The order to work through when you assess a consumer product from scratch

Start with the dripper itself, not with a rating. Write down its weight when full, the diameter of its base ring, the surface it sits on, and whether it needs a separate stand. A dripper that balances on a narrow mug behaves very differently from one that sits in a wide carafe, and that difference decides most of the later reasoning.

Next, describe the pour in full. The seller should picture a morning routine: a kettle in one hand, a phone in view, a sink that may be wet, and a dripper lifted while still hot. If the assessment only describes a careful laboratory pour, it will miss the ordinary rush that makes a spill plausible.

After the description, list every person who touches the dripper and every stage from unpacking to washing. The buyer pours, a partner may rinse it, and a child may reach for it while it cools on a counter. Each stage adds a chance for a slip, a knock, or a misjudged grip on a hot rim.

Then turn each stage into a sequence. For the sink stage, the sequence might run: wet hands, a narrow mug, a dripper lifted by its rim, a tilt, and hot liquid running toward a wrist. Writing the sequence out forces the assessor to notice the exact moment where a wider base, a handle, or a clearer instruction would interrupt it.

Illustration: a seller imagines 60 mornings of use and supposes that on 30 of them, in round illustration terms, the dripper is lifted while the mug below is still being steadied with the other hand. Those numbers are invented, not observed. Their purpose is to show why the sequence matters: if lifting while steadying is common, the assessment cannot treat it as a rare accident.

The seller then asks what the numbers would need to be before the judgement changed. If even a far smaller share of mornings involved that grip, would the spill sequence still deserve a design change or a warning. That question, answered in writing, is more useful than the invented figures themselves.

Only after the sequences are written should the assessor judge them. For each sequence, note how serious the harm could be, how readily it could occur, and what evidence supports those views. A scald from a full dripper deserves careful attention, but the judgement should also explain why it is placed where it is, rather than leaning on a single word like high or low.

• Record the harm, the sequence, and the evidence beside each judgement.
• Note any sequence where the evidence is thin and more handling is needed.
• Decide whether to change the design, change the instructions, or accept the risk with reasons.
• Set a trigger for revisiting the judgement, such as a shape change or a complaint.

A frequent error is to start with the answer. A seller who decides on the first day that the dripper is safe will tend to write descriptions that support that answer and sequences that end happily. The order in this guide exists to prevent that drift: description first, sequences second, judgement last, with the reasoning visible at each step.

Another error is to assess the dripper in isolation. The dripper is always used with a mug, a kettle, and a sink, and a change to any of those partners changes the sequence. An assessment that never mentions the mug it sits on is incomplete, however neat its scoring table looks.

Close the assessment by reading it as a stranger would. Can that reader tell what the dripper is, how it is used, what could go wrong, and why the final decisions were made. If any of those questions needs a guess, add the missing sentence before filing.

Finally, hand the finished sheet to the person who writes the listing. The listing should reflect the same cautions as the assessment, in the same plain language, so a buyer learns about the hot rim and the narrow base before buying, not after the first spill.
