Identify
Keep the full model name and version in the file.
Words that sharpen
the question.
A short guide to the language used in our documentation records. Open a term to see why it matters.
Claim+
A statement that can be checked against evidence.
A published specification is a claim until its supporting method and context can be examined.
Documentation analysis+
An examination of existing records and published material.
It does not substitute for testing a physical sample. Our current model files use this method.
Evidence+
Material that supports or challenges a specific statement.
Evidence must fit the question. A manufacturer image can show presentation but cannot establish battery performance.
Model identity+
The exact name and version to which a record applies.
Family names and similar packaging can hide differences. Keep the full model name attached to each source.
Provenance+
The origin and history of a source or item of evidence.
Record who published it, where it appeared and when it was accessed.
Reproducibility+
The ability to repeat a documented method and assess its result.
A useful test record describes the sample, conditions, equipment and limitations.
Uncertainty+
What remains unknown or unresolved in an interpretation.
Stating an uncertainty helps readers avoid treating an assumption as a measurement.
