The technical work is done through Technical Committees and Working Groups of Technical Committees. Each Technical Committee is composed of one representative of each member organization, whereas Working Groups consist of specialists in the field who are appointed as individuals independent of nationality. Its aim is to improve the quality of numerical computation by promoting the development and availability of sound numerical software. The group meets roughly once a year. Reports on current and completed activities are given and discussed at the meetings, and areas of activity and the proper means of achieving results are defined.
Most activities take the form of projects.
One or several members of the group assume the responsibility to pursue a given subject matter in collaboration with other scientists in the field. Results of the projects are usually published. All projects are performed on a completely voluntary basis. Another activity is the arrangement of working conferences. It is necessary to limit the number of members of each working group in order to obtain a productive group, one that can meet and exchange ideas without demanding organizational arrangements.
