Achievement Symbols (GT#2)
Badges, ranks, certificates and similar symbols that mark a real accomplishment. They carry weight only when the feat behind them was hard for the audience in question; symbols for trivial actions insult adults and cheapen every other badge.
Plain label: earned badgesAlso known as: Achievement Symbols, badges, certificates
How it works
A symbol reminds people of an accomplishment; it is not the accomplishment, so the motivation comes from the challenge it stands for (CD2). Chou describes keeping a printed seller certificate for years because the milestone was real. Match the symbol to the audience, since what thrills a child insults a professional. Inflation, such as badges for opening the app, drains meaning from the whole set.
How to build it
- Web
- Badges for skill feats ('first automation with three conditions'), shown as silhouettes until earned, with a few hidden ones.
- B2B
- A certification that requires a graded project, downloadable and signed by a named person.
- Mobile
- Milestones tied to real effort, such as 30 workouts, rather than app opens.
What can go wrong
- Participation badges that reward nothing.
- So many badges that none means anything.
- Symbols pitched at the wrong audience, such as childish badges for professionals.
Pairs well with
- Display earned symbols on a profile (GT#64 Trophy Shelves).
- Attach a usable perk so the symbol is not display-only (GT#31 Boosters).
