Abstract

A software product line is a strategic investment for an organization. Besides the initial decision to use a product line approach other strategic decisions are made, including which variations to accommodate. In this paper we present an adaptation of an equation for computing option values. The equation can be used to understand the economic impact of adding a variation point to the product line architecture. The equation was exercised on multiple sets of hypothetical data and and produced the expected changes from one data set to another. In the future the equation will be validated with data from real projects. We describe some practical sources of values for the parameters of the equation.
