The school app lab: Team lead

A school library is testing a borrowing app with invented records. You play the team lead and work through 9 short levels, about 14 minutes in all. Where you start: A useful software rule says who can do what, including what happens when information is missing. The work connects to careers such as data analyst and software engineer. It is free, and your reflection stays private.

What does a team lead do in this activity?

A school library is testing a borrowing app with invented records.

A library rule, a missed case and a careful release.
