A commitment to usability in user interface design and development offers enormous benefits, including greater user productivity, more competitive products, lower support costs, and a more efficient development process. But what does it mean to be committed to usability? Inside, a twenty-year expert answers this question in full, presenting the techniques of Usability Engineering as a series of product lifecycle tasks that result directly in easier-to-learn, easier-to-use software.You'll learn to perform a complete requirements analysis and then incorporate the resulting goals and constraints in a highly structured, iterative design and development process. This process doesn't end with installation but instead begins anew with the collection of user feedback that will guide further development. Also covered are organizational issues related to the implementation of Usability Engineering, including cost justification, project planning, and organizational structures.
