Which technique is used to explore cause and effect relationships for a specific problem in projects?

The technique commonly used to explore cause and effect relationships in projects is the "root cause analysis" (RCA). RCA identifies the underlying reasons for a problem by systematically examining its contributing factors. Tools such as the fishbone diagram (Ishikawa) or the 5 Whys technique are often employed to visualize and analyze these relationships, helping teams pinpoint the root causes of issues to implement effective solutions.
