<p>A bottom-up approach to software size estimation is described. It first identifies factors affecting software size, thus obtaining size explanation equations, and then seeks suitable predictors based on those explanation factors which can be used for size estimation. The approach, or model, is bottom-up in that it sizes individual software components or modules first, and then obtains subsystem and system sizes by summing component sizes. Since components may have different purposes and characteristics, the model allows for the partitioning of system components into several different types, each component type having different size explanation and estimation equations. The partitioning is not fixed, but depends on the particular software development technology. The model is applied to several different software systems, including both business applications and systems programs.</p>
