Measurement of Business Rules Specified as Reusable Components: Exploratory Study of Its Impact on the Functional Size of Software Projects

When reusable software elements are defined in the requirements phase, this raises a number of issues for the measurement of their functional size, when a reusable element implements a business rule or a business sub process, for example. A case study is presented with project functional size measurement data to illustrate the impact of reuse on the resulting size and to determine criteria of reuse effectiveness and efficiency.
