This paper presents an overview of NASA Langley research program in formal methods. The major goals of this work
are to make formal methods practical for use on life critical systems, and to orchestrate the transfer of this technology to U.S.
industry through use of carefully designed demonstration projects. Several direct technology transfer efforts have been
initiated that apply formal methods to critical subsystems of real aerospace computer systems. The research team consists of
five NASA civil servants and contractors from Odyssey Research Associates, SRI International, and VIGYAN Inc.

Concurrent Engineering for the Management of Research and Development

The Management of Research and Development (R&D) is facing the challenges of reducing time from R&D to customer,
reducing the cost of R&D, having higher accountability for results (improved quality), and increasing focus on customers.
Concurrent engineering (CE) has shown great success in the automotive and technology industries resulting in significant
decreases in cycle time, reduction of total cost, and increases in quality and reliability. This philosophy of concurrency can
have similar implications or benefits for the management of R&D organizations. Since most studies on the application of CE
have been performed in manufacturing environments, research into the benefits of CE into other environments is needed. This
paper presents research conducted at the NASA Glenn Research Center (GRC) investigating the application of CE in the
management of an R&D organization. In particular the paper emphasizes possible barriers and enhancers that this environment
presents to the successful implementation of CE. Preliminary results and recommendations are based on a series of interviews
and subsequent surveys, from which data has been gathered and analyzed as part of the GRC’s Continuous Improvement
Process.

Using the MCPLXS Generator for Technology Transfer
Moore, Arlene A.; Dean, Edwin B.; [1987]; 13 pp.; In English; No Copyright; Avail: CASI; A03, Hardcopy
The objective of this paper is to acquaint you with some of the approaches we are taking at Langley to incorporate
escalations (or de-escalations) of technology when modeling futuristic systems. Since we have a short turnaround between the
time we receive enough descriptive information to start estimating the project and when the estimate is needed (the
‘we-want-it-yesterday syndrome"), creativity is often necessary. There is not much time available for tool development.
It is expedient to use existing tools in an adaptive manner to model the situation at hand. Specifically, this paper describes the
use of the RCA PRICE MCPLXS Generator to incorporate technology transfer and technology escalation in estimates for
advanced space systems such as Shuttle II and NASA advanced technology vehicles. It is assumed that the reader is familiar
with the RCA PRICE family of models as well as the RCA PRICE utility programs such as SCPLX, PARAM, PARASYN,
and the MCPLXS Generator.
