Task Analysis and Assumption

Tasks:
We idetify the main tasks based on our previous study.

The system should provide the following tasks, such as:
•User login/logoff
•User profile
•Search: for user to search a certain idea
•User can look up and comment on other users suggestions as well as vote on them using their IDs or anonymous
•User can propose his own suggestion
•Picture upload: The system should provide picture upload feature which can be used to draw up sketch for users
•Multi-language support: for the users will come from the world, the system should be provided at least two languages. One is English, the other one is local language
•Help

Assumptions:(What we need to improve in our design)
The old system has some functions already installed that work well. However there are issues with other parts.
1. Already implemented and work well
The view ideas function works well in the old system. It has a nice overview and is easy to understand. The use of the desktop metaphor is useful.
2. Been implemented but need to be improved
The overall GUI is not very intuitative, the user gets confused and might avoid use the system.
3. Haven’t been implemented
The most important thing to be implement is the english version of the site. Since the system is used in an international airport, it is really important not to forget the english talking people, both passengers and employees.
