners' reasons: 27% "not relevant to my industry"; 26% cite cost). A sole operator booked out on referrals may need none of the four (Capability 1 — structured, queryable data: content stored as records with fields, types and relationships so it can be filtered, sorted, searched, and assembled on demand, Capability 2 — interactive functionality: the visitor supplies input and the site returns a computed or looked-up result (calculator, quote, search, booking, configurator), Capability 3 — live or frequently-updated data: content whose value depends on currency (availability, pricing, status, hours, inventory) refreshed on a cadence rather than written once, Capability 4 — account / state: the site remembers who the visitor is and what they have done (login, saved items, order history, progress) so returning visitors resume rather than restart). The capabilities are independent and should be matched to business type, not bundled as a checklist.

How to apply:

• First scoping question: how does this business acquire customers? Word-of-mouth-only is a legitimate end state — don't push a working surface that doesn't serve the acquisition mode.
• Pair with R7 — Match the working-surface capability to the business type: booking + live availability for trades, calculator / assessment for consulting, queryable products + account for retail for the per-business-type guidance.
• Honest framing in proposals: "your customers do X; the capability that serves X is Y; the other three are not required."
