SISO Organization
SISO's organizational structure, policies, and procedures are detailed in Administrative Document SISO-ADM-002-2011, SISO Policies & Procedures. Very briefly, SISO's structure includes
  • The Executive Committee (EXCOM), the policy body that provides overall governance and strategic planning.
  • 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.
  • 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.
  • Board of Directors (BOD), which is responsible for financial oversight of SISO and for SISO's contractual relationships with other organizations.
