Resource utilization during software development

This paper discusses resource utilition over the lie cycle of software development and diiusses the rote that the current “waterfall” model plays in the actua! software life cycle. Software production in the NASA environment was analyzed to measure these differences. The data from 13 diierent pmjects were collected by the Software Engineering bboratory at NASA Goddard Space Fliiht Center and analyzed for similarities and differences. me results indicate that the waterfall model is not very reelistic in prectice, and that as technology introduces further perturbations to this model with wncepts like executable specifications, rapid prototyping, and wide-spectrum languages, we need to modify our model of this process,
