You have a party test your product idea. What do you ask for as the outcome?
The report ends with a plain recommendation: go ahead, adjust or stop. It is yours, even if you carry on with another party.
-
A colleague says: 'An MVP is a cheap trial version; we build it properly later.' What is true?
An MVP is the real product in its first form: it must work and be safe for real customers. The difference is in what is left out, not in how carefully it is built.
-
Your first prototype works on the desk. Where do you test it next?
A prototype that works on the desk proves little. The real test is at the machine that vibrates, in the cold store or in the van.
-
The design of your circuit board is finished. In what form do you get it?
You get schematic, layout, parts list and production files as source files in a common program. Another designer or your own people can carry on with them.
-
Which task fits a small model on a device?
A language model like the one in a chatbot does not fit on a microcontroller. Questions on the floor are small and sharp, and small specialised models handle those.
-
A colleague says: 'EMC is for the test lab; we will see there.' What is true?
Where the ground planes lie and whether the supply has a filter decide EMC; the lab only measures it. A pre-measurement on the prototype shows whether you are ready for the lab.
-
Mid-production, the supplier reports a long lead time for a chip. What helps you then?
Find alternatives beforehand, not once the lead time is reported. Ideally they fit without changing the board.
-
A customer complains about unit 137 of your batch. How do you find out what happened?
Every device gets its firmware, a serial number and a test before it goes in a box, and the measured values are kept. So you know what was measured at the factory.
