In this thesis, we investigated how a design solution could facilitate the user experience on YouTube for saving and re-finding their videos within Personal Information Management (PIM) by examining the strategies adopted by different user groups while saving and re-finding their YouTube videos. To validate the findings from the literature review, a contextual inquiry was conducted to gain deeper insights and enhance the overall user experience. Through the application of thematic analysis, distinctive patterns and indicators concerning different motivations under which user groups save and re-find their videos on YouTube were identified. These findings contribute to a better understanding of the motivation behind saving and re-finding YouTube videos in line with PIM practices. an interactive/design thinking method was deployed to come up with additional features that could possibly increase users' engagement regarding saving and re-finding of videos on YouTube. Participants appreciated our proposed functionalities for saving and re-finding videos but there were concerns regarding the design of filtering functionality and the notification feature was highly welcomed. Our prototypical solution demonstrated the value of providing these functionalities in a user-friendly way based on the test results and participant input.
