A Function Point - like Measure for Object

We present a method for estimating the size, and consequently eeort and duration , of object oriented software development projects. Diierent estimates may be made in diierent phases of the development process, according to the available information. We deene an adaptation of traditional function points, called \Object Oriented Function Points", to enable the measurement of object oriented analysis and design speciications. Tools have been constructed to automate the counting method. The novel aspect of our method is its exibility. An organisation can experiment with diierent counting policies, to nd the most accurate predictors of size, eeort, etc. in its environment. The method and preliminary results of its application in an industrial environment are presented and discussed.
