Calibration Of The Price S Software Cost Model, James C. Galonsky
Theses and Dissertations
As more Department of Defense resources are being allocated toward software development, the necessity to accurately plan for software costs has become critical. Obtaining reliable estimates from software cost models, like PRICE S, can be a problem when input parameters are not precisely defined or calibrated. This research effort centered on refining Productivity Factor (PROFAC) values for defense industry applications. The Space and Missile Systems Center Database was used to calibrate PROFAC values for eleven stratified data sets: military ground, military mobile, missile, unmanned space, Ada, Assembly, C, COBOL, FORTRAN, JOVIAL, and PASCAL. The accuracy of the calibrations was determined …
