Applying it

Writing Quality Measurement Model

Twelve weighted measures, scored nought to four. Four of them are gates: below two, the document fails regardless of the average.

weighted_score = sum(metric_score × weight) / sum(4 × weight) × 100

The twelve metrics

The twelve quality metrics, their weights and questions
Metric	Weight	Gate	Question
accuracy	2	Gate	Does every proposition preserve intended and supportable meaning?
grammar	1	—	Are required morphological and syntactic relations well formed for the target variety?
clarity	1.5	—	Can the audience recover referents, relations, scope, and action without preventable rereading?
usability	2	—	Can the reader find, understand, and use the content for the intended task?
structure	1	—	Does order reveal the document’s questions, hierarchy, and progression?
evidence	2	Gate	Do claims have appropriate, proximate, bounded support?
accessibility	2	Gate	Can readers with varied sensory, cognitive, language, and input conditions access the meaning and action?
voice fit	0.75	—	Does the prose maintain the declared relationship and adapt tone to the situation?
rhythm	0.5	—	Do syntax, length, sound, stress, and repetition support attention and effect?
ethics	2	Gate	Does the text preserve truth, dignity, consent, privacy, and meaningful choice?
maintainability	0.75	—	Can volatile facts, terms, rules, and versions be updated without drift?
outcome	2	—	Did the intended reader state or behavior change as intended without unacceptable harm?

Then: fail regardless of average

Else: calculate weighted score

The measured outcomes the model treats as evidence that the writing worked.
