Compare with evidence.

Methods and worked examples for decisions spread across offers, revisions, emails and files. Each guide separates what the sources state from what still requires judgment.

Compare your sources

Comparison Lab

Synthetic, reproducible examples that show the source terms, the meaningful differences and the limits of the conclusion.

Methods

Use the right kind of comparison, keep provenance visible and know when the available evidence cannot support a conclusion.

Decision workflows

Start with the situation you face, then move directly into the relevant comparison.

Compare vendor quotes

Check price, delivery, scope, exclusions and payment timing before choosing a supplier.

Compare PDF revisions

Find consequential changes between versions and return to the passages that support them.
