Census Bureau

User Group 1: Administrative applications designers and developers.

Importance: 2 - somewhat important. These applications designers and developers are primarily concerned with the development of PC-based applications, although some may be accessed on the Census Bureau's Intranet. The frames accessibility issue of this task is specific to the Web (Internet and Intranet). Therefore it may be important in some situations, but in most cases frames do not effect the applications being developed by this user group.

Task Performance: All members of this user group should be able to complete the task with at least a 75% performance level. A 75% performance level would mean that the user should have no more than 2 errors.

Time Performance: All members of this user group should be able to complete the task in less than 60 seconds. Since the information isn't present on the Knowledge Base site, and the information is actually contained on another Web site, it may take longer than normal for the user to locate the information. If the information was present on the Knowledge Base site (which it may be on the redesigned version), all users should be able to complete the task in less than 45 seconds.

User Satisfaction:
A) Completing the task: Since this task is somewhat important (2) to this user group, it makes sense that users be at least somewhat satisfied (2) with the amount of effort it took to complete the task.
B) The content/information: Members of this user group should be at least somewhat satisfied (2) with the information found while completing the task. The information isn't maintained by the Knowledge Base Web site, rather by the W3C site. However, it is important for Knowledge Base to ensure that the information linked to is relevant and up to date.

User Group 2: Project Managers.

Importance: 1 -not important. Project managers, whether managing Web related project or not, will not be involved in the design and development of Web pages using frames. Ideally, they would have an understanding of the use of frames on the Web. However, compared to the other user groups, this task is not important to project managers.

Task Performance: All members of this user group should be able to complete the task with at least a 50% performance level. A 50% performance level would mean that the user should have no more than 3 errors.

Time Performance: All members of this user group should be able to complete the task in less than 90 seconds. The combination of the task not being very important to this user group, and the fact that the information is on another site, constitute the long acceptable time performance. If the information was present on the Knowledge Base site, all users should be able to complete the task in less than 60 seconds.

User Satisfaction:
A) Completing the task: Since this task is not important (1) to this user group, it's not that important that they are satisfied with the task. Therefore it is acceptable if members of this user group are not satisfied (1) with what it took to complete the task.

B) The content/information: Since this task is not important (1) to this user group, it's not that important that they are satisfied with the task. Therefore it is acceptable if members of this user group are not satisfied with the information they find upon completing the task.

User Group 3: Hardware, software, Web site and intranet site designers.

Importance: 3 - extremely important. Web and intranet designers need to understand the issues surrounding the use of frames on the Web. Frames can cause a variety of accessibility and usability problems for users. Although the designers will not be doing the coding that titles each frame, they need to recognize that it needs to be done. Designers and developers sometimes have a crossover of job functions and perform the duties of both positions.

Task Performance: All members of this user group should be able to complete the task with a 100% performance level. A 100% performance level would mean that the user should have no more than 1 error.

Time Performance: Finding the information from this task is extremely important to this user group, therefore all members of this user group should be able to complete the task in less than 45 seconds. If the information was present on the Knowledge Base site, all users should be able to complete the task in less than 30 seconds.

User Satisfaction:
A) Completing the task: Since this task extremely important (3) to this user group, it's important that they are extremely satisfied (3) with the effort it takes to complete the task.

B) The content/information: Due to the importance of the task, all users of this group should be extremely satisfied (3) with the information they find after completing this task.
