Software sizing and costing models: a survey of empirical validation and comparison studies
Graham Tate, June M. Verner · Journal of Information Technology · 1990
Effective software cost and size estimation is essential for planning and resource allocation in software development. Recent empirical work which attempts to validate, or which compares, software size and cost estimation models and tools is surveyed. Some observations are made concerning the rather poor results frequently obtained and the need for calibration of models for specific development environments.
