Product line practices promise to reduce development and maintenance efforts, to improve the productivity and to reduce the time to market by systematic reuse of commonalities and variabilities. However, in order to reap the fruits of exploiting those, an upfront investment is required.

We discuss experiences made and show that the break-even was reached with the 4th product derivation.
