Component-by-Component Error Diagnosis in a Three-Stage Workflow
To identify which part of a three-stage workflow is causing an error, substitute one intermediate output at a time with a known-correct version and leave the other stages unchanged. If replacing A's output makes the final result correct, A is the likely source of the mistake. If the error remains, test B in the same way. If B also does not fix the problem, the remaining stage C is the most likely cause.
