The Homeland Security Exercise and Evaluation Program (HSEEP) Design and Development System (DDS) is an online comprehensive planning tool designed to assist in the development, conduct, and evaluation of exercises. This interactive application provides suggested project timelines, templates, task and planning team lists, and associated guidance throughout an exercise design and development cycle. Planners may use the DDS to design discussion-based (seminars, workshops, tabletops and games) and operations-based (drill, functional, full-scale) exercises. Throughout the planning process, the DDS provides users with populatable templates and samples for all key and supporting exercise documentation. It also provides users customized dynamic task list tracking, design and development tips and instructions, HSEEP volume references, and definitions. Exercise documentation, created either from the DDS templates or otherwise, can be stored in a unique exercise-specific database on the DDS for all members of the planning team with the appropriate permissions to view and edit. A running status of exercise progress is tracked on both graphical and interactive timelines. (FEMA, HSEEP Toolkit DDS, Sep 13, 2007)
