According to Fortune, to pick the 20 most-admired global firms overall, businesspeople were asked to vote for the companies from any industry.
"To create the top 20, an overall list of Most Admired Companies, the Hay Group asked 3,721 executives, directors, and securities analysts who had responded to the industry surveys to select the ten companies they admired the most."
They chose from a list made up of the companies that ranked in the top 25 per cent in last year's survey, plus those that finished in the top 20 per cent of their industry, the magazine added.
