Unformatted text preview: cumentation and supporting LSAR data tables contain large quantities of data. Making use of these data in a timely manner is currently difficult because changes occur often and rapidly during definition, design, and development (Phases B through D). Continuous Acquisition and Life-Cycle Support (CALS)—changed in 1993 from Computer-Aided Acquisition and Logistics Support—technology can reduce this dilemma by improving the digital exchange of data across NASA field centers and between NASA and its contractors. Initial CALS efforts within the logistics engineering community focused on developing CALS digital data exchange standards; current emphasis has shifted to database integration and product definition standards, such as STEP (Standard for the Exchange of Product) Model Data. CALS represents a shift from a paper- (and labor-) intensive environment to a highly automated and integrated one. Concommitant with that are expected benefits in reduced design and development time and costs, and in the improved quality Can NASA Benefit from CALS? The DoD CALS program was initiated in 1985, since 1988, it has been required on new DoD systems. According to Clark, potential DOD-wide savings from CALS exceeds $160M (FY92$). However, GAO studies have been critical of DoD's CALS’ implementation. These criticisms focused on CALS' limited ability to share information among users. For NASA field centers to realize savings from CALS, new enabling investments in hardware, software, and training may be required. While many of NASA's larger contractors have already installed CALS technology, the system engineer wishing to employ CALS must recognize that both GALS and non-CALS approaches may be needed to interact with small business suppliers, and that proprietary contractor data, even when digitized, needs to be protected. improved quality of ILS products and decisions. CALS cost savings accrue primarily in three areas: concurrent engineering, configuration control, and ILS functions. In a concurrent engineering environment, NASA's multi-disci...
