Spacecraft Software Cost Estimation: Striving for Excellence Through Parametric Models (A Review)

This paper provides an overview of software cost estimation, with particular reference to the software of embedded computer systems in spacecraft. The paper provides access to literature on the subject, reviews the major software estimation models with commercially available automated supporting tools, and indicates data items necessary for accurate estimation. A brief comment on the impact of the introduction of the Ada* language on future software development costs and sources of continuing information on software costing conclude this presentation.
