5D Task Analysis Visualization Tool, Phase II

Completed Technology Project

Project Introduction

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 management innovation, configuration management, and loosely-coupled reusable libraries provides a unified data-driven 5D model portraying total complexity (risk, resources, workload, and duration) and process flow including conditional paths. Critical path and conflicts are accentuated with user controlled sensitivity thresholds for filters, indicators, notifications. The software tool promises increased awareness for human factors, project management, operations personnel, and system designers improving efficiency, accuracy, and understanding. Robotic activity developers and small spacecraft swarming coordinators are provided with an intuitive 3D design representation. These improvements will lead directly to improved system design, optimization of human and system allocations and conservation of resources for long-duration missions including sustainable habitats. The 5D-TAV tool's open architecture integrates open source software to provide the 2D rendering and 3D model views, filters, rotations, and controls necessary for successful task analysis optimization to ensure mission success.
