A showstopper usability bug can also be one that is likely to cause frequent data integrity errors. There is no workaround to these problems. A key feature needed by many customers is not in the system.EXAMPLES: An obvious competitive feature is missing, or the customer expects something reasonable, but the feature isnt there. Critical data is lost often because users are expected to “know” to save their data or do something that is complex to preserve the data. For example, if the application allows users to exit without prompting them to save their changes or asking if they want to save a session. The usability problem is likely to result in an error that will cost the customer a large amount of wasted time or money (for example, a problem that would delay the recovery of a transaction database) The usability problem is likely to lead to a significant safety or health risk. Legal issues like missing copyright notices or improper use of another companys trademarks2 HighA serious condition that impairs the operation, or continued operation, of one or more product functions and cannot be easily circumvented or avoided. The software does not prevent the user from making a serious mistake. The usability problem is frequent, persistent, and affects many users. There is a serious violation of standards.EXAMPLES: There is no keyboard access method for a feature. The way to work around the problem is very hard to explain or hard to remember. The problem is likely to result in many support calls. Missing or undocumented parameters, menu commands, or other important information in the interface or documentation. Serious violations of corporate user interface design standards Offensive, inappropriate, or non-standard icons for standard functions Missing feedback for critical operations3 MediumA non-critical, limited problem (no data lost or system failure). It does not hinder operation and can be temporarily cicumvented or avoided. The problem causes users moderate confusion or irritation.EXAMPLES: Keyboard access is possible, but not easy. Tab order does not follow the user interface guidelines A common menu item or toolbar button does not do what is normally expected. Incorrect or no error messages (this could be High or even a showstopper in some cases if a bad error message results in lost data) Incorrect data are generated (this could be a high or a showstopper bug if it causes the user to make a bad decision that has significant implications for the user or company) Noticeable performance inefficiences (this can be a high if the performance is bad enough) Use of the wrong control in the interface (the wrong control causes some moderate performance degradation Missing or incorrect titles or units Unneeded clutter that does not have a major impact on user performance4 LowNon-critical problems or general questions about the product. There are minor inconsistencies that cause hesitation or small aesthetic issues like labels and fields that are not aligned properly.EXAMPLES Typos (this could be a higher priority if they are in key places like menus or splash screens) A menu item does not use the recommended access character Small cosmetic problems
