Divides into
2 components at level 2.
Rules
Whether this division survives the six rules.
Rules 1, 5 and 6 are checked by the validator and reported here. Rules 2, 3 and 4 are judgements about meaning and cannot be automated — no state is claimed for them. The rules themselves are set out in the method.
At most seven
Divides into 2 components.
Mutually exclusive
A judgement about whether the parts overlap. Not automated.
Collectively exhaustive
A judgement about what the parts leave out. Not automated.
Equal abstraction
A judgement about whether the parts answer the same question type. Not automated.
Decomposable or terminal
Divides into 2 parts.
Justified in writing
