A method for selecting a software component, the method being executed by a processing device including a storage unit that stores a software component database that is a database indicating a correspondence relationship between a software component including at least a source code and a software feature indicating characteristics of a software, and heterogeneous features correlation information indicating a correspondence relationship between the software feature and a system feature having a lower abstraction level than the software feature and indicating characteristics of a system, and an input unit that receives a request feature list including one or more of the system features, the method comprising:

• feature conversion processing of referring to the heterogeneous features correlation information and outputting the software feature corresponding to the system feature included in the request feature list, and
• software component selecting processing of referring to the software component database and outputting as a software component selection result the software component corresponding to the software feature output by the feature conversion processing.
