## Method and source

Arquestra Consulting Market Radar, built 2026-10-30 from TED (eForms) and national registers (France DECP/BOAMP, Spain PLACSP, Germany, Netherlands): public consulting awards from EUR 15,000 up of the last 24 months, classified by kind of work; work outside consulting left out. Names of one firm in several countries and spellings are merged; an award with several winners counts once for each. Value won: each award's value split between the firms it names, frameworks (their value is a ceiling) and values of EUR 150 M or more left out (the same definition as the market cards). Universities, research institutes and public bodies are not ranked as firms.
