The origin of the Services ISM
Report On Business can be traced to 1996. Over the years, there had been a shift in ISM's membership from nearly 100 percent manufacturing firms in the 1930s to almost 50 percent services firms by 1996 such as: •
Financial services •
Health services •
Transportation • Communication •
Public administration Also, by this time, the services sector of the U.S. economy was responsible for about 80 percent of gross domestic product (GDP), the primary measure of economic activity. There also was a trend toward the services share of the economy continuing to increase in the future. While the existing ISM
Manufacturing Report On Business was well-accepted as one of the primary indicators of overall U.S. economic activity, ISM felt that to fully capture all economic activity and to enable all members of ISM to participate in the survey, a services version of the
Report On Business should be considered. As a result, in 1996, it formed a committee to explore the development of the Services ISM
Report On Business. By the spring of 1997 the pilot was considered successful. In July of that year, routine monthly data collection began. Monthly public reporting and release of data debuted in June 1998 with the release of the May 1998 data and ten months of data history. The Services ISM
Report On Business is released on the third business day of each month, and is based on data compiled from monthly surveys sent to purchasing executives working in the services industries across the country. The process, content and format of the report parallel that of the manufacturing report with only a few differences. Each month, the survey responses reflect change, if any, in the current month's report compared to the previous month. The report covers: • Services Index • Business Activity • New Orders • Backlog of Orders • New Export Orders • Inventory Change • Inventory Sentiment • Imports • Prices • Employment • Supplier Deliveries The Services Index which is a weighted composite index for services data (similar to the Purchasing Managers' Index (PMI)) was developed and first published in the January 2008 Non-Manufacturing ISM
Report On Business. This was not available prior to that date because there was insufficient services historical data to develop a composite index. ==Methodology==
