James H. Herd, John N. Postak, William E. Russell, Kenneth R. Stewart · 1977
The study identified factors that have an adverse effect on software cost estimates, determined their impact on software cost estimates, discussed methods for controlling the effect of these factors, and developed an overall methodology for estimating the costs of software development. In addition to a generalized model for estimating software development costs, separate models have been generated for estimating the development cost of command and control, scientific, utility, and business software.
