| This research presents the development and evaluation of the productivity potential of LiquidBriefing, an integrated briefing system for authors, briefers, and audience members to use for decision making Requirements for the system are derived from a literature review and a series of role-specific interviews. Key functions include wiki-based structured document authoring, generating slides automatically from document content, generating concept maps from document structure, dynamic briefing navigation using the concept map and hyperlinks, and real-time audience feedback using the concept map. The software prototype was developed over three iterations, guided by observations and participant feedback. Productivity evaluation encompasses several dimensions, including time savings, quality of results, enhanced interaction, and information retention. Results from six experiments indicated that the system can improve productivity for: authors through increased document scope and easier collaboration; briefers through improved briefing flow and increased audience interaction; and audiences through easier interaction and improved briefing flow. |
