جزییات کتاب
The study will show that even though the system is designed as a replica, there are some important differences between the systems. While the previous system fulfils the demands of usability in EN-ISO 9241-110 and the widely used Nielsen heuristics, the new systems Reskassa does not. The cause can be traced to the shift of where the selection of tickets is performed, the removal of the tickets themselves as an information channel and weakened error preventions. Previously the user told the system where to go and the system provided the user with a correct ticket. In the new system the user must tell the system which ticket is the correct one for the intended journeys. This shift of responsibility has been made without changing the information given from the system through its basic channels; the staff and the machinery. By making the tickets digitally stored without adapting the information flow to the new needs has created a system that doesn’t provide the user with its needed information when buying tickets and thus making the system difficult and prone to errors. There are however several strategies available to improve the systems information flow and to transform the system to a user-aiding design.
