TFL mobile web site user journey
In Figure 2-2 you can see the TFL Journey Planner mobile web site. The user
journey above depicts a worst-case scenario. This user is on the move, and is
prone to making data entry mistakes. As a result of this, the user must go
through two extra page loads with more form fields in order to complete the
task.
What is wrong with having two extra pages to help the user with validation? Two
extra pages will equate to 4+ seconds of loading time over 3G. You must also
factor in the time required for a user to process the page and respond to it.
