DrinkOwner of a 15–40 seat café or drinks shop

When several people make the drinks, I want every cup to come out the same, so customers do not have to guess who is on the bar today.

Khi có nhiều người cùng pha, tôi muốn mỗi ly ra giống nhau, để khách không phải đoán hôm nay ai đứng quầy.

Job context

Who
An owner with two to four rotating baristas
When
Every shift, most visible at peak
Trigger
A customer saying today's cup is different from yesterday's
Situation
The recipe lives in the maker's hands, not on paper
Constraints
Staff churn constantly, and peak hours leave no time for measuring

5 Pains

  • Free-pouring makes every person different

    High

    A small difference in ingredients makes a large difference in taste.

    Root cause: Peak-hour speed is prioritised over precision

  • A new batch of beans changes the taste

    Medium

    The same recipe yields a different result when the supply changes.

    Root cause: Nobody recalibrates after each batch

  • Nobody tastes before serving

    High

    The only check is the customer.

    Root cause: Tasting costs stock and time, and nobody owns the task

  • Training a new hire takes weeks

    Medium

    And by the time they are steady, many have left.

    Root cause: Hand knowledge only transfers by standing next to someone

  • Customers do not complain; they just stop coming

    High

    One bad cup is not worth mentioning and is enough to change a habit.

    Root cause: The cost of complaining exceeds the value of one drink

5 Desired Outcomes

  • Every cup is the same regardless of who made it

    Functional
  • Recalibrate when the supply changes

    Functional
  • Have a check before the cup reaches the customer

    Functional
  • A new hire gets it right within a few shifts

    Functional
  • Feel settled when away from the shop

    Emotional

5 Existing Solutions

A solution is not the same thing as a product — a customer can hire a behaviour or a workaround too.

  • A scale at the bar

    Product

    Turns a feeling into a number — the cheapest effective fix.

  • Automatic dosing equipment

    Product

    Solves it outright, at a price beyond most small shops.

  • Recipe cards at the bar

    Workaround

    Owners build the standard the trade does not publish.

  • Owner tastes at random during a shift

    Behaviour

    The only check that exists, and it disappears when the owner does.

  • Ask a regular whether today's cup is right

    Behaviour

    The shop's real feedback channel, running on relationship rather than process.

2 Opportunity Gaps

  • The final quality check is the customer — a party not paid for the role and with no way to report back.

    Why existing solutions fail: A check needs a second palate that knows what right tastes like, and a small shop has one, currently making the drink.

    Potential opportunity: A quick check needing no expert palate — a number on a scale, a time mark.

  • Customers do not complain about a bad cup; they simply stop coming, so the most important quality signal is never recorded.

    Why existing solutions fail: The cost of speaking exceeds the value of one drink, so silence is always rational, and every feedback system depends on people who speak.

    Potential opportunity: Measuring by each customer's return rhythm instead of by complaints.
