Abstract
This article presents a parametric software cost estimation model prepared for JPL Deep Space Network (DSN) Data Systems implementation tasks. The resource estimation model incorporates principles and data from a number of existing models, such as those of the General Research Corp., Doty Associates, IBM (Walston-Felix), Rome Air Force Development Center, University of Maryland, and Rayleigh-Norden-Putnam. The model calibrates task magnitude and difficulty, development environment, and software technology effects through prompted responses to a set of approximately 50 questions, Parameters in the model are adjusted to fit JPL software life-cycle statistics. The estimation model output scales a standard DSN Work Breakdown Structure skeleton, which is then input into a PERT/CPM system, producing a detailed schedule and resource budget for the project being planned.
