Web Application Type: Open
Open Online applications that are easily accessible to
anyone who opens an account (either for free or by paying a fee)

Web Application Type: Open
Web Application Type: Closed
Closed/line-of-business Usually not accessible outside the company that
uses it, and they can be considered "offline" applications (though many systems expose their functionality to business partners via either services or specialized interfaces)
Usually run on the company's local network and are available only to employees

Research Techniques for Knowing Your Users
User Interviews Guided conversations with existing or potential
users to help you understand their preferences and attitude
Contextual Inquiry Combining direct user observation with an
interview that takes place in the users environment in order to better understand their work environment, the problems they are trying to solve and other related preferences

Surveys A clear set of questions distributed to a wider
audience in order to gather results that can help validate existing data and personas
Card sorting A grouping task for individuals or small groups used
to establish common patterns and identify areas of confusion

Usability testing The process of performing a series of specific tests
on a site or a product to reveal potential usability problems and identify solutions to address them

Task Analysis The process of learning about ordinary users by
observing them in action to understand in detail how they perform their tasks and achieve their intended goals
Help identify the tasks that your website and applications must support and can also help you refine or re-define your site's navigation or search by determining the appropriate content scope

Helps you understand: What your users' goals are; what they are trying to
achieve What users actually do to achieve those goals What experiences (personal, social, and cultural) users
bring to the tasks

Design Principle: Usability
Facts about human vision and seeing We have sharp vision in the center of our focus that
is good at paying attention and identifying detail We have poor peripheral vision that can identify
movement and contrast, but not identify detail

Design Principle: Usability
Facts about human vision and seeing Shadows help us perceive information in three
dimensions – light from above and shadow below makes things pop out of the page
Sudden movement, changes in contrast and the appearance of images can attract visual attention

Design Principle: Usability
Checklist for choosing components Is there enough contrast and spacing for a user to
really see the component? Do changes happen right where the user is
looking? If changes happen outside the field of vision, is
there something that will attract visual attention (movement or color) so they see the change? And does the change persist long enough to be spotted?

Attribute of an item that communicates what can be done with it When effective, users should be able to figure out
what to do with an item just by looking at it Shadows and highlights can make buttons pop,

Feedback and error recovery Users should be informed about (potential) errors
and how they can affect their work Also contains actions which users can perform in
order to recover from the error Some mistakes are irreversible so it is important to
suggest solutions to help remedy problems

Design Principle: Responsiveness - Fast
The interface, if not the software behind it, should work fast
Seeing things load quickly, or at the very least, an interface that loads quickly (even if the content is yet to catch up) improves the user experience

actions

Design Principle: Responsiveness - Errors
Choosing the right components is a very big factor in error management
A combo box (combination of single-select list and text entry box) reduces the error to a much greater extent than just a text entry field
Giving the user an initial set of options, simple data entry and formatting errors can be avoided
Date pickers reduce the margin of error compared to date text entry fields
Auto-complete helps people select from long lists

Confirmation fields When dealing with data that is important to the

This way users can be certain that they provided correct information
e.g. passwords, email addresses

Rules of Thumb in Web Form Validation Design
Never omit server-side validation Do not provide confusing validation feedback. It
should clearly communicate the errors and ways to fix them.
Do not let users think about what information is required, always clearly mark required fields
Never provide validation feedback on a single page or in a popup alert

Rules of Thumb in Web Form Validation Design
Do not use dynamic effects as a compensation for a badly designed form. Fancy effects would not hide a poorly designed web form.
If you use Captcha, do not forget to provide audio support and enable users to "reload" the Captcha
Do not forget to inform users when the form was completed successfully. It is as important as a good validation feedback.
