User experience (UX) involves a person's behaviors, attitudes, and emotions about using a particular product, [[system]] or service. User experience includes the practical, experiential, affective, meaningful and valuable aspects of human-computer interaction and product ownership. Additionally, it includes a person’s perceptions of system aspects such as utility, ease of use and efficiency. User experience may be considered subjective in nature to the degree that it is about individual perception and thought with respect to the system. User experience is dynamic as it is constantly modified over time due to changing usage circumstances and changes to individual systems as well as the wider usage context in which they can be found. | User experience (UX) involves a person's behaviors, attitudes, and emotions about using a particular product, [[system]] or service.

 | This page in a nutshell: Usability aims to make it easier for a reader to navigate content. |
|
Web usability is an approach to make web sites easy to use for an end-user, without the requirement that any specialized training be undertaken. The user should be able to intuitively relate the actions he needs to perform on the web page, with other interactions he sees in the general domain of life e.g. press of a button leads to some action. The broad goal of usability can be:
- Present the information to the user in a clear and concise way.
- To give the correct choices to the users, in a very obvious way.
- To remove any ambiguity regarding the consequences of an action e.g. clicking on delete/remove/purchase.
- Put the most important thing in the right place on a web page or a web application.
What is user-centered design?
User-centered design (UCD) is an approach to building products that incorporates end user feedback throughout the planning, design, and development of the product. This approach considers both your program objectives and your end user's needs and preferences, and ensures that the final product is both useable and useful to your target audiences.
Why should I care about usability?
When users can successfully accomplish their tasks on your site, you will accomplish your program goals. Incorporating usability techniques into your design process makes smart business sense because:
- It helps you align your end users’ goals with your program goals.
- It helps you figure out what content you really need on your site – and what content you don’t. Getting rid of unnecessary content reduces maintenance costs.
- Unforeseen or unmet user requirements results in increased maintenance costs.
- Visitors who can’t find information make uninformed decisions.
- Visitors who can’t complete tasks on your sites contact you instead.
- Customers who have bad experiences on websites view the sponsoring organizations as untrustworthy.

User experience (UX) involves a person's behaviors, attitudes, and emotions about using a particular product, system or service. User experience includes the practical, experiential, affective, meaningful and valuable aspects of human-computer interaction and product ownership. Additionally, it includes a person’s perceptions of system aspects such as utility, ease of use and efficiency. User experience may be considered subjective in nature to the degree that it is about individual perception and thought with respect to the system. User experience is dynamic as it is constantly modified over time due to changing usage circumstances and changes to individual systems as well as the wider usage context in which they can be found.
How do I get started?
The first step in any usability project is to do some user research – get to know who is currently coming to your site and what they are trying to accomplish when they come. User research can include conducting surveys, setting interviews, reviewing statistics and/or going over webmaster feedback – the methods you choose depends on your time and budget.
The next steps depend on your research questions:
- Is your target audience actually coming to your site? If not, consider a marketing campaign.
- How well can users accomplish their goals using your current site? Find out with a usability test.
- How do I organize my site content so it’s intuitive for my users? Try card sorting or tree testing.
- Will my new layout/design work for my users? Consider wireframe or prototype testing.
Remember, usability methods are scalable to your time frame and budget – your site visitors will thank you for any efforts you can make. And your program will thank you too when your website directly contributes to an increase in satisfaction with the program while decreasing maintenance costs.

Usability testing refers to evaluating a product or service by testing it with representative users. Typically, during a test, participants will try to complete typical tasks while observers watch, listen and takes notes. The goal is to identify any usability problems, collect qualitative and quantitative data and determine the participant's satisfaction with the product.
To run an effective usability test, you need to develop a solid test plan, recruit participants , and then analyze and report your findings. Please also see the resources at Web_usability#Usability_testing_expert.
Screen sharing tools (WebEx, Adobe Connect, gotowebinar, gotomeeting, google hangouts, etc.) are often to see the test participants screen, share the test observation with remote folks, and record the session.
Benefits
Usability testing lets the design and development teams identify problems before they are coded. The earlier issues are identified and fixed, the less expensive the fixes will be in terms of both staff time and possible impact to the schedule. During a usability test, you will:
- Learn if participants are able to complete specified tasks successfully and
- Identify how long it takes to complete specified tasks
- Find out how satisfied participants are with your Web site or other product
- Identify changes required to improve user performance and satisfaction
- And analyze the performance to see if it meets your usability objectives
Possible tools

Morae
Morae gives you the ability to set up, record, observe, and analyze usability studies, focus groups, field research, and product testing. You and others can watch the study or interaction remotely, take notes, and then analyze results to instantly share your insights with others.
