Heuristic Analysis is useful to test rough
designs. Experts are better able to

design phases.
If designs are tested with experts first,
later user testing can focus on less obvious
issues, which can arise only from user
testing.
One-to-one user testing Test users matching the target
demographic carry out key usage
scenarios/tasks. This is a thorough
technique, uncovering bugs that emerge

Field Test Usability testing by actual users in the

What Role does Usability Play at SpireMedia?
SpireMedia believes in user-centered design. For many interactive design agencies,
usability is an afterthought. At SpireMedia, it permeates our approach, from
information architecture, to design, to engineering.
SpireMedia designs and builds applications for real use by real users. This creates
web sites that work -- that strengthen our clients’ brands by creating positive
interactions -- information and products found easily, experiences that satisfy users
by recognizing and paving the way to their objectives.
Why is Usability a Key Part of the SpireMedia Process?
More than any other design factor, usability determines the success or failure of
any serious web initiative. By making usability the focal point of our design
approach, we ensure that our clients receive maximum return on their investment.
SpireMedia provides clients with web sites that strengthen brands, set the stage for
transactions and increase efficiency. Usable design creates a perception of value
and an expectation of future positive interactions.

- 2. [email protected] What is Usability? Usability is what makes a web site work. More specifically, it’s the degree to which a web site or software program helps users do what they want to do. Whether they intend to make a specific purchase, find a specific piece of information or simply browse, usability is what helps users fulfill their objectives efficiently. There are many ways to measure the usability of a web site, including: • How quickly can a user find a specific item or piece of information? • How many steps does it take to achieve a goal? • Do users become lost, disoriented or overwhelmed? • Does the design help users reach their goals, or does it get in the way? Though usability is critical to the success of any interactive design, it’s consistently the most frequently overlooked and undervalued aspect of design, possibly because usability problems are frequently invisible to the untrained eye. Why is Usability Important? A company’s brand is the sum of its customer interactions. This includes: • Store visits • Receiving media-based marketing messages • Support and telemarketing calls • Product use • Web site visits Many companies spend millions of dollars on marketing media, attempting to “communicate” their brand. Customers increasingly base their brand perceptions on their interactions with a company, and how those interactions live up to the marketing promises the company makes. In short, a multimillion-dollar ad campaign can be instantly sabotaged by a dinner-time telemarketing call or an dissatisfying web site visit. Poor usability carries damaging consequences, regardless of the type of application being designed: Type of Application Consequences of poor usability Informational web site Unsatisfactory interaction and subsequent damage to the brand Intranet or software Reduced productivity, creating a steady flow of application lost resources E-commerce web site Aborted transactions, abandoned shopping carts, low conversion rates (browse-to-buy ratios) How do You Make a Web Site Usable? © SpireMedia 2003 Page 2 Usability White Paper
- 3. Designing a usable web site begins with learning about the user. Some user needs and characteristics can be inferred and uncovered by experts. However, to maximize usability requires observing real users using the application in the intended usage environment. There is much ground between these two approaches. And somewhere within that continuum is the best solution for every application. The design must be grounded in a solid understanding of the intended users and their objectives in using the site. This is called “design for use,” or “user-centered design.” Every design decision, from functionality to visual design, should be evaluated in terms of what solution best serves the users’ ability to fulfill their objectives. You Don't Really Need Real Users, Do You? Many companies choose not to conduct user testing, or truly user-centered design based on a number of well-worn objections: "Believe me, we know our users better than anyone, maybe even better than they know themselves. Our sales people are in constant contact with our customers. They're totally in tune with their needs. In fact, some of our current staff came directly from client organizations." Unfortunately, none of these beliefs change the fact that we all hold assumptions about our customers and users. In fact, customers and users are constantly evolving and we never really have a full understanding of what they need and how they'll respond to a new product or touch-point until we bring them in and do the research. Usability Techniques Today’s usability practitioner has a wealth of tools and techniques to draw from, all appropriate under certain circumstances. Usability Technique Description/Outcome Focus Group Focus Groups assemble members of the target audience for an open discussion of functionality. Focus groups can effectively test and develop concepts to inform design. Ethnographic Research Observing users conducting tasks in their native environment. This reveals work habits, task flows and environmental factors that affect design. Ethnographic Research is essential when designing applications to be used by specific users in a specific environment. © SpireMedia 2003 Page 3 Usability White Paper
