SISO's governance structure consists of:

• The Executive Committee (EXCOM), the policy body that provides overall governance and strategic planning.
  
  
• The Standards Activity Committee (SAC), which oversees the development and support of products to support interoperability and reuse in the M&S community. The SAC manages the Product Development Groups (PDGs) and Product Support Groups (PSGs), which focus on the development and support of consensus-based standards and related products.
  
  
• The Conference Committee (CC), which organizes the Simulation Innovation Workshops and oversees several Conference Forums in which information and new ideas are exchanged within and across various components of the M&S community.
  
  
• A Board of Directors (BOD), which is responsible for financial oversight of SISO and for SISO's contractual relationships with other organizations.

SISO's organizational structure, policies, and procedures are detailed in Administrative Document SISO-ADM-002-2017, SISO Policies & Procedures.
