Article: What Would Alan Cooper Do?
In this article, Naysawn Naderi makes a summary of About Face 3, Alan Cooper’s book, noting some key takeaway points. The User Interface plays an important role in an application, be it a desktop one, a web application or a mobile one, and the guidelines contained by the article help creating better interfaces.
The key points contained by Naysawn’s article are:
Design for Intermediates Users – Most products are developed for either beginners or advanced users, but they should target the intermediate ones since they represent 80% of the target users.
Use Tools that Help Beginners to Become Intermediates – The interface should provide different helps for beginners than intermediates.
Less is More – Provide as little graphical controls as possible.
Design for the Probable, Provide for the Possible – Make most probably tasks to be most accessible (1 click), but also have options for possible tasks.
Eliminate Errors or Confirmation Dialogs – Avoid error and confirmation dialogs as much as possible.
Eliminate Errors or Confirmation Dialogs
A good minimalist approach will be to have confirmation dialogs only for "destructive" and irreversible user actions (ie: disk formatting, overwriting existing files, etc.) In all other case, a status bar is just fine to display success or error messages without distracting the user.
