A Parametric Management Tool for Estimating Simulator Software Size.
Abstract
This research investigated the causes of escalating software costs relative to Aircrew Training Devices (simulators) and resulted in a software sizing tool useful in reversing the cost growth trend. The hypothesis was that a collective software sizing estimate, aggregated and stadardized at the functional level, would provide a more reliable estimate of simulator software size. Investigation disclosed that the heuristic sizing techniques being used were inadequate. There was no organized empirical data-base to suport a formalized software sizing process. A software management model called SIMSIZ, including a supporting data-base, was designed and developed. The model's primary function is to assist software engineers in making realistic evaluations of the size of contractor's proposed software packages. It was concluded that a major cause of software program delays has been a growth trend in software size during program development. SIMSIZ has demonstrated that several software project under development are undersized. The researchers recommend establishing a requirement to standardize simulator software development and reporting at the functional level. (Author)
