Paper Prototyping

After testing our paper prototypes on our classmates, we decided to apply the following design changes:

• It would be helpful to have the system include a predefined text in
  every mail the user sends, containing information regarding his person and
  the transaction,
  
• the test users reported that browsing through deep
  'directory'-structures can be exhaustive, so the path in order to reach a
  desired item should get shortened,
  
• a user gave us an advise to 'merge' deep and narrow category-structures
  if they only contain few items,
  
• the appearance of lists should be more consistent, e.g. the symbols
  used for enumeration,
  
• it would be desirable to have a little textual hint like "restrict to
  category" when creating (or editing) a search in order to accent the
  meaning of the selection fields on the page,
  
• the user should have the possibility to restrict a search to more than
  one category,
  
• one "tester" requested the possibility of using pdf-files, for the
  description of the products,
  
• the trashcan should be moved from the 'Communication' page to the main
  screen,
  
• offers should be activated or deactivated arbitrarily,
  
• within the section "myOffers"  an additional information concerning the
  number of new messages should be displayed (feedback!),
  
• in the communication center a button for buying immediately could be
  offered,
  
• at last simplicity of use would be enhanced through empowering the
  central control to delete old entries automatically.
