You don't need to be convinced. You know that usability is key to the success of any interactive system-from commercial software
to B2B Web sites to handheld devices. But you need skills to make usability part of your product development equation. How will you assess
your users' needs and preferences? How will you design effective solutions that are grounded in users' current practices? How will you
evaluate and refine these designs to ensure a quality product?
Usability Engineering: Scenario-Based Development of Human-Computer
Interaction is a radical departure from traditional books that emphasize theory and address experts. This book focuses on the realities
of product development, showing how user interaction scenarios can make usability practices an integral part of interactive system development.
As you'll learn, usability engineering is not the application of inflexible rules; it's a process of analysis, prototyping, and problem
solving in which you evaluate tradeoffs, make reasoned decisions, and maximize the overall value of your product.
Audience
Novice HCI practitioners, usability engineers, software developers, web page designers and developers, and undergraduate or graduate level
computer science and engineering professors, instructors, and students.
