Copperfield Kitchens, a small kitchen-fitting business, broke its booking system by 'quickly changing a setting' — the next morning customers could not book. The scene shows a change as one step from a working before to an after, checked straight away; when the after is broken, a bold undo arrow puts it back to the working state. Beside it, the before-you-change-it checklist: know what it touches, have a way back, one thing at a time, check it worked, and tell people and note it — and never wave a 'small' change through.

The Undo — Making Changes Without Breaking Things

Most things break right after a change — so change carefully and reversibly. Know what a change touches, have a way to put it back, change one thing at a time, check it worked, and tell people. Never rush a change, and never wave a small one through.

What you'll learn

  • Understand that changes are when things break, and know what a change touches before you make it.
  • Have a way to undo a change before you make it, and change one thing at a time so a breakage points to its cause.
  • Check a change worked and broke nothing else, tell the people it affects, and keep a simple note of what changed.
  • Avoid rushing a change under pressure and waving a small one through — giving every change proportionate care.
