Information Requirements

Obviously, I want information supplied by the flight tracker to be:

1) Accurate
That is there are no mistakes regarding times (including mistakes with time zones, summer/winter time change, 24/12 hour format, day+1 etc.), flight status, and other information.

2) Up-to-date
We need real-time tracking and automatic updates.

3) Full
Would be great to have all the required information in one place.

4) Easy to find
Maximum simplicity for finding the most needed information (status, times).

5) Easy to get
Even though it is easy to find, it may not be easy to access and receive — that is to view, save, and have it updated.

6) Accessible from any place
What if you need to look up the info in a taxi on your way to the airport?

7) Accessible any time
This can be a redundant requirement if 6) is valid. But it still needs checking especially regarding upgrades to the service and its reliability.

8) Accessible from any medium
It means access from:

• the Internet
• a phone call
• a mobile service (SMS/USSD/WAP etc.)
