The Institute for Supply Management in Tempe, Arizona.(ISM)began to produce the report for the US in 1948.The data for the index arecollected through a survey of 400 purchasing managers in the manufacturingsector on five different fields, namely, production level, new orders fromcustomers, speed of supplier deliveries, inventories and employment level.Respondents can report either better, same or worse conditions than previousmonths. For all these fields the percentage of respondents that reported betterconditions than the previous months is calculated. The five percentages aremultiplied by a weighing factor (the factors adding to 1) and are added.
