NASA requires a consistent analytical foundation to select and monitor R&D tasks that support new system concepts for future missions, and this approach can also be applied to other areas such as system architectures, risk reduction, and human‑machine task allocation. The paper describes an early‑stage approach for selecting NASA technology portfolios and presents illustrative examples. The approach is designed to be applicable across different levels of abstraction—from formulation to operations—and to various organizational scopes, from single projects to the entire agency. © 2004 Wiley Periodicals, Inc., Syst Eng 7: 285–302.
Abstract There is an important need for a consistent analytical foundation supporting the selection and monitoring of R&D tasks that support new system concepts that enable future NASA missions. This capability should be applicable at various degrees of abstraction, depending upon whether one is interested in formulation, development, or operations. It should also be applicable to a single project, a program comprised of a group of projects, an enterprise typically including multiple programs, and the overall agency itself. Emphasis here is on technology selection and new initiatives, but the same approach can be generalized to other applications, dealing, for example, with new system architectures, risk reduction, and task allocation among humans and machines. The purpose of this paper is to describe one such approach, which is in its early stages of implementation within NASA programs, and to discuss several illustrative examples. © 2004 Wiley Periodicals, Inc.
