Lately we have been putting together a list of resources to help people find more information about web usability. Below is a partial list of what we have so far. As a note just because we have it listed below doesn't mean that it will provide a silver bullet to your particular need or problem, but inside provide you with more information so that you can make a more informed decision. A second note would be that this is just the start of a list that will continue to grow (and hopeful I will remember to post the updates)

Designing the User Experience
Delivering Usability: The Ultimate Collaboration
Website Usability represents the cornerstone of any online destination. To achieve excellent usability standards, there must be a coherent collaboration between all those involved in the website project, from conception to design to delivery. From marketing to graphic design, from the human factors and the psychology of internet usage, everything must combine to create the ultimate user experience. Nothing should be compromised in this pursuit of functionality, be it branding, content, or any other facet of the website.
Having a concept, designing the website, writing the copy; with every aspect of creating a website, it is imperative to ensure that usability needs remain at the forefront of your thinking. Simply put, when you construct a website, delivering superior usability standards is, or at least should be, the ultimate goal.
Real Research, Real Results
Knowing and appreciating the user experience is crucial to the successful delivery of usability. Harnessing the increasing physiological markers which define how people use the internet can give your website a cutting edge in usability. If you employ the correct user-testing protocol and conduct such tests in a well established format, the results will invariably provide indispensable data. Knowing the audience and understanding your potential market is an excellent way of gaining the information you need to deliver what users look for.
User Profiles
Though it is important to conduct tests well and ensure that the results are correlated correctly, it is equally important to profile the users. Demographics, technology experience, expertise on the subject matter, attitudes, motivations and frequency of usage are all essential guides to whether a person is appropriate for the testing process. Also of critical importance is to ensure that the users are testing in 'real-world' scenarios rather than simulated tests which are unlikely to occur in practice.
Navigation, Navigation, Navigation
When it comes to navigation, the big picture comes sharply into focus. Always consider where the user starts, how they get from one page to the next, how they get back to where they came from and all variations of this theme. Create a flow chart or similar visual representation of the complete navigational model of the site. This enables a clear, unobstructed navigation map which you can implement to design floorless navigation across the website.
The overall comfort of the online visitor is massively enhanced on a website which does not disorient them or make them feel as if there is now way back.
Conceptual Models
When a user browses a website, an overall mental image develops with regards to how the system works. Usability is intrinsically linked to design, thus demanding a conceptual website model which creates an accurate mental model for the user. It is also crucial to ensure that the conceptual design is related to the way any given person thinks about their work, i.e. a logical, easy to follow concept.
From page to page, the design of a website should form a quality model which translates into a seamless user experience, with a clear emphasis on usability.
User Centered Design
Developing goals, user profiles and task analysis should all be user centered. From the birth of any project, the goals of the website should be firmly rooted in the potential and likely goals of the eventual user. Throughout the entire design, building and creative process, user input is absolutely indispensable in the quest to ensure a great user experience and high level of customer satisfaction on your website.
As well as including the user from the very start, it is important to keep the user experience at the epicenter of the process. Ongoing concern for the user experience must never be overlooked.
Heuristic Evaluation
When assessing web usability, the heuristic evaluation is of pivotal importance. Essentially, this evaluation is an assessment of the design based on well established and recognized design principles. When a qualified usability professional conducts a heuristic evaluation of a website, one of the main aims is to try and uncover potential user problems. Any such problems related to aspects of the website design are usually additional issues not uncovered by previous usability testing. Being thorough pays dividends and usability success cannot be achieved by cutting corners.
Ultimate Usability
Achieving truly great usability is not an overnight story. As on ongoing process, the constant chase towards the best user experience is an evolutionary and unending quest. If the notion that the user experience is the importance important component of any and every website remains front and centre, usability will be easier to achieve, deliver and maintain.
There are many reasons why people abandon websites, fail to complete online purchase, look elsewhere for other companies online or just plain avoid your site after one unsuccessful visit. Ultimately, online users have a low patience threshold when it comes to online experience. Of the many reasons people give up on websites, simple things such as bad navigation, broken links, inconsistent icons and hard to understand site maps can be eradicated with a more usability centered approach to the site.
The online experience changes daily and the standards people now expect on your website are becoming higher. Time is often of the essence for the user and any usability issues which delay, stunt or arrest the progress of whatever it is trying to be achieved, often means you lose them for good. Repeat business can be crucial, especially to websites that base much of their business on ecommerce. Good usability can, simply put, be the difference between alienating a first time visitor and creating a loyal, repeat customer for your business.
Usability is not a luxury, it is a necessity.
