| Design to Reduce Memory Work | ||
|---|---|---|
| 1. Support navigation memory | For tasks requiring frequent navigation, consider a "task panel" with continuously visible options (no memory required) |
 |
| 2. Make sequence clear | Avoid arbitrary sequencing like alphabetic (unless it's names or the dictionary). User can't remember which word to look for. Task order is better (see next). |
 |
| 3. Group options and tasks | The eye and memory handle about 5 lines at a time. Use blank space to group by concept. The "portfolio" buttons would make a good separate group. |
 |
| 4. Avoid need for long-term memory (and consequent training) |
Avoid arbitrary codes |  |
| Use meaningful indicators |  |
|
| 5. Avoid interrupting short-term memory | Avoid long instructions like this. (You forget the instruction!) Consider using button labels as brief instructions (e.g., "First-time User Registration" placed at the top) Build tasks to be self-evident. |

Design to Reduce Physical Work |
||
| 1. Reduce scrolling requirements | Avoid scroll requirements unless its obvious. (This page isn't obvious) Make first page self-contained, if possible |
 |
| Consider the extra work caused by icons in your menu. Is the work worth it? |  |
|
| 2. Avoid "window thrashing" | Pop-up windows easily get lost by users who click on the window behind the popup |  |
| 3. Minimize typing complexity | Avoid lugubrious URLs |  |
| 4. Offer large targets for mouse clicks | Avoid tiny buttons. Large buttons speeds mouse movement. Put labels on the buttons |  |
| 5. Question "splash graphics" | A gratuitous graphic page merely means extra clicks (and waiting) |  |
