FROM/BCS is a promising product line engineering method which has the advantage of integrating variability in software development diagrams or models and to explicitly give variants of variation points. This approach has been proposed to allow transposition of industrial chain production to software world. However, to come closer to the real reduction of cost and risk and taking into consideration the evolution of software requirements, the method have to be improved since it does not give a way to set characteristics so as to derive a specific product easily. To address this issue in this paper, through the concept of command, we give a modeling approach that allows requirements fixation. In the new approach named CODA (Command Oriented Derivation Approach), given a requirement variation, the specific product architecture is derived fluently from the generic architecture and the command specification.
