Description

This is a summary of work presented to the Level B Space Station Program Office at Johnson Space Center related to customer requirements definition and their impact for Space Station design. The study was global in scope, querying the range of potential Station users for their ranked requirements for access to Station capabilities. User groups are identified based on their common set of functional requirements for Station services, and group needs were ranked according to level of utility for each unique Space Station capability. Analysis of the design drivers identified by the utility scores was conducted, resulting in a determination of which Station capabilities are in greatest demand, and where major technical commonalities and incompatibilities exist between user groups. This analysis provides a mechanism whereby NASA managers can evaluate the impact of design tradeoffs for the Station's customer community.

Major conclusions of the study include: 1) the need to base design choices on functional user group needs in order to account for currently unknown users; 2) emphasizing operational flexibility and minimizing life cycle costs in order to provide a "user-friendly" system; 3) scarring the Station to allow for potential external resource enhancements provided by international partners or commercial firms; and 4) establishing an IOC operating envelope based on the identified "core" capabilities with the greatest utility to the widest user community. In particular, this means optimizing for users who have a primary requirement for manned interaction on the Station, and providing for users whose requirements are not met within the IOC envelope through growth configurations or logistical support for their activities outside the core manned facility.
