Main features
Analyze home pages of 50 U. S. states
(www.state.md.us)
Size (source code, gifs, total bytes)
Navigation (incoming & outgoing links, style of navigation)
Graphics (governor’s picture, state seal, statehouse picture,
scenery picture, map, use of tables and frames )
Services (privacy policy, universal usability statement, contact
information, online help, search box )
Design goals: Improve E-government
Requirements:
better delivery of government services to citizens
improved interactions with business and industry
citizen empowerment through access to information
more efficient government management
Solution - set of guidelines & metrics:
solve architectural and design problems
lay out requirements for content
improve the users’ experience with the web site
minimize time & effort to access information on similarly web sites
Size metrics: Reduce Download Time
Methodology: byte count
source of the home pages
images on the home pages
largest image on the home pages
Results:
smallest total byte count - Vermont (42k)
largest total byte count - Washington (274k)
largest image - Nevada (84k)
Navigation metrics: incoming & outgoing links
Methodology: number of
outgoing links for the home page
incoming links for the whole web site of each state
Results:
outgoing links
• Delaware & Nevada (10)  Vermont (115)
incoming links
• Washington (627)  Tennessee (72138)
