Abstract: Methods and systems for collaborative evidence-based problem investigation and resolution are described. The method includes receiving data related with fault that has occurred in faulty system. The data includes symptoms and details associated with each symptom. The method includes arranging data in symptoms table. The symptoms table includes rows for describing symptoms and columns for defining details associated with each symptom. The method includes facilitating concurrent update of symptoms table by users in order to indicate clues or update details, and causing provisioning of cause-effect UI to facilitate creation of cause-effect graph using clues. The method includes creating cause-tree/fishbone diagram based in part on at least one of: causes defined by users, symptoms and clues defined in symptoms table, components of faulty system, and historical data from prior problem investigations.
