The creation of a five-dimensional task analysis visualization (5D-TAV) software tool for Task Analysis and Workload Planning using multi-dimensional visualization will have significant positive impacts on the optimization of human-centered design at NASA. Recent research identified a 40% improvement in task analysis accuracy and efficiency using 3D visualization. Employing enterprise data integration and management innovation, configuration management, and loosely-coupled reusable libraries provides a single 5D model accentuating critical path, risk to task completion, staff selection, complexity, and conflicts. Such a software tool promises increased awareness for project management, operations personnel, and designers, improving efficiency and decision making, and reducing risk. These improvements will lead directly to improved system design and utilization of crew, as well as optimization of human and system allocations. The 5D-TAV tool's proposed integrated architecture incorporating available commercial tools provides the views, filters, rotations, and controls necessary for successful task analysis visualization and data management to increase mission success.
