Usability engineering {usability engineering} solves usability problems. Work flows have bottlenecks, where processes slow and inventory piles up. Usability engineering concentrates resources on improving bottlenecks, typically user interface (UI) design of tools and menus. Tasks must be relevant to goals and relatively easy to perform and understand. Work items are analyzed for relevance, speed and ease of search and transfer, ease of understanding, and possibilities of mistakes. Users perform relevant tasks with more attention and good will. Understanding is better if all terms defined, steps read easily, necessary preconditions noted, branches noted, procedure accurate and tested, and steps presented one at a time. Speed is better if fewer steps, less data, fewer branches, fewer decisions, and fewer clicks. Usability engineering typically reallocates work items from human objects to inanimate objects to reduce information burdens on users. Systems can guide users to information by directed search, using context-sensitive help and dialog-box help. Systems display only the most needed information. Distinctive locators include pop-up help, labels, and grouped menu items and interface objects. Wizards and coaches present a defined way of working.
