When drafting the information architecture it was necessary to split the entire course offering and house it under each college respectively: Since the colleges actively compete between them on certain types of courses such as short courses, it was a business requirement to silo them under their college.
But even as business requirements dictated fragmented course listings, there was a need and desire of 'cross-pollination' on other types of courses such as undergraduate and postgraduate. To mitigate the split we offered a course finder search function as part of the global, main navigation which is accessed from the entire website.
The initial course finder dropdown consisted just by a search field and a search action. After observing user behaviours and analysing statistics, we revised it to include pre-filters, eliminating one of the most common steps our users were taking once on the search results page.
In addition to the course finder dropdown search, a separate search widget component was designed.
The widget in contrast to the dropdown returned localised results. For example if a user was to access it from a London College of Communication page, he or she would get courses returned from that specific college. Options to widen the search were given once on the results page.
