7 important questions on UCD principles - THOU MUST KEEP IT SIMPLE

What kind of users are the experts?

Experts design products for themselves which causes difficulties for people who are not experts. Experts represent the smallest population of users even though they tend to be the most vocal and capable problem-solvers.

What kind of users are the willing adopters?

The willing or early adopter is someone who likes trying new things or is willing to take risks and explore the potential of what a product might do for them even if it doesn’t work efficiently yet is expensive to operate or requires regular repair.

What kind of user are the mainstreamers?

Mainstreamers, on the other hand, just need the thing to work and to save them some time and energy. They have little patience for troubleshooting.

What is meant with prioritizing in UCD?

Discover the features that do or don’t contribute to primary tasks/purposes. From there, define the next most important features for conducting typical tasks and then the features that do not need to be there, no matter how “neat” they are.

What is meant with "removing" in UCD?

Another critical step is to remove unnecessary features. In some cases, features are superfluous, meaning the user doesn’t need or want them. In other cases, the features shouldn’t be included in the first place and belong in or should be used with a more appropriate tool or system. One good rule of thumb is to remove functions only the engineer/designer would know how to use.

What is meant with relocating in UCD?

Another great way to simplify an interface, tool, or use environment is to move features in a way that puts the most heavily used features in the most immediately accessible place.

What is meant witgh "hide" in UCD?

One of the best ways to help users focus on a task without being overloaded by other features is to temporarily hide other features or relocate these features in menus that the user can explore if they’re interested.
