A clear framework for better decisions.

Document data lineage, update frequency, outlier handling, comparable selection and human review in this section.

Start with the evidence

For every number, identify the source and date. Separate verified facts from estimates, forecasts and opinion. Review all legal, regulatory and financial statements before publishing.
