The method can be organized into four steps:
1. Identify the judgment known in the original case.
2. List the plausible causal properties.
3. Test each candidate for cases where the property is present but the judgment absent, or the reverse.
4. Eliminate unsuitable alternatives and evaluate the surviving candidate.
If the list of possible causes is incomplete, the final survivor is not proved to be the cause merely because other listed candidates were rejected.
