US Patent 11526391 Real-time cognitive root cause analysis (CRCA) computing

An ordered set of root cause analysis (RCA) document entry criteria is identified. RCA input segments are specified using unstructured natural language input, including at least: incident descriptive elements, a single problem statement, a set of why questions and answers, and a single cause categorization. A guided input sequence of the RCA input segments is performed interactively with a user. Quality indicators of content of user input entered during a respective RCA input segment are determined using a scoring algorithm, and the user is assisted with improving precision and consistency of the user input. Responsive to a threshold of consistent user input across the RCA input segments resulting in identification of a single cause categorization of an information technology (IT) problem, an RCA document is generated that identifies the single cause categorization of the new IT problem.
