Start with scope
Translate user requirements into a transparent selection path.
How we structure the research
- Describe the outcome you need
- List non-negotiable requirements and constraints
- Separate essentials from preferences
- Ask for evidence against each selection criterion
Choose suitable sources
Use official documentation, original research and relevant technical references. State versions, dates, units and important conditions alongside the claim. Manufacturer documentation can establish what that manufacturer specifies; broader claims may require independent evidence.
Distinguish evidence and illustration
Diagrams on the site may simplify a concept. They are illustrative, not test records, engineering drawings or certification evidence. Examples are not customer case studies unless clearly substantiated.
Keep uncertainty visible
Show assumptions and exceptions. Link to the source that supports a claim, and state when evidence is incomplete or conflicting.
