Tasks View traffic patterns over time Filter display by many variables Date Page Browser Entry page Error codes User statistics Purchasing behavior Referral page / Search terms
Data Automatic web server logs analyzed to identify patterns. Example: revitupracing [25/Apr/2006:10:33: ] "GET /stylesheet.css HTTP/1.1" " "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1;.NET CLR ;.NET CLR )"
Scenario of use Joe Corp. just launched some new products on their website and they want to know how that launch is effecting the traffic that views their existing products.
Evaluation Define detailed tasks Create paper prototypes for those tasks Observe users interacting with the paper prototype. Looking specifically for: Ease of use Accuracy User satisfactions Unforeseen applications that we might want to support
Risks Because of the complexity of our data set we may not be able to base our paper prototypes on real data, we may have to simulate typical data instead. Hypothermia
Design ideas Graphical display of traffic over time. Bar graph or something similar Filter the data with sliders bar grams based on the variables identified before. Option to toggle display of traffic between different metrics Page views Bandwidth usage etc.
