Binary Decision Tree Example

Binary decision tree example.

A binary decision tree gives every decision two possible branches. It is useful when a process can be simplified into yes-or-no questions, such as basic support triage or eligibility checks. Start with the question that separates the largest groups, then make each child question more specific. Keep the leaf nodes as actions or outcomes so a reader knows what to do next. If a decision has more than two meaningful outcomes, use separate questions rather than forcing an unclear binary split.

需求

“Create a binary support decision tree: ask whether the user can sign in; if no, reset the password and then either sign in works or contact support; if yes, ask whether there is an error message, then check service status; a known incident leads to waiting for resolution, otherwise try another browser.”

接著試試Add a screenshot request before contacting support.Change the final browser step to clear browser data.
