RCA Doctor teaches Root Cause Analysis by making students do it, not just read about it. Each scenario is a realistic IT support or software development incident. Students decide whether it needs RCA at all, write a precise problem statement, separate containment from root cause work, pick the relevant evidence and build a timeline.
They then run a 5 Whys chain where every link has to be backed by evidence. They also build a Fault Tree by choosing causes and AND/OR gates, then eliminate branches using what the logs show. Wrong turns have consequences inside the scenario, so “human error” and first-guess answers get challenged.
Choices and tree-building are marked automatically. Written justifications are checked against a keyword rubric, and students compare their answer with a model answer. At the end each student produces a printable RCA report with their scores, which they save as a PDF and hand in through Teams/Google Classroom/Moodle
It runs entirely in the browser with no accounts and no server. Progress is saved locally on the student’s own machine. It suits T-Level Digital and similar Level 3 courses, and it works as a formative activity rather than a secure summative test, because the scenario data ships with the app.
