Review the guidelines for attaining usability of forms and reports in Table 10-9. Consider an online form you might use to register a guest at a hotel. For each usability factor, list two examples of how this form could be designed to achieve that dimension of usability. Use examples other than those mentioned in Table 10-9.

Table 10-9

Usability Factor Guidelines for Achievement of Usability Consistent use of terminology, abbreviations, formatting, titles, and navigation within and across outputs. Consistent response time each time a function is performed. Formatting should be designed with an understanding of the task being performed and the intended user. Text and data should be aligned and sorted for efficient navigation and entry. Entry of data should be avoided where possible (e.g., computing rather than entering totals). Outputs should be selfexplanatory and not require users to remember information from prior outputs in order to complete tasks. Labels should be extensively used, and all scales and units of measure should be clearly indicated. Information format should be consistent between entry and display. Format should distinguish each piece of data and highlight, not bury, important data. Special symbols, such as decimal places, dollar signs, and = signs, should be used as appropriate. Information should be viewed and retrieved in a manner most convenient to the user. For example, users should be given options for the sequence in which to enter or view data and for use of shortcut keystrokes, and the system should remember where the user stopped during the last use of the system.
