Established in 1915, the organization has been at the forefront of the supply management industry for over 100 years, promoting best practices and professional certifications throughout the industry.

ISM believes that professional certification is a key enabler of quality, efficient, and secure sourcing and supply chains. The organization offers two certifications: Certified Professional in Supply Management (CPSM) and Certified Professional in Supplier Diversity (CPSD).

The CPSD certification is offered to recognize supply management professionals with expertise in the management of supplier diversity.

In addition to offering professional certifications, ISM provides numerous educational and research opportunities. Its ISM Manufacturing Report on Business is considered a leading economic indicator, as it tracks purchasing managers' indexes and also creates forecasts regarding global economies.
