I’ve been doing allot review/reading lately, visiting dog-eared old books, and looking through my Evernote bucket for tidbits of user experience wisdom. I came across this list of 34 maxims (this format was at one time particularly popular) created by Arnold Lund. I find lists like this particularly useful for mapping to past learning and experience. Created in 1997, it’s still as relevant today as it was then, and it serves as a useful reminder and a great guide for future work.

1. Know thy user, and YOU are not thy user.
2. Things that look the same should act the same.
3. Everyone makes mistakes, so every mistake should be fixable.
4. The information for the decision needs to be there when the decision is needed.
5. Error messages should actually mean something to the user, and tell the user how to fix the problem.
6. Every action should have a reaction.
7. Don’t overload the user’s buffers.
8. Consistency, consistency, consistency.
9. Minimize the need for a mighty memory.
10. Keep it simple.
11. The more you do something, the easier it should be to do.
12. The user should always know what is happening.
13. The user should control the system. The system shouldn’t control the user. The user is the boss, and the system should show it.
14. The idea is to empower the user, not speed up the system.
15. Eliminate unnecessary decisions, and illuminate the rest.
16. If I made an error, let me know about it before I get into REAL trouble.
17. The best journey is the one with the fewest steps. Shorten the distance between the user and their goal.
18. The user should be able to do what the user wants to do.
19. Things that look different should act different.
20. You should always know how to find out what to do next.
21. Don’t let people accidentally shoot themselves.
22. Even experts are novices at some point. Provide help.
23. Design for regular people and the real world.
24. Keep it neat. Keep it organized.
25. Provide a way to bail out and start over.
26. The fault is not in thyself, but in thy system.
27. If it is not needed, it’s not needed.
28. Colour is information.
29. Everything in its place, and a place for everything.
30. The user should be in a good mood when done.
31. If I made an error, at least let me finish my thought before I32. have to fix it.
32. Cute is not a good adject33. ive for systems.
33. Let people shape the system to themselves, and paint it with their 34. own personality.
34. To know the system is to love it.
