Research Methodology

Evidence hierarchy

1. Current official product, technical, regulatory, and company documentation.
2. Verifiable implementation evidence and named operator references where public.
3. Direct vendor clarification, clearly labelled when it cannot be independently confirmed.
4. Secondary reporting used for context, never as the sole basis for a material capability claim.

How comparisons are built

Every comparison starts with reader intent, operator profile, solution layer, and an explicit requirement matrix. Unlike delivery models are not forced into one score without explaining the trade-off.

Uncertainty and updates

Roadmap items, market-specific availability, missing pricing, and unverified claims are marked as limitations. Material pages show an update date and are reviewed when product scope or evidence changes.
