Short Title: Usability
Responsible HRP Element: Space Human Factors and Habitability
Collaborating Org(s):
Funding Status: Completed - Task completed and produced a deliverable
Procurement Mechanism(s):
Directed
Aims:
  1. Develop legibility verification methodology for hardware labels
  2. Develop consistency scale for a case study
  3. Field testing with consistency scale
  4. Field testing with legibility methodology
  5. Evaluation of factors affecting maneuverability
  6. Field testing with the maneuverability scale at DRATS
  7. Measures of efficiency, effectiveness and satisfaction

The Usability Task completed all aims, contributing to closure of the HCI requirements gap.  As a result of the project, standards were added to NASA-STD-3001 and the first ever Usability requirement was approved for inclusion in the Human-Systems Integration Requirements Document (HSIR) for Constellation. The process for collecting and analyzing error rates developed as part of this DRP provided the basis for the Usability Process in the CCT-1002 Commercial Human-Systems Integration Process document.
