In I don't think it's fair to say the UI was actually designed at all. This is what's leftover from what committees and executives decided the application needed to do with no thought whatsoever to anyone who would actually be using it. Notice how the most relevant information for the technician is on the fourth tab over, in a tiny unsizeable window next to a massive expanse of empty space. Note that several of the tabs seem to be describing the same thing. Where do you go to find out what you have to do? 'description?' 'instructions?' 'sub-tasks?' 'change details?' Why not 'general?'
And this is just the tip of the iceberg. This thing was an enormous, slow, resource-hogging java applet that required internet explorer. It no offline mode yet booted you off every 15 minutes which sometimes made you close out of IE and clear the cache or else you couldn't log back in. The boot-off process involved the entire application leaping into the foreground interrupting anything else you might have been doing.
