A café concept often starts with an attractive picture: a menu, a room and the people who might enjoy them. Customer research asks what those people are trying to do before asking whether they like the picture. A commuter collecting a drink, a worker carrying breakfast and two friends meeting after lunch may pass the same frontage while needing very different things.
The useful outcome is a clearer set of assumptions and a next test. A handful of encouraging conversations cannot establish market size, daily transactions or a reason to sign a lease. This guide keeps reported experience, direct observation and the owner's interpretation separate so each decision rests on evidence of the right kind.
Choose a question that could change the concept
Start with one customer occasion and one uncertain assumption. For example: do nearby workers need somewhere to buy breakfast before their commute, or do they already eat elsewhere? That question can affect opening hours, the offer and the service format. Asking whether people like cafés is too broad to resolve those choices.
Write down what would challenge your assumption as well as what would support it. If people consistently describe bringing food from home, that is useful evidence even when they say the proposed interior looks lovely. Keep the concept sketch for later in the conversation, after understanding the existing routine.
Recruit around the occasion, not just your contacts
Describe whom you want to hear from, where you can appropriately reach them and which times matter. Friends and suppliers can offer useful opinions, but their circumstances may differ from the intended customer. A conversation during a quiet afternoon tells you little about an early commute unless that routine is specifically discussed.
Invite participation without pressure and explain the purpose and intended use of the notes. People can decline or skip a question. Use anonymous participant references in the shared worksheet and avoid collecting names, contact details, employers or other personal information that the decision does not need. Arrange any agreed follow-up through an appropriate restricted process.
Ask about the last relevant experience
Use prompts such as: when did you last buy breakfast on a working day; where did you go; what did you choose; and what made that option convenient? Follow the sequence, including travel, waiting, carrying food and paying. Leave room for an answer that does not involve buying anything.
Avoid building the desired answer into the question. 'Would a beautiful café solve your breakfast problem?' assumes both a problem and a solution. A more useful prompt asks what was difficult, if anything, about that particular morning. Keep a short core question guide so conversations address the same decision, while allowing relevant follow-up.
Record whether a statement describes a past event, a current preference or a hypothetical intention. A remembered purchase is still self-reported evidence. Watching a person enter a nearby shop does not tell you what they bought or why. Label what is known and leave the rest unresolved.
Worked example: four different occasions
A fictional owner is considering a seated weekday-breakfast café. Four voluntary conversations produce the records below. These are invented illustrations of how to organise notes, not actual customer interviews or a recommended sample size.
The owner has not discovered four votes for one concept. The first record raises a pickup question, the second challenges the assumption that breakfast is purchased, and the last two concern different occasions. None establishes the number of people who would buy from the proposed café.
| Anonymous reference | Reported recent occasion | Question for the concept |
|---|---|---|
| P01 (fictional) | Collected coffee while travelling to work; described little spare time | Could an appropriate pickup offer fit that route and time? |
| P02 (fictional) | Brought breakfast from home and ate at the desk | Is there a purchase need, or is the current routine satisfactory? |
| P03 (fictional) | Met a colleague for coffee in the afternoon | Does this support a different occasion from weekday breakfast? |
| P04 (fictional) | Sat with friends over a weekend meal | What evidence is still missing for weekday trade? |
Keep contradictions beside the emerging pattern
Group notes by the decision they inform: timing, route, current alternative, purchase trigger or difficulty. Preserve the participant reference and original note behind each summary. One conversation may inform several themes, so a count of theme mentions is not a count of different customers.
Put conflicting evidence in the same review. If some people value seating and others need to leave quickly, investigate whether these are different occasions rather than averaging them into a vague ideal customer. Record which people, times and situations have not been represented. Do not turn a convenience sample into a population percentage.
Choose a small next test with a clear limit
In the fictional example, the next step could be further conversations about the commute and observation of the relevant route at the stated time, where appropriate. A separate test might examine whether an intended pickup process can deliver the proposed offer. Record the question, scope, owner, evidence to collect and decision it will inform before starting.
If a later test involves serving or selling food, it must operate within the permissions and controls required for that activity. Customer enthusiasm is not approval to trade. Keep any operational trial separate from the research record and preserve the conditions under which people evaluated the offer.
Update the plan without turning opinions into sales
Record whether the evidence changed the customer occasion, offer, service format or remaining questions. Link the decision to the relevant notes and keep the earlier assumption visible. A decision to investigate takeaway breakfast is a research direction, not a validated forecast.
When building a sales forecast later, identify the additional evidence required for traffic, conversion, actual purchase behaviour and capacity. Do not multiply interview enthusiasm by local population to create daily orders. Use customer research to improve the questions the financial and operating plans must answer.
What small-business research guidance supports
The US Small Business Administration distinguishes existing market information from direct research with consumers. Its market-research guidance identifies interviews and other methods for learning about a particular audience and its alternatives. That general distinction supports this approach. The café prompts, fictional records and decision worksheet are original; US funding programmes, demographic datasets and legal requirements are not applied here.

Customer research and assumption review
The Customer Discovery worksheet is a manual research record. Define the occasion and assumption, prepare a question guide, record anonymous evidence and its type, retain contradictions and coverage gaps, and assign the next test and decision. It has no demand forecast, customer score or automatic concept approval.
