SEER-SEM to COCOMO II Factor Convertor
Previously [Madachy, Boehm, 2008], Rosetta Stones have been developed for converting COCOMO II estimate inputs into corresponding SEER-SEM or True S inputs, or vice-versa. Most of those Rosetta Stone mappings between factors are one-to-one, but some are one-to-many. Often these factors use disproportionate definitions. Additionally, each model contains factors that unique to that model.
This paper describes a tool that provides automation of factor transformations using one of those Rosetta Stones, specifically, the mapping from SEER-SEM to COCOMO II.
Techniques are detailed to map between disproportionate factor definitions. Following specifying the three Effort Multipliers not mapped from SEER-SEM (Personnel Continuity, Data Base Size, and Documentation) a composite Effort Multiplier is obtained.
