Recently, situational method engineering (SME) has become more and more popular. Due to the fact that different situations require different methods, SME offers a flexible adaptation of methods. Furthermore, various approaches for the identification of services within service-oriented architectures have been proposed in the last few years. However, none of them provide a significant degree of situation-specific adaptability. Goal of this paper is to develop a meta model that can be used to construct service identification methods specific to certain situations. Therefore, ideas of SME are transferred into the realm of service identification. The meta model is further applied to a fictitious case.
