Many people in the usability community regard Steve Krug’s book Don’t Make Me Think: A Common Sense Approach to Web Usability, 2nd Edition as the laypersons usability bible. This book explains briefly and concisely everything one needs to know about getting started with web usability. For more advanced users, it’s a great refresher course.
UX Booth has been open for more than half a year now, and when we started I was always regarded as the layperson of the group. After getting all serious about usability, I’ve re-read Steve Krug’s Don’t Make Me Think and pulled out what I consider to be the most insightful and best thoughts in this book.
We highly recommend picking up a copy if you get a chance, but here are some things to think about in the meantime. Some are simple and straightforward but worth remembering, some are just phrased beautifully, and some will make you think.
Usability means making sure something works well, and that a person of average ability or experience can use it for its intended purpose without getting hopelessly frustrated.
As far as humanly possible, when I look at a web page it should be self-evident. Obvious. Self-explanatory.
As a rule, people don’t like to puzzle over how to do things. If people who build a site don’t care enough to make things obvious it can erode confidence in the site and its publishers.
Much of our web use is motivated by the desire to save time. As a result, web users tend to act like sharks. They have to keep moving or they’ll die.
There’s not much of a penalty for guessing wrong. Unlike firefighting, the penalty for guessing wrong on a website is just a click or two of the back button. The back button is the most-used feature of web browsers.
If we find something that works, we stick to it. Once we find something that works — no matter how badly — we tend not to look for a better way. We’ll use a better way if we stumble across one, but we seldom look for one.
Happy talk is like small talk – content free, basically just a way to be sociable. But most Web users don’t have time for small talk; they want to get right to the beef. You can – and should – eliminate as much happy talk as possible.
Some people (search-dominant users), will almost always look for a search box as they enter a site. These may be the same people who look for the nearest clerk as soon as they enter a store.
When we return to something on a Web site, instead of replying on a physical sense of where it is, we have to remember where it is in the conceptual hierarchy and retrace our steps.
Having a home button in sight at all times offers reassurance that no matter how lost I may get, I can always start over, like pressing a Reset button or using a “Get out of Jail free” card.
