The viability of using COCOMO in the special application software bidding and estimating process

The purpose of the author is to correlate actual data with COCOMO (constructive cost model) estimated values and determine if the COCOMO method accurately reflects documented program expenditures. Because spaceborne microprocessing is a relatively new arena, the primary constraint associated with developing a model is the limited available database. Data collection to support a statistical analysis is presented along with a discussion of calculated COCOMO results. In the analysis, the use of nonparametric statistics for small samples is addressed. Wilcoxon Signed-Rank and Kendall-Rank statistics support distribution free analyses of the data
