Start with a purpose.
Use information that is relevant to a clear commercial question. More data is useful when it improves understanding and supports an appropriate decision.
Responsible Data
The value of data depends on how it is selected, interpreted and used. These principles guide our view of responsible analysis.

Use information that is relevant to a clear commercial question. More data is useful when it improves understanding and supports an appropriate decision.
Consider where information comes from, what it represents and what it may leave out. Coverage, recency and uncertainty all affect the conclusions that can be drawn.
Respect privacy, confidentiality and the conditions attached to information. Responsible use requires attention to appropriate access, proportionate detail and the purpose of the analysis.
Make assumptions and limitations visible. Analysis should support considered human decisions, with room to question the evidence and revisit a conclusion.
