Abstract: A computer-implemented method, system and computer usable program code for solving an application failure using social collaboration are provided. A search request to search a central repository of knowledge is received. The search request comprises a user identity and an application failure problem to be solved. The central repository of knowledge comprises data regarding attempts to solve an application failure problem compiled from registered users of the central repository of knowledge. A determination is made as to whether the application failure problem to be solved exists in the central repository. If the application failure problem to be solved exists within the central repository, search results for previous attempts at solving the application failure problem are collected. The search results are ranked based on a frequency of access and feedback from users and are grouped according to social groupings defined by the requester. The results are displayed to a requester.
