The EXCOM is responsible for reviewing and promulgating the SISO Vision Statement, which is formally reviewed and voted on by the EXCOM every three years, at a minimum. Within three months of each formal review, the EXCOM publishes a three-year strategic plan covering meetings and standards activities, as well as other special topics such as outreach. This strategic plan utilizes the SISO Vision Statement as a framework and guide for planning broad activities of SISO; it also emphasizes any special areas of the SISO Vision Statement (such as new important functional needs, areas of education and outreach) and provides guidance for on-going activities, including management of SISO, Inc. Detailed aspects of this plan are implemented by the EXCOM and any other groups formed by the EXCOM for these specific purposes.
From a policy perspective, the EXCOM oversees the activities of SAC and its groups to ensure that high quality products are produced in a timely and responsive manner as needed by the broad modeling and simulation community. Likewise, the EXCOM oversees the activities of the CC and its various forums.
The EXCOM oversees the general election procedures of SISO to ensure a suitable number and distribution of qualified participants for each election, the fairness and integrity of the process, and adherence to schedule. The EXCOM may create a sub-committee to carry out this function and report to the EXCOM at large.
The EXCOM oversees the recognition of SISO members for specific or continuing service to the community or organization.
