It reflects changes in global output, employment, new business, backlogs and prices. The Global Services PMI is seasonally adjusted at the national level to control for varying seasonal patterns in each country and is produced by J.P. Morgan and Markit in association with ISM and the International Federation of Purchasing and supply Management (IFPSM).
