Spreadsheets that don't break when someone else opens them.
Most spreadsheet advice teaches tricks. Column A teaches structure: the small set of rules that decide whether a file still works six months from now, in someone else's hands.

The dangerous errors are the ones that don't turn red.
A file works perfectly for the person who built it. Then it's shared, inherited, edited by four people, and six months later it produces a number nobody can explain and nobody can check.
Silent failure
No error message ever appeared. The formula still returns a number, just not the right one.
It depends on one person
When only one person knows how a file works, everyone else has to wait for them. Holidays, handovers and someone new joining the team all become the same problem.
Structure, not tricks
A clever trick solves today's problem. How a file is built decides whether it still works after it changes hands.
