Ship it to one other person

Build-along · ~45 min at your own keyboard

A tool is not shipped until someone else uses it. You cannot see your own tool the way a new user does. You know where every button is. So give it to one other person and say nothing. Watch what they do. Do not help. Write down the first place they stop or click the wrong thing. That is your most valuable finding. Fix that one thing. Then you have shipped. This lesson is reviewed in class, so keep your notes honest. A good result is one with a real trip and a real fix. A report that says 'it was perfect' has not been tested well.

The Tuesday class (peer + instructor): Bring the link and the spec. One classmate uses it cold while you watch; the reviewer checks it against the spec's done line.

Checkpoints

▸You should now see your tool open at a link on your phone, and not showing private data when you are signed out.
▸You should now see written notes of what one other person did, including at least one place they stopped or went wrong.
▸You should now see one fix, made and checked, for the first thing they tripped on.

The three ways this goes wrong

You helped the person halfway through. — Your notes are now about your help, not the tool. Get a second person, say only the one-line task, and stay quiet. The first trip is the finding.
The person used it with no trouble at all. — Ask a harder task: 'Add a job, mark one done, then find yesterday's jobs.' Or pick a second person who is less used to apps. A clean first test is rare.
The link shows private data, or works for anyone who has it. — Take the tool offline now. Add a sign-in or limit access to named people. Check it again in a private window before you share it.
