2. 2 Artificial Intelligence Applications Institute Centre for Intelligent Systems and their Applications Shared Task Model – Mixed initiative model of “mutually constraining the space of products”. Shared Space of Options – for the product. Shared Model of Agent Capabilities - handlers for issues, functional capabilities and constraint managers. Shared Understanding of Authority – management of the authority to handle issues and act which may take into account options. Shared Product Model – using constraints on the space of products. Shared Task and Activity Concepts for Mixed-Initiative Work User Role 1 User Role 3 Other Agents User Role 2
