Feature model

In software development, a feature model is a compact representation of all the products of the <a href="/facts/Software_Product_Line/I6SIMRb7">Software Product Line</a> (SPL) in terms of "features". Feature models are visually represented by means of feature diagrams. Feature models are widely used during the whole product line development process and are commonly used as input to produce other assets such as documents, architecture definition, or pieces of code. 
A SPL is a family of related programs. When the units of program construction are features—increments in program functionality or development—every program in an SPL is identified by a unique and legal combination of features, and vice versa.
Feature models were first introduced in the <a href="/facts/Feature-Oriented_Domain_Analysis/tU1JCcmf">Feature-Oriented Domain Analysis</a> (FODA) method by Kang in 1990. Since then, feature modeling has been widely adopted by the software product line community and a number of extensions have been proposed.
