A method designed to produce evidence that holds.
Every engagement follows the same analytical discipline. It is what allows our conclusions to survive audit, consultation and review.
Frame
We establish the decision at stake, the evidence it requires, and the standard that evidence must meet to be defensible.
Evidence
We assemble and interrogate the data — official statistics, proprietary sources and primary research — making every assumption explicit.
Analyse
We apply established methods with documented rigour, testing the judgements on which the conclusion actually rests.
Decide
We translate analysis into clear, actionable findings — reported with appropriate uncertainty, built to withstand scrutiny.
Standards we hold our work to.
Credibility is not claimed; it is demonstrated through method. These are the standards that make our analysis defensible where it matters most.
Public sector analytical standards
We hold our work to the standards expected of government analysis — including HM Treasury Green Book appraisal and recognised evaluation guidance.
Defensible, documented methodology
Every assumption is stated and every method documented, so that conclusions can be examined, audited and relied upon under scrutiny.
Evidence-led, quantitative capability
Conclusions are grounded in data and quantitative method — econometric modelling, cost-effectiveness analysis and reproducible pipelines.
Reproducible by design
Analysis is built to be reproduced and maintained, including by our clients’ own teams — evidence that outlasts the engagement.
Considering an engagement?
We work with a limited number of organisations at any one time. If you are weighing a decision that would benefit from independent analysis, we would welcome an early, confidential conversation.
