Abstract : The purpose of this research was to identify the impact of variables in the Operational Flight Program (OFP) software development phase upon OFP software support. Investigate questions included identifying: 1) development and support models, tools, and techniques in the literature; 2) specific variables of these models, tools, or techniques; and 3) the impact of these variables upon software support costs. A background review covered software and system life cycles, modern design practices or techniques, and software tools and models. A methodology was also developed for model comparison. A literature review then covered software tools, techniques, and taxonomies along with the Avionics Integration Support Facility. A taxonomy was then developed for technique variables according to DoD Standard-2167 development phases, as follows: requirements analysis (RA), preliminary design (PD), detailed design (DD), coding and unit testing (CD); computer software component integration and testing (CSC); and finally, computer system configuration item testing (CSCI). These variables were rated from the most ot least important on their impact in reducing support costs. Final recommendations encouraged: 1) use of non-proprietary models; 2) increased management participation during early development phases; 3) use of two models during development; and 4) follow-on research to substantiate findings.
